Corns and calluses are a build-up of hardened skin and each is located at various parts of the feet. They will normally occur in areas where there is increased pressure. Sometimes warts might be mistaken for corns.

The pain varies from slight tenderness to constant throbbing when pressure is applied. Corns and calluses are not normally harmful but for a diabetic, the result can lead to an infection if left untreated.

Using over-the-counter remedies such as medicated corn plasters are only a short-term fix. If you find a corn or callus, do not attempt to remove them yourself. A podiatrist will not only remove the problem but also provide advice to help prevent this issue from recurring in the future.
