Shingles (herpes zoster) is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chickenpox the varicella-zoster virus. Antiviral drugs may also help stave off the painful after-effects of shingles known as postherpetic neuralgia. Shingles is a very painful disease caused by the same herpes virus that causes chickenpox (varicella zoster virus). Like other herpes viruses, the varicella-zoster virus has an initial infectious stage (chickenpox) followed by a dormant stage. The patch, called Lidoderm, provides pain relief for some people with shingles. The former is caused by the Varicella zoster virus, which is associated with Herpes zoster, the virus responsible for shingles. About 20 percent pf of shingles cases may result to a condition called post-herpetic neuralgia (PHN), where pain may last from 30 days to even years after the rash has healed.
