What is a callus?
Calluses are thickenings of the outermost layer of the skin. They're painless. They can form on hands, feet, or anywhere there is repeated friction -- even on a violinist's chin. There are different types of calluses. The common callus usually happens when there's been a lot of rubbing against the hands or feet. A plantar callus is found on the bottom of the foot.
