How is shingles treated?

Shingles is a reactivation of the virus that causes chickenpox. It often produces burning or painful skin followed by grouped blisters in a band on one side of the body. Antiviral treatment can limit viral activity and is most useful when started early, so contact a clinician as soon as a one-sided painful rash or unexplained blisters appear.

Take prescribed antiviral medicine exactly as directed. Use the pain medicine recommended for you, and keep the rash clean, dry, and lightly covered with loose clothing or a non-stick dressing. Do not burst blisters or share towels, clothing, or dressings. Until the blisters have crusted, avoid close contact with pregnant people who are not immune to chickenpox, newborns, and people with weakened immunity. A shingles vaccination can help reduce future risk but does not treat an active rash.

Seek same-day medical advice for a rash near the eye or ear, facial weakness, confusion, severe headache, weakness in a limb, extensive blistering, or severe pain. Chest pain or breathing difficulty requires emergency care rather than assuming it is part of the rash. People with weakened immunity, pregnancy, or a rapidly worsening illness should seek prompt assessment.

Could this be shingles, and should I start an antiviral? What pain plan and skin covering are suitable, how long should I avoid vulnerable contacts, and when should I consider vaccination?
