Corns and Calluses
Corns and calluses are thick, hardened layers of skin that develop when the skin tries to protect itself against friction or pressure. They often form on feet and toes and can also appear on hands and fingers.
You don't always require treatment for corns and calluses unless they cause pain or you don't like how they look. For many, simply removing the source of the friction or pressure makes them disappear.
Corns
Corns are smaller and deeper than calluses and have a hard center surrounded by swollen skin. They can be painful when pressed. Hard corns often form on the top of the toes or the outer edge of the small toe. Soft corns tend to form between the toes.
NOTE: If you have diabetes or another condition that causes poor blood flow to your feet, you're at greater risk of complications from corns and calluses.
Calluses
Calluses are rarely painful and tend to develop on pressure spots, such as the heels, the balls of the feet, the palms and the knees. They may vary in size and shape and are often larger than corns.
