Decades after childhood chickenpox, the herpes zoster virus that caused it could re-emerge as shingles. The virus can settle into nerve cells and, years later, be reactivated by various factors including age, stress, illness or medications. Shingles produces a painful rash and blisters, often on the chest or back.
Like any virus, shingles has to run its course. Fortunately, there are prescription medications that, if taken early enough, may shorten the duration of the infection and could reduce the risk of long-term complications. At the first sign of shingles, contact your doctor.
The June issue of Mayo Clinic Health Letter details these signs and symptoms:* Pain, burning, tingling or itching in a localized area that last one to three days, often before the rash appears* A painful red rash with blisters * Fever* Headache
Shingles blisters carry the chickenpox virus. Until the crustiness and scabbing disappear, people with shingles risk exposing others who have never had chickenpox.
