Diagnosis
Key Points
Diagnosis based on skin appearance
In rare cases, testing may be required to rule out other conditions

Calluses are generally diagnosed based on appearance. In rare cases, testing may be required to rule out other conditions.

Treatment
Goal of treatment is to control and lessen symptoms
Prevention of friction is the primary treatment
*Does not generally require attention by health care professionals
OTC Options: Moisturizers, emery boards, pumice stones, shoe inserts

The primary method of treating Calluses is to alleviate friction on the area. Changing footwear, use of shoe inserts, and moisturizing dry skin in the area can help to alleviate this. Emery boards and pumice stones can also be used to pare down the callus.

Treatment by health care professionals is generally not needed, but should be sought out if a callus becomes too bothersome. Paring the affected area or prescribing topical ointments such as Urea to dissolve the thickened skin are among the things that may be recommended. Diabetics should watch Calluses carefully, as there is danger of the formation of diabetic ulcers in these cases.
