There are a lot of misunderstandings around the problem of corns on the feet. Corns are a condition related to there being excessive force on an area of skin. Regarding the foot this greater pressure could be as a result of toe deformity like hammer toes or bunions where force from the footwear creates the corn. It might be because of a fallen metatarsal bone, leading to a corn or callus on the bottom of the foot. Most of these corns and calluses are just a natural response of the skin to excessive pressure. All that is going on is that the skin thickens up to offer protection to itself. This is a normal and healthy reaction of the skin. Having said that, as the force that caused that thickening remains, the skin will become so thick that it results in being painful. A skilled podiatrist could easily take out a corn. It is not complicated.
However, after it has been taken off, it will just come back again at some point and unless the reason behind that increased pressure is not taken away. This is when the myths come into place. Some individuals may possibly accuse the podiatrist of not really performing their job appropriately, when they most likely did, however the corn returned as the force, possibly from poorly fitting footwear is still present. Others think corns possess roots and the podiatrist did not take away the root. They believe the corn comes back because the Podiatrist decided not to take away the root (much like the plant example, it grows back again if its roots are not eliminated). Corns do not have roots. That's the myth. They keep returning as the cause of will still be there. The only way to eliminate corns once and for all is to get rid of the cause. That means the hammer toe or hallux valgus need to be fixed, or better fitting shoes used so there is no pressure on it or foot orthoses to get pressure of the fallen metatarsal is needed. If you have a problem with corns, then consult with your podiatrist your options to obtain long lasting help.
