Corns

Corns

Corns and calluses are areas of thick skin that result form excessive pressure or friction over a boney prominence. When these areas develop on the bottom of the foot they are called calluses. When they occur on the top of the toes they are called corns. They can also occur between the toes, the back of the heels and the top of the foot. The thickening of the skin is a normal body response to pressure or friction. Often times they are associated with a projection of bone called a bone spur. Not all areas of thickened skin are corns or calluses. Planter warts, inclusion cysts and porokeratoses also cause a discreet thickening of the skin that resembles corns and calluses.

Calluses

The most common area for the formation of calluses on the bottom of the foot is in the area of the ball of the foot. This is a weight bearing area where the long bones behind the toes called metatarsals, bear the greatest amount of weight and pressure. If one or more of these long bones (metatarsals) is out of alignment then excessive pressure is generated in the area producing a callous. The callused area can be very discreet and have a "core" or they can be more dispersed covering a larger area. These areas can become quite painful as the skin thickens. People who have diabetes are at risk of these areas breaking down producing sores or ulcerations that can become infected. People with diabetes should not try home remedies and should see a doctor for the treatment.
