Corns occur when areas of the skin harden or thicken into an uncomfortable, often mildly painful, mass. Although they are rarely serious, they are unsightly and cause discomfort. Corns typically develop on the hands, toes, and feet, as the body attempts to protect itself from increased pressure and/or friction. Usually, corns are fairly simple to treat, but those with poor blood flow to the feet are at a greater risk of complications.
Information. Corns are the result of pressure or intense, regular rubbing of the skin. Though they can form anywhere, they are most common on the feet due to wearing uncomfortable or ill-fitting shoes, failing to wear socks with shoes, regularly wearing high heels, doing a job that requires a lot of standing or being on foot, and/or engaging in regular heavy lifting.
