Health Tip: Caring for a Blister

(HealthDay News) -- Blisters form when something presses and rubs on the skin. While you should monitor the area for signs of infection, such as pain or redness, experts say the best way to care for a blister is to leave it alone.

The University of Michigan Health System offers these suggestions:

  • Avoid popping a blister. But if it is large or a source of constant pain or discomfort, use a sterile needle and carefully drain it.

  • Don't cover the blister unless you have to. If something is rubbing against the area, cover it with a loose bandage, which should be changed regularly.

  • If possible, avoid the activity that caused the blister to form.

  • Always wash your hands carefully before touching a blister.

  • Apply an antibiotic ointment to help prevent infection.
