Acallusis a change in your skin that forms to protect an area subject to constant strain, friction, or pressure. It’s very common to develop calluses on hands or feet, but they can appear on other areas such as knees.

Summary
A callus is a dense, flat area of skin that hardens to protect an area subject to constant pressure or friction.
A callus can appear on any part of your body. It most often forms on the sides and soles of your feet and the palms of your hands. A callus can occur due to certain activities, such as gardening, weightlifting, or tennis, in which your hands or feet repeat an action that causes friction against a spot on your skin.
Conservative home therapies can often repair a callus. A podiatrist can shave down the callus if these options don’t work. The need for surgery, which is only necessary to shave or remove a bone structure that causes a callus to form, is rare.
