Yes, most people are latent carriers, meaning that they don't show any visible symptoms of actually having the virus.
No.
A kind of herpes (Herpes zoster) which spreads half way around the body like a girdle, and is usually attended with violent neuralgic pain.
Shingles is the clinical manifestation of activated herpes zoster viruses that normally live within nerves reaching the skin surface, forming painful papular lesions in a dermatomal distribution specific to their home nerve.
Post herpetic neuralgia is "nerve pain" that can persist after an episode of Shingle (herpes varicella-zoster). It can be mild to severe and is usually described as burning or tingling. About 10-20% of people will have continuing pain at 3 months after the shingles episode with about 3% having pain for a year or more.
There is no cure for herpes zoster (shingles), but anitviral medicines, such as Acyclovir, can shorten the duration of the break out and help reduce pain. To help treat the pain associated with shingles, your doctor can also prescribe antidepressants, steroids, or a topical steroid cream, and creams to help the itching. Taking an over-the-counter pain reliever may also help. Ask the pharmacist for suggestions for over-the-counter treatments.
Herpes zoster has an acute phase when the skin lesions are present. In a week or two, the skin lesions resolve, and then many people have a chronic pain syndrome for months or years afterwards.
Yes. Trigeminal nerve involvement can include lesions in the mouth and eye. Eye lesions can cause serious problems if not treated with emergency medical care. Mouth lesions while bothersome and sore can be relieved with medicated mouth washes. Here is a good link for loads of extra information about Herpes Zoster (shingles)
Herpes zooster can cause shingles. This type of herpes causes chicken pox. It's slightly different then the herpes that causes cold sores and genital herpes. If you have had chicken pox as a child then you could possibly get shingles later in life.
It could be Ramsey-Hunt Syndrome. The "pain and rash" referred to is too general to determine exactly what is meant, but it could mean the condition known as shingles. This syndrome a combination of shingles from the reactivated herpes zoster virus (chickenpox) in an area near the Facial Nerve. The rash and blisters cause an inflammation of that nerve which then causes Bell's Palsy. Of course, "pain and rash" as the question puts it is so general in nature it can mean anything. Pain where? Rash where? What kind of pain? What kind of rash? If the "pain and rash" is something other than shingles, then it is not Ramsey-Hunt Syndrome. It becomes academic, however, because the palsy is still Bell's Palsy as long as it was caused by damage to the Facial Nerve and not some other damage. If the shingles did cause the BP, then treating the shingles with anti-viral medications may speed recovery from the shingles and once the shingles are gone, so will the source of the nerve inflammation. That means that facial muscle movement will most likely return.
The pain from shingles can cause a person's blood pressure to spike.
I would say that you can't reliably diagnose zoster (shingles) without the rash. Some specialists have coined the term "zoster sine herpete" for symptoms (usually pain) without any rash that they believe is due to the varicella virus (the cause of chicken pox and then shingles) but the existence of this has been difficult to establish and it is nearly impossible (some would say impossible) to diagnose in most clinical settings.
There is no cure for shingles. Shingles or "zoster" is caused by the reactivation of the chicken pox virus in our bodies. It can be treated with antiviral medications such as acyclovir or Valtrex. Steroids are used for severe cases to control symptoms of pain, but do not cure shingles.
Your friend most likely has shingles. It is caused by the varicella (or herpes) zoster virus. Initially, it causes chickenpox. Later in life, it may reactivate and cause shingles, which presents as a rash along a single dermatome, frequently preceded by burning or lancinating pain. The particular cocktail of medications you have asked about are fairly typical for a shingles outbreak. Acyclovir is an antiviral drug which may decrease the time of outbreak if taken before the rash occurs. Tegretol is an anti seizure medication used in this particular instance to help control the neuropathic pain associated with shingles. Prednisone can be taken to help decrease the inflammation and pain associated with shingles, although this is not a medication I have used frequently for shingles, as it may cause other side-effects and worsen diabetes.
