Corns and calluses are your body’s response to friction or pressure against the skin. If your foot rubs inside your shoe, the affected are of skin thickens. Or if a bone is not in the normal position, skin caught between bone and shoe or bone and ground builds up. In either case, the outer layer of skin thickens to protect the foot from unusual pressure.

In many cases, corns and calluses look bad but are not harmful. However, more severe corns and calluses may become infected, destroy healthy tissue, or affect foot movement. But with your doctor’s help, corns and calluses can be controlled.

Note: Don’t attempt “home surgery” or over-the-counter “medicated pads” on corns or calluses. Doing so may damage healthy skin or cause an infection.
