Corns are formed due to repeated focal pressure on an area and can become very painful, even if they are tiny, usually due to depth of the ‘core’.
There are three different kinds of corns and they typically occur in different sites on the feet and on different types of skin.
Corn plasters with medicaments are strongly discouraged as they can cause extensive burn to surrounding healthy skin due to the strong acid content and can even lead to infection. It will often have minimal effect on the corn itself.
It is therefore important to consult a podiatrist/chiropodist to fully get them resolved. The treatment is pain-free and involves enucleating the corn fully, pin pointing the underlying cause, which is usually poor footwear or a foot deformity. Corns can be cured by removing the force which is causing it. Deflective padding and digital corn devices are often used to reduce he pressure.
