Symptoms
- Burning, tingling, or shooting pain in a band on one side of the body — often precedes rash by 2–3 days
- Red rash appearing in a stripe pattern (dermatome) — never crosses the midline
- Fluid-filled blisters that crust over within 7–10 days
- Fever, headache, fatigue
Antiviral Treatment
| Timing | Action |
|---|---|
| Within 72 hours of rash onset | Antivirals (aciclovir, valaciclovir) significantly reduce severity and duration |
| After 72 hours | Still may be given, especially if new blisters still forming or high risk of complications |
| Pain relief | Paracetamol, NSAIDs; gabapentin/amitriptyline if nerve pain severe |
Postherpetic Neuralgia (PHN)
PHN is persistent nerve pain lasting more than 90 days after the rash has healed. It affects 10–18% of people with shingles, and risk increases significantly with age (up to 50% in those over 70). Early antiviral treatment reduces PHN risk.Shingles Near the Eye — EmergencyShingles affecting the tip of the nose, forehead, or around the eye (ophthalmic shingles) can threaten vision and requires urgent same-day ophthalmology assessment. Do not delay treatment.
Contagious RiskShingles cannot be 'caught' as shingles, but the fluid in blisters can transmit chickenpox to anyone who hasn't had it or been vaccinated. Cover the rash and avoid contact with pregnant women, newborns, and immunocompromised people until blisters crust.
Can I get shingles more than once?
Yes, though it's uncommon — most people get it only once. Recurrence is more likely in people who are immunocompromised.
Should I get the shingles vaccine?
The Shingrix vaccine is recommended for adults 50+ in the US and being rolled out in the UK for those 65+ (and immunocompromised from 50). It's over 90% effective at preventing shingles and PHN.
What triggers shingles reactivation?
Stress, illness, ageing immune system, immunosuppressive medications, and other illnesses that weaken immunity. Often there's no identifiable trigger.
