What is a corn? What is a callus?

Corns and calluses are areas of thickened skin that develop to protect that area from irritation. They occur when something rubs against the foot repeatedly or causes excess pressure against part of the foot. The term callus commonly is used if the thickening of skin occurs on the bottom of the foot, and if thickening occurs on the top of the foot (or toe), it's called a corn..

What are the causes?

Corns often occur where a toe rubs against the interior of a shoe. Excessive pressure at the balls of the feet—common in women who regularly wear high heels—may cause calluses to develop on the balls of the feet. 

What are the symptoms?

Corns and calluses typically have a rough, dull appearance. They may be raised or rounded, and they can be hard to differentiate from warts. Corns or calluses sometimes cause pain.

When should you visit a podiatrist?

If corns or calluses are causing pain and discomfort or inhibiting your daily life in any way, see a podiatrist. Also, people with diabetes, poor circulation, or other serious illnesses should have their feet checked.
