Toe Pain

Toe Pain

A corn is a type of callus, a protective layer of dead skin cells that form due to repeated friction. It is cone-shaped and has a knobby core that points inward. This core can put pressure on a nerve and cause sharp pain. Corns can develop on the top or between toes. If a corn develops between the toes, it is may be called a soft corn if it is kept pliable by the moisture from perspiration.

Corns develop as a result of friction from the toes rubbing together or against the shoe. They often occur from the following:

• Shoes, socks, or stockings that fit too tightly around the toes
• Pressure on the toes from high-heeled shoes
• Shoes that are too loose can also cause corns due to the friction of the foot sliding within the shoe
• Deformed and crooked toes

Preventing Corns and Calluses and Relieving Discomfort. To prevent corns and calluses and relieve discomfort if they develop:

• Do not wear shoes that are too tight or too loose. Wear well-padded shoes with open toes or a deep toe box (the part of the shoe that surrounds the toes). If necessary, have a cobbler stretch the shoes in the area where the corn or callus is located.
• Wear thick socks to absorb pressure, but do not wear tight socks or stockings.
• Apply petroleum jelly or lanolin hand cream to corns or calluses to soften them.
• Use doughnut-shaped pads that fit over a corn and decrease pressure and friction. They are available at most drug stores.
• Place cotton, lamb's wool, or mole skin between the toes to cushion any corns in these areas.

Removing Corns and Calluses. To remove a corn or callus, soak it in very warm water for 5 minutes or more to soften the hardened tissue, then gently sand it with a pumice stone. Several such treatments may be necessary. Do not trim corns or calluses with a razor blade or other sharp tool. If the cutting instrument is not sterile, infection can result, and it is easy to slip and cut too deep, causing excessive bleeding or injury to the toe or foot.

Medicated Solutions and Pads. There are numerous over-the-counter pads, plasters, and medications for removing corns and calluses. These treatments commonly contain salicylic acid, which may cause irritations, burns, or infections that are more serious than the corn or callus. Use caution with these medications. The following people should not use them:
