Shingles

Key Points

Overview

Shingles is a viral infection that causes a painful rash, often appearing as blotches on one side of the body. It is caused by the varicella-zoster virus, the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains inactive in nerve tissue near the spinal cord and brain. It can reactivate years later, causing shingles, especially when the immune system is weakened due to stress, illness, or certain treatments. Early medical advice from a pharmacist or doctor is crucial, especially within three days of the rash appearing. Treatment often involves antiviral medicines to speed recovery and manage symptoms, along with pain relief and self-care measures.
