Corns are a common example of avoidable foot pain. Corns often occur on the top of the toes where there is pressure from the shoes. Corns, also called helomas, are thickened areas of skin that form in response to excessive pressure and friction. They form to protect the skin and the structures beneath it from damage or injury. Corns are usually hard and circular, with a waxy or translucent center. They may become painful or ulcerated in response to persistent friction. Certain corns may become entwined with the nerves of the skin, these corns are particularly painful. Corns can be very painful, especially if there is inflammation and swelling around the corn. There are two types of corns. Hard corns (heloma durums) are the most common type.
