Corns, technically known as clavi, are thick, hardened layers of skin that develop when your skin tried to protect itself against friction and pressure. They most often develop on the feet and toes or hands and fingers. Corns can be unsightly but only require treatment if they cause discomfort. For most people, simply eliminating the source of friction or pressure makes corns disappear. However, if you have diabetes or another condition that causes poor circulation to your feet, you’re at greater risk of complications from corns. Our providers at Sand Lake Dermatology Center can help you manage and treat your corns if you have one of these conditions. While corns can occur at any age, they are most often seen in older patients.
