There are a number of common myths about the issue of corns on the foot. Corns are a condition linked to there being an excessive amount of force on an area of skin. With the foot this greater force can be due to a toe deformity like hammer toes or hallux valgus where by pressure from the shoe causes the corn. It might be due to a dropped metatarsal bone, leading to a corn or callus on the bottom of the foot. These types of corns and calluses are a natural result 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 natural reaction of the skin. However, because the force that caused that thickening continues, the skin will become so thick that it will become painful. A qualified podiatrist will be able to remove a corn. Its not hard.
However, after it has been taken out, it will just return at some point and unless the cause of that increased pressure isn't taken away. This is when the myths come into place. Some individuals might allege the podiatrist of not necessarily undertaking their job effectively, when they more than likely did, but the corn came back as the pressure, possibly from poorly fitting footwear is still there. Others assume corns have got roots and the podiatrist just didn't get rid of the root. They presume the corn comes back because the Podiatrist decided not to get rid of the root (like the plant example, it will grow back again if its roots are not eradicated). Corns do not have roots. That's the misconception. They keep coming back because the cause of will still be present. The only method to eradicate corns completely would be to eliminate the cause. That means the claw toes or bunion need to be fixed, or better fitting shoes used so there isn't any pressure on it or foot orthoses to get pressure of the fallen metatarsal is needed. If you do have a issue with corns, then consult with your podiatrist the alternatives to obtain permanent help.
