The virus lives in nerves near the spine. Activated virus travels along the nerves to the skin. It then causes a rash on the skin in groups or bands at the nerve endings. The rash usually stays as a band going across part of the body on one side. However, there are cases where the rash occur anywhere. For example, shingles on the face can involve the eyes, which is serious and can cause scarring and blindness.

Early symptoms are mild itching, tingling, pain, headache, fever, or flulike syndrome. As the condition progress, the rash start to appear. They consist of many small, fluid-filled blisters in groups that dry, scab over, and heal (like chickenpox) in a few weeks. Despite how itchy it is, you should avoid scratching at all cost. Scratching the rash can get a bacterial infection.

You might experience an amount of pain with the rash. A few people, especially those older than 50, can have pain (called postherpetic neuralgia) for more than 30 days. It can be very severe and interfere with daily activity.
