Shingles is a reactivation of the chickenpox virus and typically occurs after the age of 50. It usually affects a specific area of the body, such as the torso, and individuals commonly experience one episode in their lifetime. Unlike herpes, shingles does not transmit shingles itself but the chickenpox virus. Shingles typically causes a significant burning sensation before the appearance of blisters. If you have concerns about small red bumps on your skin, you can visit a pharmacy to have a pharmacist evaluate them in person.
