Blisters
A blister is a small pocket of fluid within the upper layers of the skin (between dermis and epidermis ), typically caused by forceful rubbing (friction)or burning. An irritated red skin is the first sign. The most common cause is a poor fitting shoe combined with an activity that creates excessive friction on a certain part of the foot. Generally the size and location of the blisters will determine the amount of pain.
Blisters are the most common sports injury. The pain can severely interrupt the performance of an athlete — distance runners, hikers, hunters and non-
athletes alike. The most frequent protocol is after-care: treating a blister for days following activity to promote healing and protect against continued skin damage.
