Overview

Corns are small, thickened areas of skin that typically develop on the feet, especially on the tops and sides of toes. They are formed in response to pressure or friction, often from wearing tight or ill-fitting shoes. Corns can be painful, especially when pressed, and are usually more defined and smaller than calluses. They often have a hard center surrounded by inflamed skin.

Causes

• Ill-Fitting Shoes: Shoes that are too tight or too loose can cause friction and pressure, leading to corn formation.
• Toe Deformities: Conditions like hammertoe or bunions can increase pressure on certain areas of the foot, resulting in corns.
• High Heels: Wearing high heels can put excessive pressure on the toes, leading to the development of corns.
• Lack of Socks: Not wearing socks or wearing poorly fitting socks can cause friction between the shoe and the skin, promoting corn formation.
• Repeated Movements: Activities that involve repeated rubbing or pressure on the feet, such as running or standing for long periods, can lead to corns.

Treatment

Treatment for corns typically involves reducing the pressure and friction that caused the corn in the first place. This can be done by wearing properly fitting shoes and using protective pads or cushions to relieve pressure on the affected area. Soaking the feet in warm water can soften the corn, making it easier to remove with a pumice stone. Over-the-counter corn pads containing salicylic acid can also help dissolve the thickened skin. In persistent or painful cases, a healthcare professional might trim the corn or prescribe stronger treatments.
