After you have had chickenpox, you are not likely to get it again. But the virus stays in your body long after you get over the illness. If the virus becomes active again, it can cause a painful viral infection called shingles. Shingles is is a viral infection that may cause pain, burning, or a tingling sensation on either the left or right side of the body. Several days or weeks later, a band, strip, or small area of rash usually appears in the same area and progresses into blisters, which scab over before clearing up over the next few weeks.
