Managing blisters in competitive athletes.

Friction blisters can have a negative effect on an individual's ability to perform his or her sport or duties. In a recent study, 69% of soldiers participating in a 20-km road march were found to have blisters, 10% of whom required medical intervention. Blistering of the feet is one of the most common injuries sustained by runners while training and racing. Although most blisters are minor and can be treated conservatively, others can lead to intense pain, cellulitis, and even sepsis. The best way to treat friction blisters is to prevent them; however, if they do occur, timely and effective treatment will help prevent the complications that can impede athletic performance.
