Shingles
Early treatment of herpes zoster, complications and pain that remains after the rash.
Shingles (herpes zoster) is the reawakening, years later, of a virus that stays "asleep" in the nerve roots of people who had chickenpox as children. On one side of the body, along a band, there is first pain, burning or tingling, then fluid-filled blisters on red skin.
Why the first 72 hours matter
Antiviral treatment works best when it starts within the first 72 hours after the rash appears: it speeds up healing and reduces pain. So if you see painful blisters on one side of your body, do not wait.
When to seek help urgently
- The rash is on the face, especially around the eye or on the tip of the nose
- The rash has spread to several areas of the body
- People with weakened immunity, pregnant women and older people
- Severe pain, high fever or general weakness
After healing
In some patients, especially older ones, the pain lasts for months after the rash: this is called postherpetic neuralgia. This pain can be treated too. A vaccine that prevents shingles exists for people over 50; discuss it with your doctor.
