Corns: Symptoms & Signs

Corns are, like calluses, areas of thickened skin, medically known as hyperkeratosis. Corns typically occur on the feet and occasionally on the fingers. It's possible to prevent corns and calluses by reducing or eliminating the conditions, such as poorly fitting footwear, that lead to increased pressure at specific points on the feet.

Signs and symptoms of corns include a

• thick, rough area of skin with a hardened, raised bump;
• tenderness or pain under the skin; and
• flaky, dry, or waxy skin.

A callus refers to a more diffuse, flattened area of thick skin, while a corn is a thick, localized area that usually has a popular, conical, or circular shape. Corns may sometimes be painful.

Cause of corns

The cause of corns and calluses is excessive, repeated pressure or friction on the affected area.
