Identification
-
In a foot corn callus, a small section of tough skin forms a lump and is surrounded by a larger area of tough skin somewhere on your foot. The smaller section is the corn, and the larger section is the callus.
Causes
-
Foot corn calluses are caused by friction. The most common source is ill-fitting shoes, but foot abnormalities or the way you walk can also cause foot corn calluses, according to EPodiatry.com.

Symptoms
-
In addition to the appearance of the foot corn callus itself, the skin in the area of the callus may feel tender, and it is possible to experience pain when you press down on the corn. The skin around the foot corn callus often becomes flaky, waxy or dry.
Risks
-
In patients with diabetes, a foot corn callus poses a danger for the formation of an open sore that is difficult to treat and prone to infection.
Treatment
-
If your foot corn callus causes pain, your doctor may be able to trim the affected skin or treat the area with salicylic acid or antibiotics. When foot corn calluses recur because of a deformity of the foot, surgery may be necessary to realign the bones and prevent future occurrences, according to the Mayo Clinic.
