Health Tip: Treating a Blister

Prevent infection with proper care

(HealthDay News) -- Blisters are sore, swollen areas on the skin where fluid has collected beneath an outer layer of skin. Blisters are caused by friction, often from poorly fitted shoes or socks that rub against the skin.

Here are suggestions on caring for a blister, courtesy of the University of Michigan Health System:

  • Steps should be taken to avoid further irritating the problem area.
  • Large blisters can be carefully drained with a sterilized needle, then covered with antibiotic ointment and a bandage.
  • For extra protection, purchase a moleskin at a drugstore. Cut a hole that's larger than the blister in the moleskin, creating a moleskin "donut." Then apply the moleskin so that the hole is over the blister.
  • See your doctor about any blisters that don't heal in a reasonable amount of time, or look like they may be infected.
