Corns on the foot are painful problems that result from too much pressure on the skin from poor fitting shoes or bony deformities. To eliminate corns, all you need to do is take away that pressure which caused the corn. Its that easy. A corn or a callus is part of a natural process which the skin undergoes to shield itself. When there may be an excessive amount of pressure on an area of skin, the skin thickens up to protect itself. However, if that pressure remains over a long time, then the skin becomes so thick that it can be painful. If that pressure is spread over a broader area of skin, then that is termed as a callus. If that pressure is over a lesser far more focal location, then that is a corn. The sources of that greater pressure could be a number of things such as a claw toe, a bunion or a dropped metatarsal. A good evaluation is often necessary to identify just exactly what it is that is causing that higher pressure and exactly how easy it will be to get rid of that greater pressure.
To get rid of corns totally, you will have to get rid of the cause. A competent podiatrist can easily remove a callus and corn by carefully debriding it with a scalpel. Nevertheless, that corn will come back if the cause is not eliminated. They don't really keep returning for the reason that the podiatrist failed to remove it properly or because the corn has roots (they don’t). They keep returning for the reason that the pressure that caused them remains. That should be removed if the corns is to be stopped from coming back. The way that this pressure is taken away is based on what is causing the greater pressure. It can be as easy as finding a better fitting pair of footwear or it could be as complex as needing some surgery to take care of the toe deformity that may be resulting in the pressure creating the corn.
