A growth on foot which is hard, thick, causing pain and soreness in the region surrounding it are symptoms of Corns and Callus. Corn – a small circular thickened lesion in the skin of the foot 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.
