Shingles, or herpes zoster, is a common infection of the nerves. It is caused by a virus. Shingles triggers a painful rash or small blisters on an area of skin. It can appear anywhere on the body, but it typically appears on only one side of the face or body - the right or left. Burning or shooting pain and tingling or itching are early signs of the infection. Even after the rash is gone, the pain can continue for months, even years. https://www.hopkinsmedicine.org/health/conditions-and-diseases/shingles
