Symptoms and causes

A corn is also called clavus and is a painful callus on the foot sole or in between the toes. It forms as a consequence of pressure. Increased pressure on certain parts of the foot can be caused by ill-fitting shoes, but also by skeletal deformities or malposition of the feet.

Diagnosis and treatment

A diagnosis is made based on what the physician sees. Sometimes, a callus layer must be scraped off to distinguish it from a plantar wart.

The main thing to do for the treatment of a corn is to remove the pressure by, for example, using different footwear or providing orthotics. The callus kernel must also be removed, for which we can refer the patient to our medical pedicure service. A softening ointment can be used before a pedicure treatment.
