Corns
Foot and toe corns are the irritating small bumps that seem impossible to remove. Usually appearing on the sides or tops of your toes, corns are commonly a result of shoe friction.
Similar to calluses, toe corns 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 can become inflamed due to constant friction and pressure from footwear. Corns that form between the toes are sometimes referred to as soft corns.
