(HealthDay News) -- Blisters are fluid-filled sacs on the skin that can be caused by friction from clothing or shoes, burns, or certain disorders and conditions.
The University of Virginia Health System offers these suggestions for how to take care of a blister and prevent infection:
- Gently wash the blister with soap and water.
- Apply an ice pack to reduce pain and swelling.
- Never burst or puncture the blister.
- If the blister bursts on its own, cover it with a bandage or dressing to keep it clean and dry.
- Check the blister frequently for signs of infection, which could include warmth, redness, swelling, drainage, pus or pain. If you have any of these signs, contact your doctor without delay.
