Questions range from what causes hair to turn grey, possible causes of pains, origins of viruses, and anything to do with conditions and diseases associated with health.
Asked in Conditions and Diseases, Animal Parasites
Can parasites transfer from one person to another?
Very definitely YES! There are more parasites that can be transmitted from one person to another than you would probably like to think about! A few choice internal parasites: Amoeba = a microscopic (Protist) that causes Amoebic dysentery. Death from diarrhea is not pleasant. Ascaris = a large, unpleasant intestinal roundworm. Spread by poor sanitation and hygiene. Hookworm = another intestinal roundworm, but not as large as Ascaris. Spread the same way. Tapeworm: potentially several feet long, this flat, segmented worm takes up residence in your intestine and eats what you eat. Easily "broken", each segment is capable of infecting someone else, or re-infecting you if you have poor hygiene. and... what is probably the most deadly organism on the planet... Plasmodium falciparum..... a parasitic protist (microscopic "animal") that causes malaria. It kills tens of thousands of the world's poorest people every year! And then of course there are ectoparasites- they live outside of your body- head lice, scabies, bedbugs, chiggers, etc.
Asked in Conditions and Diseases, Doctors
What kind of doctor diagnoses and treats STDs?
There is not a specific STD doctor; you can see your primary care provider, adult medicine, general practitioner, pediatrician, family doctor, OB-GYN, or urologist. Infectious disease specialists are sometimes consulted for cases with resistant strains, or in the case of penicillin allergy in a patient with syphilis. You can see your primary care provider, gynecologist, urgent care clinician, or local public health department. Any doctor can test for STDs, although some have more experience and training in this area. If you're not sure where to go, consider your local department of health or family planning agency. You can see your regular physician or visit a walk in clinic, you don't have to visit a specialist for VD.
Does cracking your knuckles lead to arthritis?
Arthritis and Cracking Knuckles The reason people associate knuckle-cracking with arthritis because it makes a cracking noise and, if something cracks, it must be being damaged. However, the truth is that nothing is being cracked. A joint is any place where the ends of two bones meet. Where the bones come together they have a covering of "articular cartilage." This is surrounded by the "joint capsule," inside of which there is synovial fluid. Synovial fluid is the lubricant for the joint and also serves as a source of nutrients for the cells that look after the cartilage. Synovial fluid has dissolved oxygen, nitrogen, and carbon dioxide within it. When the right pressure is applied to a joint, the area inside the joint capsule expands. However, the expansion is limited by how much synovial fluid is contained in the joint. Synovial fluid cannot expand unless pressure inside the joint capsule drops and the dissolved gases can escape out of the fluid. The cracking sound comes from the gases rapidly being released from the fluid. There have been a few studies to see whether or not cracking knuckles caused arthritis. None have found that there was an increase of arthritis among knuckle-crackers; nevertheless, a relationship was discovered between knuckle-cracking, hand swelling and lower grip strength, damage to ligaments surrounding the joints and dislocation of tendons. The conclusion of the studies indicated that while knuckle-cracking was not associated with arthritis, it was associated with damage to ligaments that surround the joint and dislocation of tendons. There may also be a connection with soft tissue injuries. For those that would like a more in depth view of tests done on a sample of 300 knuckle-crackers, go to the Related Link below. More input from Wiki s contributors: Cracking your knuckles wears away the cartilage between the joints over a long period of time. This is one of the causes of arthritis. Other causes of arthritis are completely unrelated, like for example, you can inherit it from your parents, or get it because of a disease like Lupus. So, I guess if you might get it anyway, and you might not know if it was your's or your parents fault, go ahead and crack away. Don't listen to those people that tell you cracking your knuckles will cause you to have arthritis. At this point it's just a speculation, not wild, but certainly not founded on anything but misconceptions. All you're doing is playing with the physiology and chemistry of your body a bit. There are good and bad sides to this. Here's a rather complete site if you want to read more (which keeps me from typing it all out): howstuffworks. No, of course it doesn't. A study focused on 300 habitual knuckle crackers found no evidence linking knuckle cracking and arthritis. Chronic crackers did suffer other harm, including soft tissue damage and loss of grip strength. This damage is usually minor, however, and cracking your knuckles actually has some benefits -- you'll feel looser and enjoy more mobility in your joints immediately after popping. No, it only elongates the joints over time and gives you the appearance of longer fingers. No. I'm 20 and I have been cracking my knuckles (toes, back, neck...) since third grade. My knuckles, if I pull the skin tight are a bit larger than normal, but it's not noticeable. My fingers don't look long to me. This is an old wife's tale that has been debunked many times. The crackling sound when you 'crack' your knuckles is just the release of gases (nitrogen if I recall) back into your bloodstream. No one has ever shown that this is in any way harmful but it can be annoying if done habitually. That's probably why the arthritis story originated, an annoyed parent wanted to scare his kids into stopping the practice. I am a paramedic student and EMT, and have also posed this question to my anatomy professor in the past and to nurse and paramedic instructor back in paramedic school. All cracking your knuckles does is release gas build up between the joints and has nothing to do with arthritis. P.S.: The cracking of knuckles is nothing compaired to the every day abuse the joints go through in every day normal use. It takes 20+ minutes for the gases and fluids to get back into your knuckles to get poped again. and it has been proven that the worst thing that can happen is a slightly stretched ligament which is not harmful at all. it is perfectly fine. Don't do your neck though: let the chiropractors do that. Not everybody's joints crack. Some people have a larger separation between the bones and some people can't relax enough to allow the bones to separate. If you can crack and your mom tells you, you're going to get arthritis, she's just yanking your chain. There is no scientific evidence that cracking your knuckles leads to arthritis. However, it can't be good to repeatedly push a joint beyond its normal physical range. Besides that, it's annoying. Cracking your knuckles can cause a decrease in your grip but unless you're signing any multi-million dollar contracts as a pitcher, it's not worth giving up. But it's still annoying. Of course it doesn't. I've been doing it for years and if anything, it increases felxibility and keeps your fingers supple. I would know, I play the guitar and the piano and it always helps. No is your answer, i am a sports and fitness major and i have askeds many of my Prof. and they all say the same thing there is no evidence that cracking your knuckles inflames the joints and leads to arthritis. the cracking causes the bones to pull apart, forming a gas bubble in the joint, and that's what makes the sound. There has never been a meaningful study done that has shown knuckle cracking to be harmful to the finger joints. 25% of Americans crack habitually. Cracking your knuckles will likely not cause arthritis. There is no evidence that it will. However, as a long time knuckle cracker I can tell you that there are dangers to knuckle cracking. You can sprain your joints if you are not careful. I have always cracked my fingers, toes and arm. I also have arthritis and know that it is inherited from my mother (who does not crack). Has anyone thought about maybe it could be the other way around, maybe having arthritis even in the early stages makes some people need to crack their joints. Maybe it is a condition where some people have excess nitrogen buildup in their joints, making them feel uncomfortable and causing pain and related some how to having arthritis. It has been found that there is no relationship between arthritis and knuckle-cracking. There are two main types of arthritis osteo which is non inflammatory form of arthritis, and rheumatoid arthritis which is an autoimmune disease effecting the joints. No there is absolutely no evidence that knuckle-cracking causes any sort of arthritis. Arthritis is a problem that causes a wearing away of normal joint surfaces. Joints are the points where two bones meet each other. These junctions have special linings on the bones to allow motion at the joints. When this special lining (cartilage) is worn away, arthritis is the condition that results. Finger and thumb arthritis is common, because there are 27 bones in each hand! This means that there are many joints in the fingers that can develop arthritis. Furthermore, we are very dependent on our fingers for many normal activities. Any problem that affects these joints can limit many normal activities.

Can metoprolol be used in bronchial asthma patient?
Why does your back itch after you cough a bunch?
I have this sensation too. It is not skin related (unless it is an allergic reaction that makes you both cough and have a rash), but rather a nervous symptom - that is, related to the nerves in your chest. A cough is produced when the diaphragm (the large breathing muscle that your lungs sit on top of) rapidly expands, and at the same time, the throat is closed shut. This quickly builds up a pressure within the lungs. Then, when the throat is suddenly opened, the air is forced out with a coughing sound, and hopefully whatever it is that causes the cough (like irritating phlegm), will be expelled. The constant and repeated moving around of the diaphragm and lungs inside your chest will sooner or later start to irritate the nerve fibres in that area - the become overstimulated. Since many of our "internal" nerves (as opposed to nerves in the skin) are of a kind that we can´t readily feel, the brain becomes a bit confused. It will place the sensations of these nerves not inside your chest, but on the surface of your skin - in this case, as an itch between your shoulder blades. This is called "referred sensation", and is the same phenomenen that makes an inflammated appendix cause an ache around the belly button. As you may or may not have noticed, this coughing-back-itch will not easily be scratched away like a regular itch. This is because it comes from the inside of the body, and not from the outside like if you were being tickled by a feather or had lice.
Asked in Conditions and Diseases, Cold and Flu, Swine Flu (H1N1/09), The Difference Between, Viruses (biological)
What is the difference between a cold and the flu?
They are caused by different viruses and have slightly different symptoms. See related question below for the symptoms of the A-H1N1/09 "Swine Flu". The symptoms of the cold and flu can be hard to differentiate, sometimes not even possible without a specific laboratory test to determine which virus is causing your symptoms. See the related link below for more information on this from US Flu website, Flu.gov. The primary differences are: The flu usually causes a high fever and a cold doesn't cause a fever except in rare circumstance. General aches and pains with the flu are usually present and can be severe, with a cold they are mild. You may feel very fatigued from the flu and this is unusual with a cold. Headaches are much more common with the flu. The usual cold symptoms of stuffy or runny nose, sneezing, and sore throat are only sometimes seen with the flu. A severe cough comes with the flu but is not as severe with a cold. Colds typically begin with a sore throat. Sometimes a mild fever, cough, and/or a stuffy nose are present. It is important to note the difference between a cold and an allergy because of the different treatments associated with each. Cold symptoms can usually be controlled through the use of a decongestant and anti-inflammatory medicine (e.g. Ibuprofen). Fever is not as common in colds as in the flu. Those with colds almost always have fevers under 101 degrees Fahrenheit. There are a few basic kinds of flu viruses but hundreds of cold viruses. Colds are usually milder than the flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems, such as pneumonia, bacterial infections, or hospitalizations, whereas this is possible with an infection with a flu virus. FLU LIKELY (>50% chance of these symptoms) fever 102 deg. F (39 deg. C) or higher (can reach up to 107 deg. F (42 deg. C) in extreme cases) dry hacking cough severe runny nose stuffiness chills (happen during fevers when body adjusts thermostat to raise it's set point) headache POSSIBLE (30-50% chance) sore throat RARE (< 30% chance) diarrhea vomiting COLD LIKELY (>50% chance) runny nose stuffiness coughing frequently POSSIBLE (30-50% chance) fever 99 deg. F to 101 deg. F (37.2 deg C to 38.3 deg C.) chills sore throat RARE (<30% chance) gastrointestinal symptoms like diarrhea and vomiting The 'flu - an abbreviation for "influenza" - is a viral infection of the respiratory passages causing fever, severe aching, and catarrh, and often occurring in epidemics. A cold, on the other hand, a common viral infection in which the mucous membrane of the nose and throat becomes inflamed. Influenza (the flu) is usually a more severe illness than the common cold, which is caused by other respiratory viruses. The 'flu typically showcases symptoms including headaches, chills and cough followed rapidly by a fever, appetite loss, muscle aches and tiredness. Cold symptoms are limited to the upper respiratory tract with runny nose, sneezing, watery eyes, and throat irritation.
How is the common cold spread?
You are most likely to get a cold if someone sneezes or coughs over you or near you. To avoid the spread this way, you need to stay at least a 6 foot diameter distance from the person. Cold viruses are in the air on respiratory droplets for a short time after a cough or sneeze. Although they can travel in the air for only a matter of seconds and for only about a six foot diameter around the person who coughed or sneezed before they drop out of the air onto surrounding surfaces, that is still one of the most common ways to catch a cold. So, being in a crowded public area where you can not stay at least six feet away from others is one of the most likely ways to catch a cold, besides direct contact with the person who has a cold (shaking hands, touching their skin, sharing eating utensils or kissing) or contact with things they have just contaminated. You can also catch a cold from someone else by touching their mucous membranes or picking up respiratory droplets on your hands that have been ejected with a cough or sneeze and then touching your own nose, eyes or mouth, even hours later. Keep your hands washed frequently and avoid touching your face, especially the mucous membranes of the eyes, nose and mouth, and you will more likely stay cold-free. More detail: You can also pick up viruses by touching somewhere a sneeze or cough has touched, e.g., a sick person's hands or used tissues or a nearby counter top or phone. Colds are spread when the viruses enter the body through mucous membranes, typically of the eyes, nose, and mouth. Any transfer of body fluids between an infected person and a healthy person (e.g. a sneeze, a kiss, a shared beverage) can spread a cold. Also, a person with a cold can contaminate a surface such as a table, phone or doorknob with her hands. If a healthy person touches that contaminated doorknob and then rubs her eyes or nose or eats with her hands, she can get the cold. For this reason, regular and thorough hand washing is recommended especially during cold and flu seasons, see the related question below on how to properly wash your hands to remove germs. You can spread a cold by going to school or work or out in public when sick. It is best to stay home and rest to get well, rather than take the virus in public and make others sick, too. For even more detail, see the related questions below.
Where did the Black Death first start and how?
The black death originated central Asia and spread to Europe. It started because of unclean rodents (hamsters etc.) who had infected fleas. The Black Death or Plague bacteria multiply inside the flea, blocking its stomach (nasty!!) and causing it to become very hungry. The flea then bites a host and continuously feeds on its victim (because it is unable to satisfy its hunger). During the feeding process, infected blood carrying the plague bacteria flows from the fleas' stomach into the open wound. The plague bacteria then has a new host,which unfortunately includes Humans, and the flea eventually dies from starvation. ==== It is believed by many that the disease started in China, whose merchant ships brought it west, to Sicily. Near Italy. It was carried by fleas that were living on rats. Once in Italy, it soon spread throughout the rest of Europe. ==== It began in Asia, Merchant ships Brought it to Sicily, near Italy, Carrying the Bubonic Plague to many countries of Europe. Then spread through Europe and Asia killing about 50 million people in all. The Black Death or the Bubonic Plague and its Medieval World history and origins The deadly disease has been with man and part of world and medieval history for a very long time. It has claimed nearly 200 MILLION lives. The first recorded epidemic of the Black Death / Bubonic Plague was in Europe during the 6th Century. The disease truly became pandemic in 1328 - the medieval period of the history of the world. During this period a third of the world population died. We tend to associate the history of this terrible disease with Europe however it originated in the Gobi Desert. The Spread of the disease The disease spread throughout the Western world and reached pandemic proportions due to changes in lifestyle - people were moving from the country villages to highly populated towns. The formation of major cities and increased travel by various world civilisations, the disease rapidly spread throughout Asia. The Black Death (Bubonic Plague) followed the Trade Routes. The Trade routes provided access to all corners of the known world. The increased use of the trade routes ensured that the disease spread throughout the World. We should also remember that it was not just Europe and Africa that were devastated by the deadly disease. Countries such as China suffered horrendously from the 1328 outbreak with their population dropping from 125 million to 90 million during just the middle half of 14th century.
Asked in Conditions and Diseases, Asthma
What different kinds of asthma are there?
1. Exercise-Induced Asthma Exercise can make asthma symptoms worse. This is called exercise-induced asthma. Exercise can cause asthma symptoms in up to 80 percent of people with asthma. Treatment and monitoring can allow people with exercise-induced asthma to participate fully in the physical activity or exercise of their choice. 2. Nocturnal Asthma Worsening of asthma at night is very common. Many factors may contribute to the increased symptoms, including: - Exposure to allergens in the bedroom, particularly dust mites - Delayed allergic response, which may occur three to eight hours after exposure - Chronic sinus problems and/or post-nasal drip - Gastroesophageal reflux - Airway cooling from a drop in body temperature - Decreased effect of medications during early morning hours - Sleep apnea - brief, repetitive cessation of breathing during sleep caused by an upper airway obstruction 3.Occupational Asthma/Workplace Irritants Workplace exposure to certain chemicals or dusts can induce asthma. Some chemicals act as sensitizers, inducing allergic reactions in the airways. Once the airways become sensitized to a specific chemical, even very small amounts can make asthma worse. Other substances, such as dusts, are airway irritants, causing symptoms in employees who have underlying asthma or who are exposed to high concentrations. 4.Steroid Resistant Asthma Airway inflammation and immune activation plays an important role in chronic asthma. Current guidelines of asthma therapy have therefore focused on the use of anti-inflammatory therapy, particularly inhaled glucocorticoids (GCs). While the majority of patients respond to regular inhaled GC therapy, a subset of patients are poorly responsive even when treated with high doses of oral prednisone. This review will examine the mechanisms underlying steroid resistant (SR) asthma. Check out aafa.org. According to this site, there are two types of asthma - allergic and non-allergic. Interesting reading and helpful links as well. The best source of information is a physician (preferably a pulmonologist) & their nurses.
How do you cure gum disease?
Curing Gum Disease: There are many different reasons for gum disease or Periodontal disease and sometimes called "Pyoria". 1) Improper or inadequate home care. 2) Not seeing the dentist or dental hygienist on a regular basis. 3) Genetic disposition. This does not mean that if your parents lost their teeth, you will lose your teeth. This just means you need to be aware that you are a possible candidate for periodontal disease. 4) Occlusive trauma. This means that you bite may be off or you are grinding and clenching your teeth. Usually excessive wear on your teeth is a sign that you are doing this. 5) Habits, such as smoking. This is proven to accelerate the periodontal disease. Most periodontal disease activity if caught early is very easily treated. It may require a deep periodontal cleaning and periodontal surgery. Look in the yellow pages for a PERIODONTIST, who is a gum specialist. Here is more input from others: Brush your teeth, floss them, and rinse with Listerine, also be sure to stimulate them regularly like you are brushing your gums. be gentle! Supplement with a good multivitamin/multimineral, COQ10, and Peri-gum. Ideally amalgam fillings other metal, cavitations, and root canals should be cleaned up. New answer; Brushing and flossing alone cannot completely remove all of the plaque and biofilm from a person with gum disease. If it could, most gingivitis would be non-existent. Plaque biofilm is full of anaerobic bacteria (living without oxygen) that are deposited on your teeth and in the concave root surfaces under your gums. Your brush and floss can't physically reach all of these areas to completely remove these bacteria. However, with an irrigator, you can easily deliver a stream of water to flush the bacteria and loose particles out of these hard-to-reach areas. --------------------- Managing gum disease is all about daily plaque control - essentially sound oral hygiene. That means, in most cases, stopping the plaque in your mouth is really in your own hands. Brush every day. Floss every day. Period. Your dentist or oral hygienist may recommend fluoride toothpaste or tartar reduction rinses. Colgate Total is approved by the FDA for helping to prevent advanced gum disease by reducing plaque and tartar. Dental professionals recommend oral irrigation as a great way to really clean teeth and gums. Oral irrigators get what your toothbrush and floss, don't, so plaque and tartar and the resulting advanced gum disease never come back. Oral irrigators flood the mouth with a jet of water under pressure to flush offending food particles and bacteria from the mouth. And most importantly, from under the gum line where the infection is. It is just like a wound on your arm - you must keep it clean for it to heal. There are many types of irrigators. Fairly new on the market are irrigators that attach to your shower head or your sink faucet such as Waterpik or OralBreeze. A search on Amazon will produce 99% of available products. All types have pros and cons. ================================================================================== New Answer Introduction: Gum disease mainly affects the soft tissue and bone that support the teeth. It is also known as periodontal disease. This type of disease commonly indicates the swollen condition of the gums. Symptoms: Swollen in gums. Puffed gums. Loose teeth. Bleeding gums. To feel pain during chewing. Pus between teeth and gum. Causes: Poor oral hygiene is the common reason for all gum related disease. Always try to brush your teeth at regular interval or else it can cause plaque formation on your teeth. It is a mass of bacteria that easily grows on mouth surface. When you consume starchy food or sweet beverages, bacteria starts to convert carbohydrate into energy and acid at the same time. Formed acid starts to break down your gums and tooth strength. Treatment: Improve your good oral habits such as brushing habits, use toothpaste that contain the right amount of natural mineral, flossing your teeth at regular basis, try to quit smoking, visit your dentist on a regular basis. Mouthwash is the best natural way to kill mouth bacterial, because it contains hydrogen peroxide and chlorhexidine. You can also use a deep cleaning method such as scaling and root planning. Scaling is mainly used to remove tartar and root planning is used to remove rough spots from teeth. Sometimes, this procedure may result in bleeding, light swelling, etc.
Asked in Women's Health, Conditions and Diseases
Can using spit as lube cause vaginal infections?
Vaginal infections can have a wide range of causes, even including stress. Any kind of penetration carries the risk of causing an infection because it can change the natural pH level or the balance of good and bad bacteria. Saliva may cause infections, but it is more likely to occur simply from having sex than from using saliva as a substitute for lubricant. Infections can also occur if the female is not well lubricated and there is friction or dryness during sex. To help avoid infections, try following these steps: 1. Make sure that you are well lubricated during intercourse. This does not necessarily mean that it must all be natural lubrication. 2. Use the bathroom after intercourse. This will reduce the risk of infection significantly, especially for UTI's. 3. Use cotton underwear, and avoid thongs if possible. 4. Wear loose clothing. 5. Change out of your workout clothes as soon as you are done working out. 6. Change out of a wet bathing suit as quickly as possible. 7. Eat yogurt with "live and active cultures." Brands such as Yoplait and Activia have these. 8. Do not use any kind of perfume or perfumed soap around the vaginal area. 9. Do NOT use flavored lubricant or condoms for sexual intercourse. These are perfectly fine for oral sex, but contain sugar and increase the risk of developing a yeast infection or bacterial infection if used during intercourse. 10. Do not sleep with underwear or thongs. This way, your body can "breath."
Is my dizziness the result of ear infections or dental infections?
Answer common. Make sure you see a doctor, just to be sure. If it is an ear infection Your dizziness could be caused by an ear infection, but if it is a dental problem, it is probably inflammation of the TMJ bone in your skull. I have TMJ problems myself, and I sometimes get dizzy, have pain that feels like it is inside my ear, and get headaches and jaw aches from time to time. Either way, you should go to the doctor and have it checked out, but if you have pain in your ears and jaw (and sometimes in your neck), and you feel and popping or clicking in your jaw, you may want to visit a dentist first.

What is arthritis?
Arthritis Arthritis refers mainly to the degeneration or wearing out of a joint, but includes more then 100 different diseases that cause pain, stiffness, swelling, and damage to the joints. some forms of Arthritis can affect other organs of the body as well. The main forms of Arthritis are Osteoarthritis which is caused mainly by wear tear and trauma. Rheumatoid arthritis which is a autoimmune disease. And gout which is caused by too much uric acid accumulating in the blood and pseudo gout can be the result of too much calcium building up in joints the exact root causes for most forms of arthritis is however not known. For more information, contact the Arthritis Foundation or visit their website.
Why does your teeth hurt when you have a common cold?
The very tips of the roots of your top teeth sit very close to and sometimes in your sinus cavity. When you have a cold and your sinuses are blocked and inflammed it put pressure on the teeth which can be very sore. It does not cause any long term damage to the teeth but it can feel just like a tooth ache.
How long does a sunburn last?
Generally depending on your skin complexion and severity of the burn the pain will last 2-4 days, less if the burn is minor, more if the burn is severe(in which case seeing a doctor is not a bad idea). Also peeling which generally occurs with burns, will take a few more days but peeling although unsightly, is not usually painful. Treatment can be applied in many different lotions(aloe vera)/home remedies/etc. Also avoid exposures to the sun to make sure the condition does not worsen which could make the burn last a few more days. If you have blisters on your shoulders, back,arms ect. then sunburn may last about 1-3 weeks, depends on how bad.
Asked in Health, Conditions and Diseases, Pain
What would cause your left arm muscle to ache and feel cold and your hand and fingers to feel very tingly?
It is important that you see a health care professional (doctor or nurse practitioner) to have this assessed, if it persists. The suggestions below from WikiAnswers users are simply suggestions, and there are many other possibilities; if you want a proper diagnosis, you need to be examined. Vascular - There could be some reason for poor circulation to the arm/hand. This is very commonly caused by too much muscle tension in the scalene muscles or the the pec minor muscles. The blood vessels that supply the arm/hand have to pass through these areas, via the subclavian artery, to branch off into the arm. It could also be due to a misalignment of the shoulder. If a shoulder is misaligned in external rotation, it can put a stretch on the blood vessels that pass through that area to supply the arm/hand. Pinched nerve either in your neck, shoulder, or arm. You need to be seen by a doctor before you experience permanent damage. Tendonitis Migraine (hemiplagic migraine) Stroke, Transient Ischemic Attack (mini-stroke) Chronic Fatigue Syndrome/Fibromyalgia Reynauds disease causes constriction of the blood vessels and usually your fingers get numb, turn whitish in color. Angina Repetative Strain Injury, Carpal Tunnel Syndrome- Using a mouse or keyboard, or other tools, in the same position for an extended period of time can be harmful. Cervical Disc Herniations can cause tingling, arm numbness and pain.
How is Swine Flu spread?
How Is A-H1N1/09 (Pandemic "Swine Flu") Spread in Humans? Like most viruses, it enters the body through the mucous membranes - the eyes, the nose or the mouth. Swine flu is spread just like the regular seasonal flu spreads. It goes from person to person through close contact and direct touch, indirect touch, or respiratory droplets carrying the virus from person to person or from person to environmental surfaces through coughs and sneezes. If you touch where a person with swine flu touches, you will most likely pick up the virus and get the swine flu. That is how it spreads indirectly. Stay a minimum of six feet away from someone with a known infection, avoid close contact from crowded places. You get direct spreading when you have skin to skin contact or direct person to person contact with an infected individual, such as shaking hands, kissing, or caring for a child or other infected person with hands-on care. You could be infected by getting too close to someone who has it. Do not hug people who have the swine flu. Wait for them to recover, then hug them. Do not share drinking glasses or eating utensils with someone, this can also spread the disease. There is some evidence to suggest that it can be spread through gastrointestinal means, such as saliva, emesis (vomit), and feces (stool). The importance of hand washing before and after eating, using the restroom, or providing personal care to an infected individual must be stressed. Teach your family proper hand washing technique. (See related question for this information). Flu viruses can also be spread by handling money. See the related question below. What Are Some Ways It Is NOT Spread? Swine flu is not spread by eating pork. Flu viruses are inactivated ("killed") by heating to temperatures of 167-212°F [75-100°C]. Swine flu has not been shown to be spread by drinking tap water that has been provided by a local municipality (regular drinking water). Swine flu is not spread through swimming in chlorinated pools, or by being in the water at recreational water parks that regularly treat the water. It is not spread in fountains that use purified water or spas. There is some risk of catching it at beaches, or at recreational water theme parks from people among the crowds and not in the treated water, just as in any other crowded public place. How Can the Spread Be Controlled? Protect yourself and others by getting your flu vaccination, it is the most important and most effective way to stay well and to avoid spreading the flu to your family, coworkers, and in public. It has been proven to be safe and effective during the 2009 flu season, and since it is made exactly like the flu vaccines in prior years, it has been proven safe and effective over decades of use. Another very important method of prevention is proper and frequent hand washing and regular hygiene. To help prevent swine flu, wash your hands frequently with soap and water, and avoid touching your face, eyes, nose, and mouth. When you have the virus on your hands and touch the tissues in those places, that is how the virus enters your body. See the related question below for additional information about protecting yourself from contracting this and other viruses. The most important protection is basic hand washing and hygiene as described in the related question below. If no warm water and soap is available for hand washing, the hand sanitizers with at least 60% alcohol content can be used (or even plain rubbing alcohol). How Long Can You Spread It When Infected? There are still studies in progress to determine the best answer to this question. The most conservative suggestion from studies by the Department of Homeland Security (DHS), on how long a person remains contagious, seem to back up the initially reported CDC guidelines that one should be suspected to be capable of still spreading the Novel Swine Flu for one full week after the symptoms start or until 24 hours after the fever subsides [while taking no fever reducers] whichever is longer. However, the most recent CDC guidelines indicate that waiting for 24 hours after fever subsides without taking fever reducers is long enough. According to the 9/19/09 DHS report: Swine flu also appears to be contagious longer than ordinary seasonal flu, several experts said. When the coughing stops is probably a better sign of when a swine flu patient is no longer contagious, experts said after seeing new research that suggests the virus can still spread many days after a fever goes away. Using a very sensitive test to detect virus in the nose or throat, [the study] found that 80 percent had it five days after symptoms began, and 40 percent seven days after. Some still harbored virus as long as 16 days later. How soon they started on antiviral medicines such as Tamiflu made a difference in how much virus was found, but not whether virus was present at all. . . Doctors know that people can spread ordinary seasonal flu for a couple of days before and after symptoms start by studying virus that patients shed in mucus. The first such studies of swine flu are just coming out now, and they imply a longer contagious period for the novel bug. Where Has It Spread? Everywhere. It has infected people in every country of the world. This pandemic virus from 2009 (A-H1N1/09) spread faster than any other flu in the past and to every country in the world. It is now (Oct 2010) in the "Post Pandemic Phase" but it continues to be active in small outbreaks in some countries. The World Health Organization (WHO) has developed an interactive map showing the time line and progression of the spread of the Novel H1N1 across the world during the early phases of the pandemic. A link is provided to the map in the related links section below, a flash player is needed to view the map. How Does It Spread In Swine (Pigs)? The following answer is about the strain of H1N1 influenza that pigs get that is not the same as A-H1N1/09 pandemic flu: Swine Flu can be transmitted from a pig to a human, like the human flu passes to humans. For example, if a human touches the pig or something a pig that has swine flu sneezes or coughs on, and then touches his face, mouth, nose or eyes before washing his hands, that farmer could then get the swine flu that pigs get. It is rare, but it does happen every year, mainly to pig farmers. More Information?

Why would someone feel cold all the time?
There are many causes for this. The most common being overly tired. Others include iron deficiency, anaemia, and a slow metabolism and being out in cold weather without sufficient clothing. It could be symptoms of Anemia, Hypothyroidism, blood vessel problem, diabetes and other diseases, once the the feel toward temperature is abnormal, basic checks are necessary to find out if any above mentioned diseases are on the way.

What could cause twitching in your fingers and thumb along with a strange feeling in your forearm?
I just recently experienced twitching in my thumb while trying to write. I had carpel tunnel surgery about 14 years ago and have had no problems so far till now. Just recently I also started experience pain in the middle of my hand traveling up my arm. This could all be related to the previous carpel tunnel problem. I don't know. Old axiom: "If you hear hoofbeats, suspect horses" applies here. In other words there are a myriad of injuries or diseases that cause what you describe, so odds are it's likely this is a repetitive motion injury. If you have insurance that does not require a referral, go straight to a neurologist, because you are describing something that involves a nerve trauma or change. If you need a referral, (unfortunately, most specialists do even if your insurance does not) call your primary care doctor and ask for one rather than visit the PC doc because you will be wasting your money. Insist on it. He or she cannot help you; you need very specific tests having to do with how and why those nerves are malfunctioning. A family practice doc simply isn't equipped and you've already wasted your money. You need a neurologist to start with some simple tests to rule out the most common causes (carpal tunnel as you and many here have stated) down to a complicated condition known as Complex Regional Pain Syndrome (or regional pain dystrophy was the old name). Paula Abdul has this condition and it makes me sick when people ridicule her. The condition is so severe she requires non-narcotic medication, but it starts with tingling and numbness due to nerve injury (in her case, dancing). There is also a genetic condition that can cause your symptoms and it starts in the shoulder and/or rib area. Parkinson's Disease starts this way, too, as does some forms of epilepsy. Family history and the type of work/play you do (diabetes? stroke? heart attack? autoimmune diseases? long hours on the x-box?) is most important for the physician to know. You are describing a type of neuropathy and your answers to the doctor may lead to a clinical diagnosis. Educate yourself about the difference between a clinical diagnosis or one made by an exact fact or set of exact, indisputable facts. Have you ever used street drugs? Doc needs to know. It's imperative to be completely honest with the doctor. If he or she passes judgment, fire the idiot. That's not a part of the oath. Tests are numerous so if a clinical diagnosis is not made right away, be prepared. Some tests can be done in the office like nerve conduction tests, fasting blood sugar, specialized urine tests, basic blood work that will look for vitamin, mineral, numerous factors that are out of the norm as other writers have noted correctly. Other tests must be performed at an outpatient facility, like a spinal tap, MRI (to rule out a brain tumor, spinal cord, or disc disease or injury), sophisticated blood work that require supervision (like NPO, brain wave studies, etc). Most important, don't ignore your symptoms. There's a 99% chance they are caused by repetitive motion and will heal on their own by a change in the way you use your arm. You need to know, though, and the sooner the better. If you find yourself down the road with no answers, get to a Pain Management doctor (usually an anesthesiologist). Not so much for the pain, but these physicians simply will not treat a patient for pain without knowing what is causing it. Therefore, they tend to be the best and most gifted diagnosticians out there. An added bonus is that they truly don't care to see patients suffer and are devoted to finding solutions/answers. There are a number of conditions that could possibly cause the feelings you are describing. Carpal Tunnel Syndrome (CTS) is certainly one of them, however, depending on symptoms, CTS can be easily ruled out by a qualified Physician. The problem in your hand and arm could be more proximally located and could be a result of a cervical radiculopathy or other cervical pathology e.g. spondylolisthesis, or cervical stenosis. The twitching may also be a result of a systemic imbalance in electrolytes that can cause cramping and/or pain. Also, consider that muscle twitching is a normal part of human physiology as the muscles may spontaneously depolarize for any number of reasons. Overall lesson, go to a doctor and recognize that most of what's on this website is anecdotal and should not be trusted. Yes, to some extent it is true that carpal tunnel can be a major cause of twitching in the forearm. But it can be caused by the nutritional deficiencies too like hypocalcaemia (and hypomagnesemia) i.e. calcium deficiency is the most usual cause which leads to twitching. It can be caused by many things. Certainly many of the above things that been listed, but also Multiple Sclerosis, or ALS (or Motor Neuron Disease) in rare circumstances. ALS has an incidence of approximately 1 in 100,000 and generally strikes around the age of 50. Please get this checked out by a neurologist. The most pertinent advice offered so far is for you to have an evaluation by your primary care doctor. Pending your doctor's evaluation you may require a consultation with a specialist known as a neurologist. While there are a variety of conditions that can cause your symptoms, 'intention' or 'positional' tremor should be added to the list already offered (i.e. electrolyte imbalance, neck or cervical problems, and various neurological disorders including Multiple Sclerosis(MS) or Amytrophic Lateral Sclerosis (ALS) This is why you should begin your evaluation with your primary care doctor who, through physical exam, laboratory testing and possible radiographic imaging, can either provide you a diagnosis or an appropriately directed referral to a specialist who can provide further insight into the cause of your condition.
Is acne normal during pregnancy?
Pregnancy can trigger acne or make existing adult acne worse. (On the other hand, some women with acne-prone skin report a decrease in breakouts during pregnancy, so you never know.) Higher levels of hormones called androgens are at least partly responsible for pregnancy breakouts because they can prompt the sebaceous glands in your skin to get bigger and boost production of an oily substance called sebum. This extra sebum, combined with the shed skin cells that line your hair follicles, blocks your pores, creating an environment in which bacteria can rapidly multiply. All this can eventually lead to the inflammation and skin eruptions of acne.

What could cause sharp shooting pains in various parts of the body?
It's life's reminder that you are mortal. Get plenty of exercise, stop eating junk food, love the people around you, and if the pain happens to continue, then see a doctor. SHARP SHOOTING PAINS IN VARIOUS PARTS OF THE BODY CONTROL CENTER OF OUR BODY: Our knowledge of human body is somewhat distorted. We don't accept the facts that, 1. The skeletal muscular system is the control center of our body 2. It is the one and only system in our body that we can feel and control. THE UNIFIED SKELETAL MUSCLE: Normally, all the skeletal muscles of our body should isometrically act as though it is just a single skeletal muscle. This Unified Skeletal Muscle must normally have a tone (isometric contraction) of 50%. PAIN AND ACHE: We don't know the differences between pain and ache. Normally, a skeletal muscle should have 50% tone. 1. Pain is due to extreme isometric relaxation of a skeletal muscle 2. Ache is due to severe isometric contraction of a skeletal muscle. Thus, pain and ache can co-exist or alternate. CAUSES OF SHOOTING PAINS AND ACHES: Under abnormal conditions the skeletal muscular system may isometrically contract or relax towards a single or multiple points leading to severe aches and pains. This occurs in many medical conditions. Diabetes, anxiety, head injuries, genetic disorders, etc. are common causes. SIMPLE AND THE MOST RELIABLE REMEDY FOR SHOOTING PAINS: Even if the medical cause of the shooting pain is known, the treatment, even if there is one, rarely gives satisfactory relief. Original Meditation, a set of isometric exercises, should be effective in most cases. In this all the skeletal muscles can be made to contract and relax as a single unit and its contraction or relaxation towards any point can be abolished.
