Shingles is a painful, blistering rash caused by reactivation of the chickenpox virus (varicella-zoster) that has stayed dormant in the nerves for years. It usually appears as a band on one side of the body.
Diagnosis is usually clinical (from the typical rash)
Swab of a blister (PCR) if the diagnosis is unclear
Treatment & management
Antiviral medicine started early (ideally within 72 hours) shortens the attack
Pain relief, including nerve-pain medicines for severe cases
Keeping the rash clean and dry, loose clothing
Cool compresses and calamine for itching
Vaccination can prevent shingles in older adults
When to see a doctor urgently
Shingles near or in the eye (can threaten sight — urgent)
A widespread rash or one in someone with weak immunity
Severe pain, or pain that persists after the rash heals
Signs of skin infection: spreading redness, pus or fever

Frequently asked questions
Is shingles contagious?
You cannot catch shingles from someone, but the fluid in the blisters can give chickenpox to a person who has never had it or been vaccinated. Keep the rash covered until it crusts over.
Why does shingles pain last so long?
The virus inflames the nerve, and some people get lasting nerve pain (post-herpetic neuralgia) after the rash heals. Starting antivirals early lowers this risk.
Can I get shingles more than once?
Yes, though most people get it only once. Vaccination is recommended for older adults to reduce the risk.
