Hello,
Welcome to the ehealthforum and I am really glad to help you out. From your symptoms it looks like shingles. Shingles occurs in people who have had chickenpox and represents a reactivation of the dormant varicella-zoster virus.
The first sign is usually a tingling feeling, itchiness, or stabbing pain on the skin. After a few days, a rash appears as a band or patch of raised dots on the side of the trunk or face. The rash develops into small, fluid-filled blisters which begin to dry out and crust over within several days.
You need pain killers, antiviral drugs and steroids.
My sincere advice is to consult your doctor. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
