What is it?

Corns and calluses are areas of thick, hard skin. They mostly form on the feet and toes. They can also form on hands and fingers. While they can cause similar symptoms, corns and calluses are not the same:

  • Corns – smaller than calluses, painful and inflamed, and caused by specific areas of pressure 
  • Calluses – rarely painful and usually affect a large area of skin on the soles or balls of the feet, knees or palms 

Corns and calluses rarely cause problems. People with diabetes and poor blood flow need to be careful that treatment doesn’t lead to infection. Most healthy people only need treatment if they feel uncomfortable or are worried about the appearance.
