Corns & Calluses

Calluses and corns are produced by the body to protect the skin and underlying tissues when exposed to continuous pressure or rubbing. Calluses form on the bottom of the feet but can also form on other areas of the body. Corns are thicker and deeper than a callus and have a core. Corns are typically on the top of the foot or toes but can develop on the bottom of the feet also.

Patients who do not have advanced peripheral neuropathy will sometimes describe a corn on the bottom of the foot as feeling like walking on a pebble. it becomes a serious condition when no pain is felt at all. If left untreated, the calluses and corns can cause ulcers and lead to infection.

Patients with hammertoes or other deformities of the feet are prone to developing calluses and corns.

Mild calluses and corns may be treated successfully at home, although it could be important to determine the cause to prevent worsening. Shoes may need to be replaced with more supportive footwear, or inserts may be needed to relieve pressure on the bottom of the feet. Mild filing or cushions may be useful to keep the calluses from advancing.

If the patient has diabetes or poor circulation, calluses and corns should be assessed by a podiatrist. Over-the-counter treatments can be harmful to diabetic patients.

Calluses can be carefully shaved off without pain, as the skin is already dead in that area. Cortisone injections can relieve pain if needed. Surgery would only be necessary if conservative treatment does not help.
