It is important to remember that everybody's experience is different. It is also not uncommon to have a different experience with each consecutive pregnancy.
The time of the year can effect your symptoms. Summer pregnancy's tend to be harder and more exhausting.
Some common symptoms of pregnancy include:
- Nausea or full blown morning sickness
- Food cravings
- Dramatic increase in breast size
- Sore, tender, swollen breasts
- Itchy skin (breasts and belly)
- Widening of the hips
- Expansion of the rib cage
- Weight gain
- Skin conditions ie. rashes, acne
- Feeling hot
- Swollen ankles
- Water retention
- Back pain
- Glowing skin
- Thick healthy hair (increase in hair volume)
Attention Deficit Disorder, or ADD, is hard to define due to the fact it encompasses so many differing symptoms. The common traits are usually difficulty to pay attention due to being distracted easily, forgetfulness, inability to process future implications of actions and low or underweight, lean bodies. In some cases, though, instead of distractions being harder to avoid, people will hyperfocus, or not be aware of anything at all but what they are doing, and oftentimes obsess when making conversation. Many cases are in between. The problem falls in the fact that it encompasses such a wide range, there are intermediate cases and unique cases. A link between add and children's depression is theorized due to medications that treat add sometimes causing depression. It also goes the other way around.
Hope this helps, and for more information try finding a good psychologist or psychiatrist and ask if you think you may have it.
ADD is when you cant focus and you don't pay attention all the time when you are suppose to. your mind wanders all the time and you can hardly sit still. you space out a lot more then normal and you have a hard time keeping friends.
Impatiences also is very common.
Here are people answering and sharing their experiences about ADD:
My dad used to ask me if I was doing drugs, which I wasn't.
I will turn on the news to watch the weather only to find myself watching the sports since I had "taken a mind trip" for about 15 minutes. This happens quite frequently. I can even think about the fact that I may do this when I turn on the news so I try to pay attention and It still happens. It's crazy!
I make lists for everything too but can't find them most of the time.
For years I purchased over the counter ephedrine at the gas stations. This made me feel as normal as possible.
I didn't know that I had ADD but I knew that I was different from most others and often have a hard time keeping friends, boyfriends, jobs or anything else for that matter...loosing lots of stuff.
When I get on the Internet all holiness breaks loose cause I can have 20 screens open at a time, going from one topic to another, jotting down notes incessantly.
I really thought I was crazy until I was diagnosed. I was 39 when diagnosed. My daughter has been diagnosed as well. She is 16 and I'm so glad that she won't have to go thru her life thinking she is "less than" because of this condition.
It would be unusual for an adult to suddenly get Attention Deficit Disorder as it is usually something that happens in childhood and carries through to adulthood. Adults with ADD / ADHD struggle daily with self-regulation, regulating their attention, regulating their impulses in talking and action, and regulating their emotions.
But this condition needs to be diagnosed by a doctor as there are other disorders that have similar symptoms
you get hyper
You are extremely hyper all the time, get distracted really easily, and like to talk ALOT. Those are the basic symptoms of ADHD.
Ones memory only retains the strange and unusual, unless the person is tutored. When tutored they can become honor roll students! Terrible at spelling words forever.
Keeping one attention on things is difficult. Doing exercise like riding a bike fast, breathing deep just right can take this away for about 12 hours. The terrible spelling stays.
No drugs can help; just the opposite!
Believing in God dose help.
Reasons for Menstrual Period Symptoms
Studies indicate that almost 80% women suffer the effects of menstrual discomforts. The world over women experience some typical symptoms of menstrual period flow. But we first need to know the mechanics behind the activity to understand why these symptoms appear and what makes them such a problem.
Every month a woman's ovaries release one egg into her uterus. This egg stays there , waiting to be fertilized, and after a few days, is discharged from the uterus along with its tissue lining . This was the lining that had been prepared by nature to create a soft, warm cocoon for the fetus that would have been conceived had the egg got fertilised. This is nature's own baby basket and its warm lining.
But when the egg doesn't get fertilized, and is expelled from the body with a bloody vaginal discharge, this is called the menstrual flow. This process is called menstruation. As this blood, tissue and the egg flow out from the vagina, they cause some physical discomfort but most of the pain associated with the menstrual flow is largely hormones related.
Menstrual Period Symptoms
The most common symptom of menstruation is the pain in the abdomen. In many cases this is located at the lower abdomen or lower back area. The pain usually starts from a couple of days before the actual flow starts and is generally referred to as PMS - Pre-Menstrual Syndrome. There are other symptoms that are equally discomforting but until very recently it was dismissed as female drivel , fuss over a pain that is nowhere else except for in the imagination. But science has now established that discomforts and pain during the menstrual flow are not psychological, they have very physical roots. Most of these pains are caused by dramatically fluctuating hormone levels in the body. Whoever said that the ability to give birth would come easy?
The pain or menstrual cramps usually come because during the first five days of the menstrual period, the uterus is contracting in spasms, in order to shed the lining. The pain is a much milder form of what she will experience during childbirth, also a contractions- led activity. The muscle contractions here are cause by a chemical called prostaglandins. This hormone causes the muscles of the uterus to contract for a longer period of time, sometimes depriving it of oxygen. This is what causes menstrual cramps.
Then after 14 days, the hormonal level changes to prepare for the release of the next egg. The hormone levels of both estrogen and progesterone keep rising till about 4 days before the next period, and then, if fertilization has not taken place, they fall. This sudden change causes more irritation and emotional imbalance in a woman. People refer this discomfort to, when they talk about 'that time of the month'.
Around the time ovulation happens there is a pain in the back, abdomen or even dizziness. Just about a week before the actual menstrual period flow starts, the woman may experience bloating. This is water retention on legs and around the middle, sometimes even the face. The other symptoms are breast tenderness, decreased activity levels and lack of sleep. Some women also experience changes in appetite while some others break out in acne. There sometimes seems to be a slight loss of coordination, so many women experience trouble in driving in this PMS state. A woman approaching this time usually experiences attacks of anxiety and social withdrawal. The most common of all symptoms, is irritability or moodiness, depression and angry outbursts. Nausea, headache, gas in the abdomen, indigestion and sometimes even diarrhea are common symptoms and pains of menstrual period. If these pains get more severe than normal, they are taken to be a disorder called dysmenorrhea.
The bad news is that menstrual pain and discomfort does not spare any woman who is in the fertile age bracket, usually between 12 and 51. Class, culture, body type, even race make no difference.
Symptoms of H1N1/09 (Pandemic swine flu):
Having a single one of these symptoms does not mean you have pandemic swine flu, but, you don't need to have all of these symptoms to suspect infection, either. The symptoms of swine flu in people are similar to the symptoms of regular human seasonal influenza. Watch for some combination of the following symptoms:
Caution: If you suspect that you might have a flu infection, consult a physician as soon as possible. Don't wait!
It is important for people who have chronic health conditions, women who are pregnant, and people with other high risk factors to pay special attention to warning signs. Influenza can make the symptoms, of other chronic medical conditions, worse
For Children: who may need urgent medical attention, symptoms include:
These are warning signs that physicians think about all the time with respiratory infections and are good things for parents to have in mind at all times but especially with the Novel H1N1 strain.
For Adults: who may need urgent medical attention, symptoms include:
Other underlying medical conditions* can create the potential for more severe illness, and it is for that reason that people who have these underlying conditions, or the family members who care for such people, need to remain vigilant about these warning signs emerging. For a list of the those at most risk of the swine flu and of complications due to it, see below.
It's often best to contact a health care provider for advice before going to an office or care center and waiting for an appointment. That's also a better strategy than going to an emergency room, but these warning signs can help people differentiate a cough or cold or respiratory symptoms without warning signs, from the type of signs that might lead you to want to get help from a medical provider urgently.
To prevent catching swine flu, colds or other strains of flu and viruses:
If you live with or care for someone known to have the swine flu virus, you should assume that you, too, can spread the disease. Wear a surgical face mask (model N95) while contacting and tending to someone with a virus, especially children, in case they cough or sneeze when you are close to them. Wash hands always before you touch your face, nose, eyes and mouth and before (as well as after) you touch other people's faces, mucous tissue. You should also wash your hands after you cough or sneeze and always use a tissue to cover your mouth and nose. Immediately throw the tissue away after one use. Wash your hands after touching used tissues. Cough into your elbow if you do not have a tissue. Don't use your bare hand unless you wash hands immediately after and before you touch anything or anyone.
To prevent spreading swine flu, colds or other strains of flu and viruses:
Even if you do not yet have symptoms, you can have the virus and spread it before you know you have it for one or two days after catching the flu. When you know you have been exposed, or when you know the risk is high for catching it, wash hands very frequently.
Stay home from work or errands when sick, and keep your kids home if they or others in your family have any symptoms. The schools will recommend if it is safe for your children to attend school if there are other children from the school infected. Be prepared with day care alternatives if the schools announce a closure. Flu virus can live for approximately two hours on hard surfaces, perhaps longer on moist or soft materials. Use disinfectants recommended for control of viruses on surfaces that are commonly touched, such as telephones, door knobs, light switches, TV remote controllers, chair arms, public pens and pencils (take your own), and grocery cart handles, as well as the lavatory knobs, handles, and surfaces.
For additional information on preventing exposure to and distribution of the flu viruses, see the related questions below.
*Underlying Medical Conditions or Other Factors That Create Higher Risk:
Information for those in the UK, from NHS:
A doctor faced with a symptomatic patient cannot yet predict with certainty the course of their illness and whether or not they will be in the small proportion who may become more seriously ill. This is why antiviral medication is still being given to all those with swine flu in the UK, subject to their doctor's discretion. A doctor faced with a symptomatic patient cannot yet predict with certainty the course of their illness and whether or not they will be in the small proportion who may become more seriously ill. This is why antiviral medication is still being given to all those with swine flu in the UK, subject to their doctor's discretion.
More information taken from the NHS website:
It is important that as swine flu spreads, you know the symptoms of the disease so you can recognise it in yourself and others at an early stage.
Please read the information about the swine flu on the NHS website and consider your symptoms carefully before using the National Pandemic Flu Service mentioned below.
During the pandemic in 2009, most swine flu cases were mild, with symptoms similar to those of seasonal flu. Only a small number of people had more serious symptoms.
If you or members of your family end up with a fever (high temperature over 38Â°C/100.4Â°F) along with two or more of the following symptoms, you may have swine flu:
Checking For Symptoms:
It makes sense to always have a working thermometer at home, as fever is one of the main signs of this and many other infectious diseases.
The NHS website provides a National Pandemic Flu Service#. If you are concerned you may have swine flu, stay at home and check your symptoms using the online guides at the pandemic flu service.
Call your GP directly if:
# Note: the National Pandemic Flu Service is a new online service that will assess your symptoms and, if needed, provide an authorisation number that can be used to collect antiviral medication from a local collection point. For those who do not have internet access, the same service can be accessed by telephone on:
For more information available on the National Pandemic Flu Service site go to Flu Service: Q&A.
For most people, swine flu is a mild illness. Some people get better by staying in bed, drinking plenty of water and taking over-the-counter flu medication.
However, some groups of people are more at risk of serious illness if they catch swine flu, and will need to start taking antiviral medication as soon as it is confirmed that they have the flu.
It is already known that you are particularly at risk if you have:
Also at risk are:
It is vital that people in these higher-risk groups who catch swine flu get antivirals and start taking them as soon as possible, preferrably within 48 hrs of first signs.
This information is from health care professionals and groups such as Mayo Clinic, and should be used as a point of reference or as a generality, because each pregnancy is unique:
Morning sickness is a symptom some women feel during early pregnancy. It starts after conception which may or may not occur after unprotected intercourse. So, first confirm that you are pregnant by using a home pregnancy test, and if positive, make an appointment for a health care professional to confirm those results and to start prenatal care.
Once you have a confirmed pregnancy, the morning sickness usually starts around the first 4 to 6 weeks of pregnancy and it tends to get worse over the next month or so after it begins. However, for some women, the queasiness begins as early as two weeks after conception.
Morning sickness for the majority of women stops around the 12 th week, but for many women it continues until the 14th to 16th week. About half of the women feel complete relief by 14 weeks. For the rest, it may take one more month or so for it to stop. It can return later, and for some unlucky women it can come and go throughout the entire pregnancy. There isn't a set time for it to stop because each woman is different, and each pregnancy is different.
If nausea and vomiting persists well into the second trimester (after the 13th week) you should contact your doctor just to be on the safe side. It isn't harmful to you or your baby unless you have excessive vomiting and can't keep anything down. If you are unable to eat or drink fluids and keep it down for 24 hours straight, you may have something called hyperemesis gravidarum. This condition can be harmful to both you and your baby, so you should contact your doctor right away to see if you need any special treatment.
As stated above, each pregnancy is unique, so here is some information from various contributors about their experiences:
that your having a nose bleed.
if you get one:
hold a Kleenex up to your nose, while pinching the uppermost portion of you nose , and holding you head down.
If you are not bleeding a lot, it can be from cold air, dry heat in the house. I live in British Columbia where we can have rain and damp, then have freezing weather and the next day it's warm. Even the furnace being on in the house is drying. Look at your skin and if it looks dry, you bet your nose is dry. Even air conditioning can do it to you. You can use a little KY Jelly or vasoline inside your noise to keep it moist. As long as you are not bleeding profusely then there is nothing to worry about. If you've been blowing your nose often you've probably just given yourself a nosebleed by rupturing the blood vessels at the back of your nose. It's no big deal. It heals on its own. There are nose drops specially suited for this condition. Also saline nose spray can help. Try drinking more water and blowing your nose less. Everytime you blow your nose, you can be breaking up your clots. Give your nose time to heal, about a week. == ==
In most cases, it is not possible to start having symptoms so early, since it takes the female body about two weeks to produce the HCG (pregnancy) hormone that make you feel pregnancy symptoms. However, every woman is different. Following are several opinions and experiences on this issue from s.com contributors.
Please visit the discussion page if you would like to add to the discussion on this topic.
Experiences from s.com contributors
The simplest identifier is they do not turn their head when their name is called. Other normal babies look up from what they are doing when their name is called; autistics don't. When my child was born he would not even open his eyes to look at us. He sucked on his hand and hummed from the moment he was born. As the weeks and months passed he displayed behavior that was different from other children. He never anticipated that food was coming. Typical babies stop crying when you pick them up to feed or change them because they learn that care is coming. My first two anticipated that care was coming. My autistic child did not. When he was a toddler he did not grip when I held him as my first two did. He was dead weight. From the time he very small,as young as four months, he did not like switching from long sleeves to short. He avoided eye contact from the time he was born. Typical children seek eye contact. We felt that he did not need us in any emotional way like our first two did. He was very content with himself except to be fed and changed. He hummed himself to sleep from the time he was a few months old. He never seemed to take information in by observing. Everything we taught him had to be hand over hand. AUTISM is also called "Autism Spectrum" because someone with autism can be highly intelligent and author books on autism, or they can be severely disabled and need total care. And everywhere in between. Some early symptoms can be early speech, then not a word thereafter. Other symptoms include lack of eye contact, lack of affection (hugging them is actually "painful",) "flipping or flapping" their hands or objects, crying and being self abusive, obsessed with certain objects or activities, repetitive behaviors, not meeting "normal" milestones, odd eating rituals (will eat only 3-4 food items) and many other behaviors. There is no magic cure. Do some research, love your child and work to have them achieve what "professionals" say they will never do. On a recent course I learnt that a severally autistic child lives completely in their own world. they are usually unaware of their surroundings and people are just objects. They learn to 'use' people to get what ever it is they need but they do not usually form any type of bond. There is little eye contact and they be obsessive with objects. some autistic children can speak, other will not, but as a parent you may be able to teach your own method of communication, so that it is easier for the child to 'communicate' their needs and for you to understand them. An autistic child needs to have a very structured routine. They only feel safe when they know what is coming next. When learning a new routine it may be useful to carry out the same procedure many many times in different rooms as autistic children do not generalise (they dont take what they have learnt to any other place other than the place it was learnt in). establish routines and stick to them. do not introduce new things until complete familiarity has been establised Be patient, improvements will happen, really hope that this helps. I feel that the above answer is very misleading. There are degrees of Autism from mild or high functioning to severe. And yes there is no "magical Cure" but a child can recover. Children with Autism do not make eye contact, but some of them do show emotion and some do develop language. My personal belief is the some children with Austim have been injured by a variety of factors in there environment. For example, with my child it was partly genetics, he was born with a compromised immune system, then he had RSV Virus as an infant, he was given too many antibiotics as a baby for various ear infection to the point where he bled out of his colon and the vacines were the final attack on his system. Basically, like a computer, he crashed and his systems (primarily his brain function and nervous system) just couldn't take any more. My baby was saying some words at 6 months , he was making eye contact and pointing at objects. At 18 months however, the language disappeared as did the eye contact, he was ritualistic and repetative For instance, he loved anything that spun and could sit and spin objects for hours. Ceiling fans facinated him. His twin brother was right on target and so I became frantic when in my heart I new what was going on. I was devasted when I got the diagnosis but determined not to let him stay this way. First he began intense therapy of about 30 hours a week of ABA (Applied Behavioral Analysis - this is a miracle worker), Speech and Occupational Therapy. I started to research and read everything I could and found out about special diets such as the gluten free / caesin free diet. This did not work for my son (it doesn't work for every child and its a miracle with some children). I learned about vitamins, probiotics and supplements. I started him on supplements as soon as I could and this was the turning point for my son. Amongst the supplements that I gave him, I purchased this really expensive juice called Mon Avie which has antioxidants and phytonutrients (the original formula) and saw subtle improvement. Then I started him on DMG and Acidophilus and saw some pretty significant change. I am going to try a vitamin supplement now called Super Nuthera from Kirkman Labs (they will happily guide you and answer questions). I also want to start methyl B12 vitamin strips. One thing at a time. Today he is a happy vibrant 3 year old who attends a typical nursery school with some support which we hope will not be needed soon. He talks and has an amazing personality.
* I had chest pain as first sign of pregnancy. Went to doctor and refused to do x-ray since i was trying to get pregnant. Pregnancy test was negative a day before. It was stabbing pain for few hours and then gone. When went to doctor, and that day at doc office it turned out positive (it was the day 28). they said it is because of change in hormones.
* All women experience them at different times. Some women say they never have symptoms. But I'd say the average is at about 4 to 6 weeks. If you think you're pregnant wait until you are a day or two late and take a home pregnancy test, this will help figure out if you are pregnant. == == == == * Many women begin noticing slight symptoms within a day or two of implantation, which usually occurs 7-10 days after conception (not necessarily the same as 7-10 days after sex!). The pregnancy hormone, HCG, is not present in the bloodstream until after implantation, and sometimes can be detected by an early home pregnancy test as soon as 10 days past ovulation if pregnancy has occurred. After implantation, some women begin to feel the typical signs of early pregnancy -- sore breasts, slight nausea, etc. A friend of mine swears she always knew she was pregnant before she missed her period because her sinuses started acting up for no reason with all three of her pregnancies several days before her period was due. It's really very different for every woman. Having no early symptoms is normal, but having several is normal, too.
Symptoms of the Flu Although each person and each type of influenza can have varying symptoms, the most common general symptoms are:
For adults the following symptoms are indicative of more serious complications and you should seek urgent medical attention if you have:
Babies and small children with flu can also have the following symptoms which should also be followed by a pediatrician or family doctor:
Additional related information:
Some of the secondary conditions related to the flu can include bacterial or viral pneumonia, ear infections, and sinus infections.
Complications from the flu can include dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes and/or worsening impacts from immuno-suppressed or immuno-stressed states such as pregnancy, HIV/AIDS, cancer chemotherapy drugs and radiation therapy, and immuno-suppressing medications after organ transplants.
Seasonal influenza, often called "the flu", is a contagious respiratory illness caused by influenza viruses and occurs every year. Flu season in the northern hemisphere can begin as early as October and last as late as May. It also occurs in the cold part of the year in the southern hemisphere, which is during the summer time in the northern hemisphere.
The single best way to prevent the flu is to get a seasonal flu vaccination each year. September or October is the best time to get vaccinated in the Northern Hemisphere, but if you have not caught the flu by then, you can still get vaccinated effectively as late as March.
INfluenza usually appears in epidemic forman effects may people at once
Epilepsy is diagnosed by a person having seizures. For some people the seizures are frequent and strong. Someone having a milder form will not get seizures very often. The seizures they get will be very mild, maybe manifesting themselves as short periods of loss of conciousness, or even just feeling a little "strange" (hard to really describe this as it is different for different people) for a moment and then feeling fine. They may feel like a seizure is coming on, but it never actually happens. Most seizures are preceded by something as a person feels it coming on. This is normally called an aura, which is different for different people, the strange feeling I mentioned. It could be a physical sensation. The seizure will then follow. Someone with a mild form may get an aura, but not have a full seizure at all.
some of the other side symptoms are that the person see double of evrything and sometime walks like they are drunk
Yes, you should contact your doctor. It can depend on what you are sick with, but whatever it is, you should consult your primary health care professional. It can be very bad for some people and not good for others. It likely does represent a loss of a lot of water weight because fat does not burn away that quickly. You are probably either dehydrated or at risk of serious dehydration from that. Loss of fluids in that amount from your body could come from profuse sweating with fever, vomiting, diarrhea or overuse of diuretics.
You obviously know...since you posted this in the ALLERGIES section!?! You need to go to the Emergency Room because you are in Anaphylactic shock.
98.6 degrees Fahrenheit
The normal body temperature in degrees Celsius is between 36.5 and 37.0
The condition is NOT true "lock jaw". Rather, a sore jaw on one side that makes it hard to open your mouth or chew is most likely that you clench your teeth at night. It's a common problem to many people living in these stressful days. A dentist can evaluate your bite and make a mouth guard for you to wear at night. The mouth guard helps to prevent clenching and so it keeps the jaw/facial muscles from going into spasm during the night.
Until you see the dentist, apply ice--not heat----to the jaw in front of the ear. Ice can be left on about 10-15 minutes, then off. You can repeat several times a day.
A muscle strain or an entrapped brachioradialis nerve. A swollen lymph node. Many thing, actually.

In medicine, Cerebral softening (encephalomalacia) is a localized softening of the brain substance, due to hemorrhage or inflammation. Three varieties, distinguished by their color and representing different stages of the morbid process, are known respectively as red, yellow, and white softening.
This is one of the sequelae of "Pulpy Kidney Disease" or "Overeating Disease" in lambs and kids. A sudden access to diets rich in starch promotes the rapid proliferation of Clostridium perfringens Types B and D, in the large intestine. This bacterium produces epsilon toxin which causes endothelial damage throughout the body, especially in the kidney and brain.

Encephalomalacia is the softening or loss of brain tissue
An adhesion is a band of scar tissue that binds 2 parts of your tissue together. Adhesions form as a natural part of the body's healing process after surgery. As part of the process, the body deposits fibrin onto injured tissues. The fibrin acts like a glue to seal the injury and encourage deposition of cellular matrix but may also cause tissues that should be separate to adhere to one another, held together by an adhesion. Over time, as part of the healing process, the body will either break down the adhesion and replace it with normal tissue or form a permanent adhesion.
While some adhesions do not cause problems, others can prevent tissues and organs from moving freely, sometimes causing organs to become twisted or pulled from their normal positions.
Adhesions may appear as thin sheets of tissue similar to plastic wrap or as thick fibrous bands.
The tissue develops when the body's repair mechanisms respond to any tissue disturbance, such as surgery, infection, trauma or radiation. lthough adhesions can occur anywhere, the most common locations are within the stomach, the pelvis and the heart. It often occurs after surgery.

However, every woman's body is different and reacts differently to pregnancy, even to different pregnancies. The best thing for a woman to do, if she is concerned, is to call the doctor (nurse mid-wife, etc.) or the doctor's nurse. Tell him or her exactly how you are feeling. They can reassure you or ask you to come in for an evaluation if they have a concern. If you have called and still don't feel right, just make an appointment. You don't need permission. If something isn't feeling right to you, or you're worried, go in. Any caring, good doctor (or other professional) will take the time to listen to you and will even offer to do an ultrasound for further assurance (mine does one the very first visit, and schedules a follow-up if he has any questions about the pregnancy). Ask for an ultrasound if one is not offered. (This may not be as attractive an option if your insurance won't pay for one at this early stage, or if you have no insurance, so consider how much you want to pay for peace-of-mind.)
This is the medical term for rapid breathing. So the signs would be....rapid breathing. For example - after excercise. It may also be related to ill health if no excercise has been taken. People with an overactive thyroid (thyrotoxicosis) may exhibit tachypnea as their metabolic rate is increased.
It is usually because you have a fever, and the way the body deals with a fever is by sweating to cool itself by evaporation, just like it does when you are out in the heat of summer and start sweating to cool off. Being hot also will dilate your blood vessels of the skin to move more heat out of the body faster. But you usually don't feel the chill (or as much) when you cool off if the heat is coming from the outside on a hot day, like you do when the heat is coming from the inside with a fever.
A fever is an increase in the core body temperature and the extra heat from that (which the body uses as one of its ways to kill germs) radiates out of your body through the dilated vessels and cooling skin.
Your hypothalamus gland (also called the "brain's brain") functions as the body's thermostat, among many other duties. And, because it is making its temperature control decisions based on the core body temperature, it will not stop the cooling measures until the core temperature comes down, even if your skin and outer layers are no longer hot. The skin then may feel the sensation of cooling from evaporation, which you can also feel to the touch. That can trigger shivering which the skin does in reaction to feeling cold.
But since the hypothalamus uses the core temperatures, it continues to try to cool until the fever is gone. So in a sense two body systems are working against each other...but the hypothalamus wins. It takes longer to cool the inside of your body than it does to cool the outside. So, even though you can feel the cooling off on your skin, and even get the sensation of chills from drafts and being cold on the wet outside of your body, it is still trying to cool the core temperature deep inside. That can make you feel cold on the outside even though you are still too hot on the inside.
Many people believe that if they feel a chill with a fever they should bundle up tight and get in bed and "sweat it out". This is a fallacy. This is especially important for infants. Do not wrap them up in blankets that way, since that can increase the fever. It also increases the perspiration and adds to dehydration from a fever if the liquids are not replaced. Any time infants have a fever, you should contact the pediatrician for advice and do not give them fever reducers without the professional advice to determine if it is appropriate.
