Corns and Calluses

Corns and calluses are areas of thick, hard skin, formed due to the skin’s resistance to friction and pressure. They are not contagious but can be unsightly. They usually disappear over time once the source of friction and pressure has been eliminated. They develop on the feet or hands.

Corns and calluses develop due to repetitive actions such as using tools or instruments regularly, wearing ill-fitting shoes or not wearing socks. People with bunions, hammer, claw, or mallet toes have a higher chance of developing corns and calluses. Corns and calluses are not exactly the same thing.

• Corns are smaller than calluses and have a hard core surrounded by inflamed skin. They usually develop on the top, side or between the toes. They can be painful

• Calluses usually develop on your hands and feet and are rarely painful. They range in sizes, but are larger than corns. They usually develop under the heels.

When to seek expert advise

You only need to go to a doctor if the corns or calluses become painful or inflamed. If you suffer from diabetes or any other systemic illness, avoid self-treatment at home. Set an immediate appointment with a doctor working with the Teeth and Skin at The Aga Khan University Hospital.​
