Shingles (Herpes Zoster)

What is shingles?

Shingles, or herpes zoster, is a common viral infection of the nerves, which results in a painful rash or small blisters on an area of skin anywhere on the body. Burning or shooting pain and tingling or itching are early signs of the infedtion, usually located on one side of the body or face. Even after the rash is gone, the pain can continue for months, even years.

Shingles is caused by the reactivation of the varicella-zoster virus, which causes chickenpox. After a person has had chickenpox, the virus lies dormant in certain nerves for many years. Herpes zoster is more common in people with a depressed immune system, and in people over the age of 50.
