A Corn is a thickening, or bump, on the outer skin layer. It usually develops over bony areas, such as the toe joints. Corns may also develop between the toes. A callus is a painless thickening of skin due to repeated pressure or irritation. Calluses can appear on any part of the body, especially the hands, feet and knees.
Causes of Corn Or Callus
Corns and calluses are the result of the skin forming a protective area in response to repeated irritation. Continued pressure causes the irritated area to grow at a faster rate, leading to overgrowth.
Signs and Symptoms of Corn Or Callus
Corn's form a small, tender and painful raised bump on the side or over the joint of a toe. They are usually 3 mm to 10 mm in diameter and have a hard center. A callus typically produces a rough, thickened area of skin. These occur in areas that have been subjected to repeated pressure or irritation.
