Corns And Calluses can be annoying, but your body actually forms them in areas of excessive pressure to protect sensitive skin. Corns And Calluses are often confused with one another.
Corns generally occur on the tops and sides of the feet. A hard corn is a small patch of thickened, dead skin with a central core. A soft corn has a much thinner surface and usually occurs between the 4th and 5th toes. A seed corn is a tiny, discrete callous that can be very tender if it's 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 plugged sweat ducts.
Calluses can develop anywhere there is repeated friction. Like corns, calluses have several variants. The common callus usually occurs when there's been a lot of rubbing against the hands or feet. A plantar callus is found on the bottom of the foot.
