Definition. Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso. Shingles is caused by the varicella-zoster virus â the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles. While it isn't a life-threatening condition, shingles can be very painful.
Shingles (herpes zoster) occurs when the dormant chickenpox virus (varicella-zoster) is reactivated in your nerve tissues. Early signs of shingles include tingling and localized pain.Most, but not all, people with shingles develop a blistering rash.arly symptoms of shingles may include fever and general weakness. You may also feel areas of pain, burning, or a tingling sensation. A few days later, the first signs of rash appear. You may begin to notice pink or red blotchy patches on one side of your body. These patches cluster along nerve pathways.
