Shingles is a painful rash caused by the same virus that causes chickenpox. If you've had chickenpox, the virus stays dormant in your nerve cells for life. Years or decades later, it can reactivate and cause shingles. The rash typically appears as a band or stripe of blisters on one side of your body, often on the torso, face, or neck. Most people get shingles only once, though it can happen more than once.

These articles explain how doctors recognize shingles, what causes it to develop, and what treatment options exist. You'll find information about the symptoms to watch for, how the condition is diagnosed, pain management during recovery, and ways to reduce your risk of getting shingles in the first place.
