What to do if…
you develop a new painful blistering rash in a band on one side of your body

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

This could be shingles or another condition. Arrange prompt same-day medical assessment. A rash anywhere on your face or near your eye needs urgent in-person assessment today.

Do not do these things

  • Do not wait several days before seeking care for a new painful, blistering, one-sided rash.
  • Do not scratch, pick, or pop the blisters.
  • Do not leave the rash uncovered around other people if you can cover it comfortably.
  • Avoid contact until the rash has scabbed over with pregnant people who have not had chickenpox or the chickenpox vaccine, premature or low-birth-weight infants, and people with weakened immune systems.

What to do now

  1. Arrange prompt same-day medical assessment.
    Contact your doctor, use urgent care, or use telehealth to help arrange the right assessment. Say: “I have a new painful blistering rash in a band on one side of my body. The pain or tingling started [time/date], and the rash started [time/date].” If this is shingles, antiviral medicines work best when started as soon as possible, often within 3 days after the rash appears.

  2. Treat any rash on your face as urgent.
    Seek urgent in-person medical care today if the rash is anywhere on your face, including your forehead, eyelid, around your eye, or on your nose. Seek emergency care now if you have a red or painful eye, light sensitivity, blurred vision, other vision changes, confusion, rapidly worsening symptoms, or feel seriously unwell.

  3. Gently clean and cover the rash.
    Gently wash the rash and cover it with loose clothing or a sterile non-stick bandage if you can do so comfortably. Wash your hands after touching the rash or changing a dressing.

  4. Reduce the chance of spreading the virus.
    Active shingles lesions can spread the virus that causes chickenpox until the rash has scabbed over. Covering the rash, avoiding touching or scratching it, washing your hands, and avoiding contact with higher-risk people can lower the risk.

  5. Record the timing and appearance.
    Take clear photos of the rash, including a close-up and a wider view. Note when the pain, burning, itching, or tingling started and when the blisters appeared.

  6. Ask about pain relief that is safe for you.
    Ask a pharmacist or clinician about over-the-counter pain relief that is suitable for you, and follow the label. A clean, cool, damp washcloth may reduce discomfort.

  7. Flag higher-risk situations when you contact a clinician.
    Tell them promptly if you are pregnant, have a weakened immune system, take medicines that suppress your immune system, have a widespread rash, or feel significantly unwell.

What can wait

  • You do not need to prove what the rash is before seeking care.
  • You do not need to make decisions about work or school before you have been assessed and asked about precautions.
  • You do not need major cleaning. Focus on covering the rash, washing your hands, and avoiding contact with higher-risk people.

Important reassurance

A painful, one-sided band of blisters is a recognised shingles pattern, but other causes are possible. Getting assessed promptly is a sensible next step.

Scope note

These are first steps for the next few hours. Medication choices, follow-up, and advice about work, school, or close contact may need help from a clinician.

Important note

This is general information. It is not a diagnosis and is not legal, medical, financial, therapeutic, or other professional advice. Seek emergency care now for vision changes, a red or painful eye, confusion, rapidly worsening symptoms, or if you feel seriously unwell.
