Shingles, also known as herpes zoster, is a medical condition caused by the varicella-zoster virus. This is the same virus that causes chickenpox. After a person recovers from chickenpox, the virus can stay in their body in a dormant state. However, in some cases, the virus can become active again, usually many years later, and cause shingles.

Shingles typically presents as a painful rash that usually appears on one side of the body, often in a strip or band-like pattern. The rash may be accompanied by itching, tingling, or a sensation of burning. Blisters may also form on the rash and can take several weeks to heal.

Shingles can be quite uncomfortable and can cause significant pain and discomfort. It is most common in older adults and people who have weakened immune systems. If you suspect you have shingles, it is important to seek medical attention as soon as possible. Early treatment can help alleviate symptoms and prevent complications.
