Are there any roots in corns on the feet?

Corns are a frequent problem on the foot. Corns are a natural response to pressure as the skin thickens up to safeguard itself from that pressure. At some stage the process goes wrong and becomes so thick that it is painful. There is a consistent myth that corns have roots which they carry on growing back from once you attempt to remove them. This is just like the analogy of plants which grow back from their roots if you chop the top of the plants off. This analogy has been given to corns as they carry on growing back, however they do not have roots to grow back from.
Corns are caused by pressure and a proficient podiatrist could easily eliminate a corn. However, after the corn is removed if the pressure that caused it is still there then, of course, it will re-grow. It grows back since the cause continues rather than because the podiatrist left a root there for this to grow back from. That pressure may be from poor fitting footwear or from something like a claw toe or bunion leading to greater pressure on an area. If the corn is underneath the foot, then the cause is increased pressure on the spot where the corn is, probably due to the way you walk.
The myth persists because they do come back, so its necessary to remove the cause when the corn is taken off. There isn’t any root to be extracted. This means that the pressure on the foot where the corn was needs to be lowered or removed. This can involve issues like using better fitting footwear or the use of padding to get pressure off the area where the corn is. Sometimes surgery can be necessary to the bone beneath the corn to get rid of the pressure. If that cause isn’t removed or decreased then the corn will return, so it is clear to understand where the myth about corn roots derives from.
