Corns on the foot are due to an excessive amount of pressure on that location the location where the corn is. To remove corns, all you need to do is remove that pressure which caused the corn. Its that easy. A corn or a callus is part of a natural process that your skin undergoes to shield itself. Whenever there's an excessive amount of pressure on an area of skin, the skin thickens up to protect itself. However, in the event that pressure remains over a long time, then the skin becomes so thick that it is painful. In the event that pressure is spread over a wider area of skin, then that is called a callus. If that pressure is over a reduced more focal location, then that's a corn. The sources of that increased pressure can be a number of things like a hammer toe, hallux valgus or a dropped metatarsal. A proper assessment is usually required to establish just exactly what it is that is causing that higher pressure and just how easy it will be to eliminate that higher pressure.
To get rid of corns totally, you have to remove the cause. A competent podiatrist can certainly get rid of a callus and corn by thoroughly debriding it using a scalpel. Nevertheless, that corn will return should the reason for them isn't removed. They do not keep coming back for the reason that the podiatrist didn't remove it adequately or for the reason that corn has roots (they don’t). They keep returning for the reason that the pressure which caused them remains. That ought to be eliminated if the corns is to be stopped from recurring. The way that this pressure is removed is determined by why you have the greater pressure. Perhaps it is as easy as getting a better fitting pair of shoes or it can be as complicated as needing some surgery to fix the toe deformity that is resulting in the pressure resulting in the corn.
