Do corns on the foot have roots?

Corns are a common problem affecting the foot. Corns are a natural response to pressure as the skin thickens up to safeguard itself from that pressure. At some stage this process goes wrong and becomes so thick that it is painful. There's a continual myth that corns have roots that they can keep growing back from once you attempt to take them out. This is just like the analogy of plants which re-grow from their roots if you chop the top of the plants off. This analogy has been given to corns since they carry on growing back again, however they don't have roots to grow back from.


Corns are caused by pressure and a experienced podiatrist could easily eliminate a corn. The problem is that after the corn is taken off if the pressure which caused it is still there then, of course, it will come back. It develops back because the cause is still there rather than because the podiatrist left a root there for the corn to grow back from. That pressure could be from a poor fitting shoe or from something similar to a claw toe or bunion leading to greater pressure on an area. If the corn is under the foot, then the cause is greater pressure on the area where the corn is, most likely due to the way you walk.

The myth is persistant because they do return, so its crucial that you remove the cause when the corn is removed. There is absolutely no root to be extracted. This means that the pressure on the foot the location where the corn has been should be decreased or removed. This can involve issues like using better fitting footwear or the use of padding to get pressure off the location where the corn is. Sometimes surgery can be required to the bone under the corn to eliminate the pressure. If that cause isn't eliminated or reduced then the corn will come back, so it's easy to see where the myth regarding corn roots arises from.
