Calluses and corns

Calluses and corns are areas of thick skin caused by pressure or friction. They may cause pain when a person walks or wears shoes.

Calluses usually form on the hands or feet. They may look gray or yellow and be less sensitive to the touch than surrounding skin. They often don't need treatment. Calluses on the hands usually can be prevented by wearing gloves to protect hands, such as when hammering or raking. Calluses on the feet can usually be prevented by wearing shoes that fit well.

Corns have an inner core that can be soft or hard. Soft corns are found between toes. Hard corns may form on the top of a toe. Corns caused by poorly fitting shoes will often go away with the right size shoe. Using protective padding to cushion the corn can help relieve pain while the toe heals.

Calluses and corns can be treated with over-the-counter callus-removing products, such as those that contain salicylic acid or urea. These products come in creams, ointments, gels, and patches. Sometimes a doctor will remove a callus or corn.

A person who has diabetes, peripheral arterial disease, peripheral neuropathy, or other conditions that cause circulatory problems or numbness should talk to a doctor before trying any treatment for calluses or corns.
