Corns and calluses are thick, hardened layers of skin that develop when your skin tries to protect itself against friction and pressure. The area could have single or multiple corns.. Since repeated contact is required, calluses are most often found on feet because of frequent walking. Calluses are generally not harmful, but may sometimes lead to other problems, such as skin ulceration or infection. However, if you have diabetes or another condition that causes poor circulation to your feet, you’re at greater risk of complications from corns and calluses.
Signs & Symptoms:
You may have a corn or 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 often confused, but they’re not the same thing.
- Corns are smaller than calluses and have a hard center surrounded by inflamed skin. Corns tend to develop on parts of your feet that don’t bear weight, such as the tops and sides of your toes, though they can also be found in weight-bearing areas. Corns can even develop between your toes. Corns can be painful when pressed.
- Calluses usually develop on the soles of your feet, especially under the heels or balls, on your palms, or on your knees. Calluses are rarely painful and vary in size and shape, though they’re often larger than corns.
