When Is a Sunburn Bad?

If the sunburn covers a large area of the body or you're feeling pain or getting blisters over large areas, you should consult a medical professional. Blistering is common following sunburn, and these can be painful. Most will break by themselves and if possible, you should let them, rather than pop them deliberately.

When should I be concerned about my sunburn?

The sunburn is severe — with blisters — and covers a large portion of your body. The sunburn is accompanied by a high fever, headache, severe pain, dehydration, confusion, nausea or chills. You've developed a skin infection, indicated by swelling, pus or red streaks leading from the blister.

How do you know if your sunburn is bad?

See your doctor if the sunburn:
  1. Is blistering and covers a large portion of your body.
  2. Develops blisters on the face, hands or genitals.
  3. Is causing severe swelling.
  4. Shows signs of infection, such as pain, pus or red streaks leading away from an open blister.
  5. Doesn't improve within a few days.
