Corns & Calluses

Updated: Jan 6, 2019

Keeping your feet in tip top condition is essential, especially as you get older. Not only is it harder to care for your feet yourself when it is hard to bend down, but as you age your feet have suffered more cumulative wear & tear.


A corn is a spot on the foot made of skin that has thickened as a response to pressure. Though the skin buildup is the body's way of protecting itself, when it goes on too long, the resulting corn can be painful. When the problem is serious enough to warrant medical attention, a podiatrist is the right professional to see about getting the corn removed. Corns are, in fact, one of the most common problems that such specialists treat.

Corns are formed due to a small area of very high pressure, often with a callus over the top of them. Corns can also be due to friction (for example, excessive sliding of the foot in shoes especially if the person has very dry skin). Corns can be very painful if they are deep enough to press on nerves in the skin.

Corns are often small, but have a ‘core’ of concentrated hard skin in the centre of them; it is this core that often causes the pain. The core needs to be removed by a podiatrist to provide relief.

There are several different types of corns:

Hard corn (Heloma durum) – These are usually on the sole of the foot, over bony areas and occasionally the tops of the toe joints. These present as a small, concentrated area of hard skin.

Soft corn (Heloma molle) – These are corns that are found between the toes. They are named because they are often moist and as a result are softer than corns found elsewhere on the feet.

Seed corn (Heloma millare) – These are small, relatively superficial corns that usually result from friction and dry skin. May appear anywhere on the sole of the foot.

Vascular/neurovascular corn – These corns have some degree of blood vessel and/or nerve involvement, and can bleed or be painful when reduced. These usually develop in areas that have been subjected to very high pressures over a period of time.


This refers to layers of excess hard skin, which often develops on the bottom of the feet, around the back of heels, the sides of the big toe joints and the top of lesser toe joints.

The reason callus develops is because of excess or unusual pressure in the affected area whilst a person is walking and/or standing. The increased pressure results in the body thickening the skin in this area. This happens on purpose as a protective layer between the ground or shoes and the skin, or over bony prominences. Corns & calluses can be treated by our podiatrist, Lorraine Humphrey with a 30 minute appointment. Call 01323 301480 to book your appointment now.
