Shingles is an infection of a nerve that causes a painful rash. It can occur in all ages, including children. It tends to more common as you get older.
If you've had chickenpox the virus stays in your body - this virus can trigger shingles in later life.
Shingles can be triggered by stress, certain conditions, or treatments like chemotherapy.
You can't catch shingles from someone else. However, you can catch chickenpox from someone with shingles if you have never had chickenpox before or are not immune.
