Shingles is caused by the reactivation of the chickenpox virus and can appear years after the original infection. Early symptoms may include burning, tingling, pain, or sensitive skin before a rash develops.
The rash usually appears on one side of the body. Starting antiviral treatment within 72 hours can help reduce symptoms and complications. Recognizing the signs early, along with vaccination and a strong immune system, can lower the risk of serious effects.
