What are the treatments for blisters?

Blisters will usually heal on their own. The skin over the blister helps keep out infections. You can put a bandage on the blister to keep it clean. Make sure that there is no more rubbing or friction on the blister.

You should contact your health care provider if

  • The blister looks infected - if it is draining pus, or the area around the blister is red, swollen, warm, or very painful
  • You have a fever
  • You have several blisters, especially if you cannot figure out what is causing them
  • You have health problems such as circulation problems or diabetes

Normally you don't want to drain a blister, because of the risk of infection. But if a blister is large, painful, or looks like it will pop on its own, you can drain the fluid.
