Being a foot doctor this really is one question which I get asked quite a bit, both clinically and in interpersonal occasions. Corns do not possess roots. After a podiatrist takes out a corn, they generally do are likely to keep coming back, although not because they have got roots. Corns and calluses come back because the cause of the corn or callus is still there. A corn is an portion of skin, frequently on a toe which becomes thicker and uncomfortable. The explanation for that thickened section of skin is too much pressure. It is quite normal for skin to become thicker to protect itself. Give some thought to what happens when you chop a lot of timber and develop a callus on the hands. That is the natural protective process of the skin thickening up to shield itself. Once you stop chopping timber, the calluses disappear completely because the force which caused them has stopped.
It is the equivalent process for a corn or callus on the feet. The skin thickens up in a reaction to increased force. There are various factors behind that increased pressure. There could be a bunion or hammer toes or a dropped metatarsal or perhaps the footwear is too tight. As a consequence of the increased pressure the skin begins to thicken up like the calluses to the palm after you chop wood. However, unlike chopping wood the stress on the feet from the shoes or foot deformity does not stop and as this increased pressure persists the epidermis will continue to get thicker. The callus is usually a much more diffuse area of thickened skin and a corn is a smaller sized but more discrete and much deeper region of thickened epidermis. Eventually it gets so thick it can be sore. A competent podiatrist can easily debride that painful callus or corn with little difficulties and frequently it will certainly no longer end up being painful. However, when the cause of that increased stress isn't eradicated, then the callus or corn will come back. This is where the fabrication they may have roots come from. They are certainly not like organic plant life which have roots that they grow from. The podiatrist did not neglect to remove the roots. They keep returning because the cause continues.
So that you can once and for all eradicate a corn on the foot, then the cause needs to be eradicated. As soon as the corn has been debrided, after that which can give instantaneous pain relief. A good podiatrist are able to look deeper and determine what was probably causing that corn and what can be accomplished to eradicate that reason. It might be as basic as offering shoe assistance and using different or much better fitting shoes. In addition, it could be as intricate as requiring surgery to, for example, fix a bunion which could have been resulting in the increased stress. Sometimes when there is a callus on the underside of the feet, foot insoles may be used to reduce the pressure in those regions. The biggest thing to understand is that foot corns don't have roots and they have a cause. If you need to stop calluses ever coming back then you need to clear out that cause.
