Rashes are not to be taken lightly. If you ever have a concern about a rash, don't hesitate to call your doctor for advice. As annoying as corns and calluses can be, they actually form to protect the skin. They are very common and usually do not cause a problem, unless they build up or crack open, which can be painful. Corns usually show up on the feet, as areas of thick, hard, dead skin on the tops or sides of toe joints, or between the toes.
Calluses develop on the hands, feet or anywhere friction occurs repeatedly.
You'll notice patches of rough, thick, dead skin on the soles of the feet, the palms of the hands or any other area subject to friction. Most corns and calluses on the feet are caused by ill-fitting shoes. They put too much pressure on the toes. If you have a corn on a toe, place a corn pad on the toe to help ease the pressure. Rub it lightly with a pumice stone and apply a moisturizing lotion or hydrocortisone cream.
