Thick, hardened layers of skin caused by friction and pressure.

Corns most often develop on the tops and sides of feet and between the toes. They can also be found in weight-bearing areas.

Corns are benign hardened, raised bumps surrounded by inflamed skin. They can be painful when pressed.

Self-care measures include wearing properly fitting shoes and using protective pads. Medicated patches can help remove corns, or a healthcare professional can trim them.
