Corns are a build up of hard skin, usually in relation to excessive pressure or friction. They can sometimes be very painful. Removal of the corn is simple, with debridement of the corn and surrounding hard skin, done quickly and safely with a sterile blade. Corn removal does not hurt, as the hardened skin tissue has no sensation. Sometimes changes to footwear may be required to prevent a corn from returning, or insoles placed into shoes to re-distribute plantar pressures away from the area where the corn is developing.
