These two skin lesions are very similar in makeup, the difference being that a corn has a central core of firmer consistency. Both corns and calluses form in response to pressure or friction.
If someone has a hammertoe, shoe pressure on the top of the toe can cause a corn or callus. Shoe pressure along the sides of the forefoot can cause calluses. With lack of proper support or abnormal foot function, the shearing forces in the shoes can cause calluses.
Treatment options for the two conditions are similar, with the main goal being to first determine the cause and to then choose a treatment plan based on that cause. Simply paring down the corn or callus often provides symptomatic relief. If a deformity such as a hammertoe is present, the toe can be straightened to eliminate the cause of the corn.
A podiatrist has the necessary instruments to treat this common foot problem.
