Shingles is a disease that affects your nerves. It can cause burning, shooting pain, tingling, and/or itching, as well as a rash and blisters.
You may recall having chickenpox as a child. Shingles is caused by the same virus. After you recover from chickenpox, the virus continues to live in some of your nerve cells. It is usually inactive, so you don’t even know it’s there, and most adults with the leftover virus in their bodies never get shingles.
But, for about one in three adults, the virus will become active again. Instead of causing another case of chickenpox, it produces shingles. We do not totally understand what makes the virus go from inactive to active.
