A callus is an area of thickened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on feet because of frequent walking and poorly fitting footwear. While they can be perceived as being unsightly, calluses are generally not harmful, but if neglected for long periods may sometimes lead to other problems, such as a skin ulceration or infectionor cause the sufferer to try and offload the affected painful area, which can place excessive stress on the asymptomatic side.
The formation of calluses is caused by an accumulation of dead skin cells that harden and thicken over an area of the foot. Some calluses have a deep seated core known as a nucleation. This particular type of callus can be especially painful to pressure.
Calluses are a build-up of hard skin and are generally found beneath the weight bearing surfaces on the bottom of the foot. Some degree of callus formation on the sole of the foot of an active person is normal and generally does not cause any problems for a patient. Callus formation can also occur around the periphery of the heels, which can lead to fissuring of the callus, which can become quite painful.
Corns and calluses are thick, hardened layers of skin that develop when your skin tries to protect itself against friction and pressure. They most often develop on the feet and toes or hands and fingers. Corns and calluses can be unsightly. If you're healthy, you need treatment for corns and calluses only if they cause discomfort.
