Corn (Clavus)

Overview

A corn is a thickened callus that forms on the skin of the hands or feet due to prolonged pressure and friction, causing localized cone-shaped thickening of the epidermis. It usually occurs on the feet and causes pain when compressed while walking. Wearing loose, well-fitting shoes helps prevent it.

Symptoms

• Localized thickened keratin
• Central hard core
• Pain on pressure
• On pressure-bearing soles
• Worsens with walking

Treatment

Caused by prolonged friction and pressure. Wear loose shoes, apply corn plasters to soften and remove it, and consider surgical excision for stubborn cases.

Dietary advice

A normal balanced diet is sufficient; choose suitable footwear to reduce friction.
