Famvir for Shingles
Shingles (also known as herpes zoster) is caused by a virus (the varicella-zoster virus). It is the same virus that causes chickenpox. Most people are infected with this virus (as chickenpox) when they are children. The body never completely gets rid of the virus, and the virus remains inactive in certain nerve cells in the body. Later in life, often triggered by stress or illness, the virus can become active again, causing shingles.
Symptoms of shingles may include a rash (usually on only one side of the body) and burning or tingling pain. Usually, the rash forms blisters that may break and ooze. If this happens, you may be able to spread the "shingles virus" to people who have never had chickenpox. Shingles pain can be very severe. It can continue long after the rash is gone (known medically as postherpetic neuralgia).
