What are corns & calluses?
Corns and calluses, like warts, are excessive growths of skin. They differ from warts though because they are caused by pressure or friction on the foot, rather than by a contagious virus.
Like warts and verrucas, when corns and calluses appear on weight-bearing areas such as the ball of the foot, the pressure on the underlying skin layers caused by the thickened area of skin can make them particularly uncomfortable and quite painful to walk on.
What causes corns & calluses?
The most common cause of corns and calluses is shoes that don’t fit. Children are the most vulnerable to this because of the rapid growth of their feet.
Things to know about corns & calluses.
Corns and calluses may go away by themselves eventually, if the pressure or friction on the foot is removed, but this can take quite a while. A corn or callus will almost certainly return, if the pressure or friction comes back too.
