Corns and calluses are annoying and sometimes painful thickenings that form in the skin in areas of pressure.
Corns and calluses can be prevented by reducing or eliminating the circumstances that lead to increased pressure at specific points on the hands and feet.
Corns and calluses can be treated with many types of medicated products to chemically pare down the thickened, dead skin.
People with fragile skin or poor circulation in the feet (including many people with diabetes or peripheral arterial disease) should consult their health-care professional as soon as corns or calluses develop.
What are corns and calluses?
Corns and calluses are annoying and sometimes painful thickenings that form in the skin in areas of
excessive pressure. The medical term for the thickened skin that forms corns and calluses is
(plural=hyperkeratoses). 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, also known as helomas or clavi, sometimes have a dry, waxy, or translucent appearance.
Corns and calluses occur on parts of the feet and sometimes the fingers. Corns are often painful, even when they are small. Common locations for corns are
on the bottom of the foot (sole), over the metatarsal arch (the "ball" of the foot);
on the outside of the fifth (small or "pinky") toe, where it rubs against
between the fourth and fifth toes. Unlike other corns that
are firm and flesh-colored, corns between the toes are often whitish
and messy; they are sometimes called "soft corns" (heloma molles), in contrast to the more common "hard corns" (heloma durums) found in other locations.
Because we expose our feet to potential injury in our daily lives by walking, we have all experienced pains in the feet at one time or another. There are many common causes of foot pains, such as blisters and corns. There are also less common causes of foot pain, such as sciatica and osteomyelitis. Treatments for foot pain depend on the particular cause.
