A corn or callus are areas of thickened skin that occur in areas of pressure. They are actually a normal and natural way for the body to protect itself. For example, callus develops on the hand when chopping a lot of wood – its a normal way for the skin to protect itself. In the foot, the skin will thicken up to protect itself when there are areas of high pressure. The problem occurs when the pressure continues, so the skin gets thicker. It eventually becomes painful and is treated as something foreign by the body.

Corns are hyperkeratosis of the skin. This thickening of the surface layer of the skin in response to pressure. Corns usually form on the toes, where the bone is prominent and presses the skin against the shoe, ground, or other bones. As corn becomes thick the tissues under the corn are subject to increased irritation. There may be a deep seated nucleation, this is like a core where the corn is thickest and most painful. As corns become inflamed, there is pain and sometimes swelling and redness. Common places where corns form are; the top surface of the toe, at the tip of the toe, and between the toes.
