FHN - Corns Corns like calluses develop from an accumulation of dead skin cells on the foot, forming thick, hardened areas. They contain a cone-shaped core whose point can press on a nerve below, causing pain. Corns are a very common ailment that usually form on the tops, sides and tips of the toes.
Corns can become inflamed due to constant friction and pressure from footwear.
Corns that form between the toes are sometimes referred to as soft corns. Some of the common causes of corn development are tight fitting footwear, high heeled footwear, tight fitting stockings and socks, deformed toes, or the foot sliding forward in a shoe that fits too loosely. Soft corns are result from bony prominences and are located between the toes. They become soft due to perspiration in the forefoot area. Complications that can arise from corns include bursitis and the development of an ulcer.
