Callus in Child

A callus is a thickening of the skin that occurs in response to repeated shear or friction forces. Calluses are similar to corns, but calluses occur when abnormal forces are exerted over a larger area. Certain deformities of the feet, such as crookedness of the toes, may predispose one to the development of calluses. Calluses may cause pain, typically a burning sensation. Excessive weight-bearing and certain types of shoes are often contributing factors.
