Corns And Calluses
A corn is a painful thickening (bump) of the outer skin layer, usually over bony areas such as toe joints.
A Calluses is a painless (usually) thickening of skin caused by repeated pressure or irritation. Corns and calluses form to protect a skin area from injury caused by repeated irritation (rubbing or squeezing). Pressure causes cells in the irritated area to grow at a faster rate, leading to overgrowth. They are a frequent problem for all athletes.
Types of calluses
A plantar callus, a callus that occurs on the sole of the foot, has a white center. Hereditary calluses develop where there is no apparent friction, run in families, and occur most often in children.
Repeated injury to the skin, particularly on the feet. These occur frequently in athletes due to excessive perspiration, increased heat, friction of clothing and protective gear, or poorly fitting shoes. Athletic activities that cause pressure on the hands or knees include throwing sports, gripping sports and wrestling.
The thickening of the skin is a protective reaction. For example, farmers and rowers get callused hands that prevent them from getting painful blisters. People with bunions often develop a callus over the bunion because it rubs against the shoe.
Neither corns nor calluses are serious conditions.
Signs and symptoms
If a corn persists or becomes painful despite self-care, several treatments can provide relief. Your doctor can pare down a large corn with a scalpel, usually during an office visit. Your doctor may also suggest applying an antibiotic ointment to reduce the risk of infection.
