Overview
Shingles is a painful, blistering rash caused by the reawakening of the chickenpox virus, which lies dormant in the nerves for years after a childhood infection. It appears as a band of blisters on one side of the body or face, often with burning pain. It is more common with age or a weak immune system. Early antiviral treatment eases it and reduces the risk of lingering nerve pain, so prompt care matters.
Symptoms
- Burning, tingling or pain in a band on one side of the body
- A red rash appearing a few days after the pain
- Fluid-filled blisters that crust over
- Sensitivity of the skin in the affected area
- Fever and tiredness in some people
When to see a doctor
See a doctor within a few days of the rash starting so antivirals can begin, and urgently if it affects the eye or forehead.
Emergency — call 108 or go to the nearest hospital
- Shingles rash near or in the eye, or with severe headache, confusion or widespread blisters — seek care urgently to protect sight and health
Causes
Reactivation of the varicella-zoster (chickenpox) virus, more likely with older age, stress and a weakened immune system.
