Corns and calluses are regions of thickened skin that occur to guard that area from pressure and irritation. They could occur when something for example footwear rubs on the foot continuously or causes excessive pressure against part of the foot. It is called a callus commonly if the thickening of skin happens on the bottom of the foot. If thickening occurs on the top of the foot or toe it is usually called a corn. However, there is a great deal of overlap between a corn and a callus. They are not transmittable but tend to grow to be painful when they become too thick. In people with diabetes this might lead to more serious foot problems, so that they have to be taken seriously.

Corns generally occur when a toe rubs on inside of the footwear or there is a toe deformity. High force on the balls of the foot, that is common in women who frequently wear high heel shoes could cause calluses to develop under the balls of the foot. Those with particular deformities of the foot, for example hammer toes, claw toes, or bunions are prone to corns and calluses. Corns and calluses usually have a rough dull looking physical appearance. They can be raised or rounded and without correct analysis, they can be hard to differentiate from verruca. If you have a corn or callus which is causing discomfort and pain or interfering with your day to day activities then its most likely best if you visit a podiatrist. This is certainly even more crucial if you have diabetes or poor blood circulation. The podiatrist should conduct a complete check-up of the feet as well as your footwear and assess the way you walk to determine why you have the corns and callus. For minor corns or calluses they might propose varying your footwear and use padding in your shoes. If they are more substantial, then your podiatrist might reduce them with a scalpel to carefully and skilfully shave away the thickened skin. Further treatments may be needed if the corn or callus recurs.
