Shingles is a painful rash that usually develops on one side of the body, often the face or torso. The rash consists of blisters that typically scab over in 7 to 10 days and clears up within 2 to 4 weeks. Some people describe the pain as an intense burning sensation. For some people, the pain can last for months or even years after the rash goes away. This long-lasting pain is called postherpetic neuralgia (PHN), and it is the most common complication of shingles. Your risk of getting shingles and PHN increases as you get older.
