Calluses and Corns

Exams and Tests

Calluses and corns generally are diagnosed during a physical exam. If the calluses or corns are on your feet, you will be asked to take off your shoes and socks so your feet can be examined. If you have calluses on another part of your body, such as your knee or elbow, your doctor will look at those areas as well.

Your doctor may also ask you questions about your work, hobbies, or shoes. If your doctor suspects a problem with the bones of the foot, he or she might do an X-ray of your foot.

If a callus or corn is not located over a bony part of the foot or a pressure point is not obvious, your doctor may look for another cause, such as skin cancer, or may try to find a genetic cause.

If you have diabetes, peripheral arterial disease, peripheral neuropathy, or other conditions that cause circulatory problems or numbness, tell your doctor. These diseases affect your treatment options.
