Corn after treatment

Corn (pathology) is a type of skin lesion that typically develops as a response to pressure or friction. They commonly occur on the feet, particularly on the soles, and can cause significant discomfort and pain.

Causes

Corns are caused by repeated pressure or friction on an area of skin. The most common cause is wearing shoes that do not fit properly. Tight shoes and high heels can compress areas of the foot. When the foot is also subjected to the pressure of walking or running, corns can develop on the bony or prominent areas of the foot. Other possible causes include walking without wearing socks, or wearing socks that do not fit properly.

Symptoms

The symptoms of a corn include a hard, thickened area of skin, pain or tenderness under the skin, and flaky, dry or waxy skin. Corns are usually about the size of a pea and can be either soft or hard. Soft corns are typically found between the toes, while hard corns are often found on the tops of the toes or on the outer side of the little toe.

Treatment

Treatment for corns usually involves avoiding the repetitive actions that caused them to develop. Wearing properly fitting shoes, using protective pads and other self-care measures can help alleviate the symptoms. In severe cases, surgical removal of the corn may be necessary.

Prevention

Prevention of corns primarily involves proper foot care and the use of well-fitted shoes. Shoes should be comfortable, with plenty of room for the toes to move, and socks should always be worn to reduce friction. Regularly moisturizing the feet can also help to prevent the skin from becoming dry and prone to corns.
