Shingles. Shingles is an infection of a nerve area caused by the varicella-zoster virus. It causes pain and a rash along a band of skin supplied by the affected nerve. Symptoms usually go within 2-4 weeks. Pain sometimes persists after the rash has gone, more commonly in people over the age of 50. http://patient.info/health/shingles-herpes-zoster-leaflet.
Painful viral rash. Shingles is the name for a painful syndrome that usually has small blisters (vesicles) and occurs in a very specific, generally linear and one-sided pattern. It is caused by reactivation of the virus that causes chickenpox, varicella zoster. It is treatable, the sooner the better, so patients who think they have shingles should be seen promptly to minimize the risk for chronic pain.
