A "corn" is a small circular thickened lesion in the skin of the foot. It usually forms due to repeated pressure on the skin, such as the rubbing of a shoe. The name "corn" comes from its resemblance to a kernel of corn. A corn is different from a callus in that it has a central core of hard material.
People with foot deformities, such as hammertoes, often suffer from corns because the tops of the bent toes rub against the tops of shoes.
There are a number of treatment options for corns. When corns get hard enough to cause pain, a foot and ankle surgeon will recommend the treatment option most appropriate for you. However, if the underlying cause of the corn is not treated or removed, the corn may return. It is important to avoid trying to remove a corn at home or using medicated corn pads, as serious infection may occur.

Skin & Nail Issues
Athlete's foot and fungal nails are the most common fungal problems with feet.
Many people don't realize they have a fungal nail problem and, therefore, don't seek treatment. Yet, fungal toenail infections are a common foot health problem and can persist for years without ever causing pain. The disease, characterized by a change in a toenail's color, is often considered nothing more than a mere blemish. Left untreated, however, it can present serious problems.

Ingrown toenails occur when the corners or sides of the toenail dig into the skin, often causing infection. Also known as onychocryptosis, ingrown toenails, start out hard,swollen, and tender. Left untreated, they may become sore, red, and infected and the skin may start to grow over the ingrown toenail. They are usually caused by trimming toenails too short, particularly on the sides of the big toes, and may also be caused by shoe pressure (from shoes that are too tight or short), injury, fungus infection, heredity, or poor foot structure. A common ailment, ingrown toenails can be painful. Click here for more information on ingrown toenails.
