What is Shingles?
Shingles (herpes zoster virus) is a painful viral infection of the nerve roots. The virus moves along the nerve fibers and affects cells of the skin, resulting in a skin rash. Caused by the same virus behind childhood chickenpox, the virus is never fully cleared from the body and shingles occurs when the virus reactivates.
