Shingles

Shingles (herpes zoster) is a painful, blistering rash caused by the same virus that causes chickenpox. After you have chickenpox, the virus stays quietly in nerve roots for life — and can reactivate years or decades later as shingles, usually on one side of the body.

Who gets it

• Anyone who has had chickenpox can get shingles.
• Risk rises sharply after age 50.
• Higher risk with a weakened immune system — diabetes, HIV, chemotherapy, long-term steroid use, stress.
• One episode doesn't always protect you from another — recurrences happen.

Symptoms

• First, a burning, tingling or sharp pain in an area of skin — sometimes for a day or two before anything is visible.
• Then a red, blistering rash appears, typically in a band on one side of the body (chest, back, face or abdomen).
• Fluid-filled blisters crust over within a week.
• The rash heals in 2-4 weeks.
• General tiredness, headache, mild fever.

Why seeing a Health Expert quickly matters

• Antiviral medicines work best when started in the first 72 hours — they reduce severity, duration and the risk of lingering nerve pain.
• Shingles affecting the eye (around the forehead and nose) can cause vision loss — urgent eye review needed.
• Shingles around the ear can cause facial weakness and hearing loss (Ramsay Hunt syndrome).
• Any shingles in a person with weak immunity, pregnancy, or in children needs urgent attention.

The pain that can linger — postherpetic neuralgia

In some people — particularly over 60 — nerve pain continues for weeks or months after the rash heals. It can be severe. Specific nerve-pain medicines help; early antiviral treatment reduces the chance of this happening.

Care at home

• Keep the rash clean and dry; cover with a loose dressing.
• Simple pain relievers for the pain.
• Avoid contact with pregnant women, newborns, and people with weak immunity until the blisters crust over — you can spread chickenpox to someone who's never had it.
• Cool compresses for itching.

Vaccine

A shingles vaccine is available in India, recommended for adults over 50 — especially those with diabetes or weakened immunity. It substantially reduces the risk of shingles and of postherpetic neuralgia. Cost is not trivial; discuss with a Health Expert if it's worthwhile for you.
