Corns & Calluses
A “corn” is a small circular thickened lesion in the skin of the foot. It usually forms due to repeated pressure on the skin, such as the rubbing of a shoe. The name “corn” comes from its resemblance to a kernel of corn. A corn is different from a callus in that it has a central core of hard material. People with foot deformities, such as hammertoes, often suffer from corns because the tops of the bent toes rub against the tops of shoes.
A “callus” is a thickened area of skin on the foot caused by pressure and repeated rubbing, such as from a shoe or sock. The rubbing causes the skin to produce a layer of protective skin (a callus). Calluses vary in size, and can become painful.
There are a number of treatments for painful calluses and corns. Your podiatrist can evaluate the cause of your corn or callus and recommend the treatment most appropriate for your condition. However, if the underlying cause of the callus is not treated or removed, the callus may return.
While treatment for calluses and corns is not always necessary, it may provide you with more comfort. Larger calluses can cause significant pain. In some patients, especially when they become cracked, calluses can lead to wounds that may lead to serious problems, especially in people with diabetes.
