Corns

Corns are thickened areas of skin that can become painful and are commonly found on the feet due to pressure. They are generally caused by friction or pressure from skin rubbing against bony areas or against an irregularity in a shoe.

Causes

Corns are caused by pressure or friction on skin. A corn is a type of callus, a part of the skin's normal defense against pressure or rubbing. This might happen when the skin rubs against a bone, a shoe, or the ground. Most corns occur on the tops, sides, and tips of toes.

Symptoms

Corns often occur on the feet, especially on the tops and sides of the toes, soles of your feet and even between toes. They can also affect other areas of the body. The symptoms of a corn can vary depending on the type and location. They may include:

• Hard, rough area of skin
• Raised, hardened bump
• Tenderness or pain under the skin
• Flaky, dry or waxy skin

Treatment

Treatment for corns will vary depending on the severity and location. Some common treatments include:

• Using over-the-counter pads
• Using a pumice stone or callus file to reduce the size of the corn
• Wearing shoes that fit properly and provide enough room for your feet
• Using protective coverings or bandages over the corn to help reduce friction
• Applying salicylic acid to the corn
• In severe cases, surgery may be required

Prevention

Prevention of corns primarily involves the avoidance of the repetitive actions that caused them to develop. Wearing shoes that fit properly and using protective pads can help to prevent the development of corns.
