What is a Corn? What is a Callus?

Corns and calluses are areas of thickened skin that develop to protect that area from irritation. They occur when something rubs against the foot repeatedly or causes excess pressure against part of the foot. The term callus commonly is used if the thickening of skin occurs on the bottom of the foot, and if thickening occurs on the top of the foot (or toe), it’s called a corn. sin embargo, the location of the thickened skin is less important than the pattern of thickening: flat, widespread skin thickening indicates a callus, and skin lesions that are thicker or deeper indicate a corn.

Corns and calluses are not contagious but may become painful if they get too thick. In people with diabetes or decreased circulation, they can lead to more serious foot problems.
