Callus

A callus is an area of thick, hardened skin that forms in response to repeated friction, pressure, or other irritation. It is commonly found on the hands and feet, and can also form on the elbows and knees. Calluses are usually painless and do not typically require medical attention. However, if they become excessively thick, they can cause pain or difficulty moving the affected area. In such cases, a doctor may recommend treatments to reduce the callus. These may include filing down the callus with a pumice stone, soaking the area in warm water, or applying a softening ointment.
