Shingles (herpes zoster) causes pain and a blistered rash. The rash can appear anywhere on the body but will be on only one side of the body, the left or right. It will be in a band, a strip, or a small area. The pain can be very severe. Shingles can also cause tingling or itching in the area of the rash. The blisters scab over after a few days and heal in 2 to 4 weeks. Medicines can help you feel better and may help prevent more serious problems caused by shingles.
Shingles is caused by the same virus that causes chickenpox. When you have chickenpox, the virus gets into your nerve roots and stays there (becomes dormant) long after you get over the chickenpox. If the virus becomes active again, it can cause shingles.
