Corns can be a common condition of the foot which can be painful and difficult to manage. Corns are caused by too much pressure on an area of skin. They are part of a natural mechanism that has gone wrong. When there is excessive pressure on the skin, that region of skin will thicken up to protect itself. If the pressure continues over a extended period of time, it becomes so thick that it is painful. This is the same as the mechanism that occurs when, by way of example, chopping wood. Doing this, you eventually produce a callus on your hand. The same thing happens on the foot with pressure from the ground or pressure on a toe from the shoe. When you halt cutting wood, the thicker skin on the hands subside. The challenge in the foot is that you keep wearing footwear and you continue walking, so the pressure continues and the thicker skin forms into a corn and becomes painful.
Getting rid of corns is fairly easy and a skilful podiatrist will be able to take them off. That's the easy bit. The hard part is stopping them returning. It is one thing to take them off, but if you don't take away that cause (the higher pressures on the region), then they will just keep coming back eventually. Corns do not possess roots which they grow back from. They keep coming back because the cause remains. Taking away a corn is similar to managing the symptom. They will return unless the cause is taken away. This is where the ability of a podiatrist is necessary to identify the proper cause. A complete assessment is required of the function, shoes, foot structure and lifestyle to work out just what it is that is causing the higher pressure. Once that cause has been determined, then different treatments can be used to get rid of that pressure. This can range from simple footwear suggestions to foot orthotic to surgical procedures.
