Corns & Callous

Callus is an extended area of thickened, hard skin on the sole or sides of the foot. It is usually symptomatic of an underlying problem such as a bony deformity, a particular style of walking or inappropriate footwear. Some people have a natural tendency to form callus because of their skin type. Elderly people have less fatty tissue in their skin and this can lead to callus forming on the ball of the foot.

Corns are caused by pressure or friction over bony areas, such as a joint, and they have a central core which may cause pain if it presses on a nerve. There are five different types of corns, the most common of which are ‘hard’ and ‘soft’ corns.  Hard corns are the most common and can be likened to ‘walking on a small stone’.  Soft corns occur between the toes and can have a rubber like texture.  Seed corns are tiny corns that occur on the bottom of the feet and are usually painless.  Neurovascular corns have both nerve fibres and blood vessels and can be very painful.
