Pressure and repeated rubbing can cause a thickening of an area of skin on the foot. This is known as a callus. This protective layer of skin can vary in size and can become painful. A lower extremity medical professional can evaluate the cause of the callus and recommend the best treatment. Removing the callus without treating the cause may result in the callus reappearing.
“Most calluses gradually disappear when the friction or pressure that caused them is removed. However, a doctor may choose to shave the top of the callus to reduce the thickness.”
