Corns and calluses

Also called Corns, Calluses, or Hard skin

Corns and calluses are areas of hard, thick skin that form where there is repeated pressure or friction, usually on the feet. Calluses are larger patches, often on the soles; corns are smaller, deeper and can be painful. They are the skin's way of protecting itself.

What it is

Well-fitting shoes, soft insoles, padding and regularly softening and filing the skin help.

People with diabetes or poor circulation should not treat corns themselves and should see a podiatrist, as small foot wounds can become serious.

Common signs

  • A hard, raised bump of skin (corn)
  • A larger area of thick, rough skin (callus)
  • Pain when pressing or walking
  • Flaky or dry skin

How it is usually diagnosed

  • Recognised by a GP, pharmacist or podiatrist

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Podiatry notes
  • Foot check results if you have diabetes

Questions to ask your doctor

  • What is causing the pressure?
  • Would insoles or different shoes help?
  • Is it safe for me to treat them myself?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Signs of infection, such as redness, warmth, pus or fever, especially if you have diabetes
