Corns and calluses are regions of thickened skin which develop to shield that area from pressure and irritation. They will occur when something such as a shoe puts pressure against the foot repeatedly or brings about excessive pressure against part of the foot. It is called a callus typically if the thickening of skin happens on the bottom of the foot. If thickening takes place on the top of the feet or toe it is usually referred to as a corn. However, there is a great deal of overlap between a corn and a callus. They aren't contagious but could turn out to be painful when they become too thick. In individuals with diabetes this can lead to more severe foot conditions, so that they should be given serious attention.

Corns often happen when a toe rubs against the inside of a shoe or there is a toe deformity. High pressure on the balls of the feet, that is frequent in women who often wear high heels may cause calluses to develop underneath the balls of the feet. People that have certain deformities of the foot, for example hammer toes, claw toes, or bunions are susceptible to corns and calluses. Corns and calluses usually have a rough dull looking physical appearance. They can be raised or circular and without correct evaluation, they could be hard to differentiate from warts. Should you have a corn or callus that is creating pain and discomfort or interfering with your day to day activities then it is most likely best if you visit a podiatrist. This can be even more vital if you have diabetes or poor blood circulation. The podiatrist will perform a thorough evaluation of the feet along with your shoes and look at the way you walk to figure out exactly why you could have the corns and callus. For mild corns or calluses they could suggest varying your shoes and make use of padding in your shoes. If they are larger, then your podiatrist could minimize them with a surgical blade to cautiously and skilfully shave away the thickened skin. Further treatments are usually necessary if the corn or callus.
