Corns
Corns are a thickening of the outermost coating of skin. Medically this thickening is called as hyperkeratosis. Corns develop as skin's usual defence against long-lasting rubbing, pressure and other types of common irritation. So a corn is a defensive thickening of the skin. In the centre of a corn a very thick knot of skin known as core, which is situated over the part of maximum friction or pressure. Mainly corns grow when the foot has been compressed into a shoe that has a contracted toe part. In some cases corns grow on distorted toes that cannot fit easily into regular shoes. A corn occurs mainly at the sole of the foot, on the top of the toes and in between toes. Sometime corns can be extremely painful, particularly if there is reddishness, inflammation and swelling in the region of corn. The Corns may come out as yellow, white, gray, and brown colours, depend on skin type.
There are two main types of corn.
Soft corns
Soft corns are very painful. Normally they develop between toes. Basically they are hard but become softened by constant exposure to moisture because of sweating. Bacteria or fungi sometimes infect soft corns.Hard corns
Most common type of corns is hard corn. They developed in concentrated parts of skin, hard in nature and have about the size of a pea. Sometime they may arise within a broader part of hardened skin. Frequently they occur on toes, and most commonly the fifth toe.There are other rare types of corn.
- Seed corns These are bunch of little corns on the base of foot. Normally they are painless.
- Vascular corns These type of corn develop on blood vessels and bleed if cut.
- Fibrous corns These are corns that have been there for a long period and have become close to deeper layers of the skin.
