Corns and Calluses

What Are They?
Corns and Calluses are thick, hardened layers of skin that develop when your skin tries to protect itself against friction and pressure.  Neither is dangerous, but can cause irritation.  They most often develop on the feet and toes or hands and fingers.  Corns develop near a bony area of a toe or between toes.  A callus is usually on the underside of the foot.
You may have a corn or a callus if you notice:
  • A thick, rough area of skin
  • A hardened, raised bump
  • Tenderness or pain under your skin
  • Flaky, dry or waxy skin
Corns and calluses are not the same thing.​
  • Corns are smaller than calluses and have a hard centre surrounded by inflamed skin.  Corns tend to develop on parts of the feet that don't bear weight, such as the tops and sides of your toes and even between your toes.  They can also be found in weight-bearing areas.  Corns can be painful when pressed.
  • Calluses are rarely painful.  They usually develop on the soles of the feet, especially under the heels or balls, on your palms, or on your knees.  Calluses vary in size and shape and are often larger than corns.
When to see a Podiatrist
If a corn or callus becomes very painful or inflamed, see your podiatrist.  If you have diabetes or poor blood flow, call Riverton Podiatry before self-treating a corn or callus because even a minor injury to your foot can lead to an infected open sore (ulcer).
