Friction blisters are a common annoyance for virtually all active pati
ents at every level-from weekend warriors to professional athletes. Wh
ereas small friction blisters are usually self-limited and amenable to
conservative treatment, larger ones generally respond better when the
y are first aseptically drained. Proper care of the blister site will
ward off infection, a possible complication of both spontaneous ruptur
e and therapeutic draining. Properly fitted shoes, socks, and athletic
equipment, together with the judicious use of lubricants, can help pr
event the formation of friction blisters.
