(HealthDay News) -- Corns and calluses are similar areas of thickened skin that form on the feet, often from friction caused by poorly fitted shoes.

The American Podiatric Medical Association offers these potential treatment methods:

• Leave the corns or calluses alone if they aren't painful or bothering you.
• Look for the causes of these problems and make changes to footwear, if needed.
• See a podiatrist, particularly if you are diabetic, or have poor circulation or a serious illness.
• Pad your shoes, if your podiatrist recommends doing so.
• If you have a very large corn or callus, your podiatrist may recommend using a surgical blade to reduce its size.
