A callus is an area of hard, thickened skin on the foot that forms in response to pressure or friction, usually through poor-fitting shoes. When pressure is concentrated in a small area, a corn, which has a central core, may develop. If the pressure is not relieved, calluses and corns can become painful.
Common sites of corns and calluses are the ball of the foot, under the big toe, tips of toes and any bony prominence. ‘Soft’ corns may develop between the toes, where the skin is moist from sweat or inadequate drying. Sometimes, the pressure of the corn or callus may cause inflammation, which can result in pain, swelling and redness.
Symptoms of corns and calluses
Treatment for corns and calluses
Treatment of corns require removal of the dead tissue with a scalpel. The treatment of corns is often limited to one episode only. However, if the corn is large, in a difficult area or has been there for years (ie: is a chronic corn), there may need further treatments to get resolution. A follow up visit in 6 weeks after the initial treatment is usually highly recommended to resolve the issue.
