Corns and calluses are hard, thickened areas of skin that form as a consequence of rubbing, friction or pressure on the skin. Corns and calluses both form on the feet and can make walking painful.
Corns and calluses conditions:
Corns generally occur on the tops and sides of the toes.
Hard corn = small patch of thickened, dead skin with a small plug of skin in the centre.
Soft corn = has a much thinner surface, appears whitish and rubbery, and usually occurs between the toes.
Seed corns = clusters of tiny corns that can be very tender if they are on a weight-bearing part of the foot. Seed corns tend to occur on the bottom of the feet, and some doctors believe this condition is caused by blocked sweat ducts.
Calluses are hard and rough-feeling areas of skin that can develop on hands, feet or anywhere there is repeated friction - even on a violinist's chin.
Common callus = usually occurs when there has been a lot of rubbing against the hands or feet.
Plantar callus = usually found on the bottom of the foot.
