Corns and calluses are thick layers of compressed dead skin cells that develop to protect the skin. They are caused by repeated friction against bony areas of the foot, or from shoes rubbing against the skin. Calluses form on the bottoms, or soles of the foot, and corns on the toes.
The pain or burning from the friction and pressure against the skin can be alleviated by padding the affected areas, or by using moleskin. Never cut corns or calluses, and never use home remedies without a podiatrist’s instructions.
