Corns are thickened areas on the skin’s surface, and they can be irritating and painful. Corns are commonly found on the feet, and they are typically circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.
While corns are often confused with calluses, there is a difference between them. Corns are raised bumps that consist of rough, thickened areas of skin that may be dry or waxy. They also tend to be surrounded by skin that is inflamed and are usually much smaller than calluses.
