About Shingles (Herpes Zoster)
A shingle is a painful rash that develops on one side of the face or body. The rash consists of blisters that typically scab over in 7 to 10 days and fully clear up within 2 to 4 weeks. Before the rash appears, people often have pain, itching, or tingling in the area where it will develop. This may happen several days before the rash appears.
