Patient/caregiver was educated on pathophysiology of callus as follows:
- Callus is a portion of thickened skin developed especially in response to prolonged excessive friction and pressure on the skin against any hard surface.
- The sensitive skin can respond to prolonged friction and pressure with development of a callus.
- Callus can present as a thick, hardened, & raised area of skin and is usually painless. Callus carries the risk of being infected by bacteria, with foul smelling drainage.
- Since feet stay in contact against the hard surface of ground and experience lot of friction during ambulation, calluses are more likely to occur on the plantar surface of feet and toes.
- Calluses are also more likely to happen on the palm and fingers, especially in individuals performing manual labor.
