A callus and a corn are both types of thickened skin that develop as a result of friction or pressure. However, there are some differences between them:

Callus:

A callus is an area of thickened skin that usually develops on the soles of the feet or the palms of the hands. It forms as a protective response to repetitive friction or pressure on the skin. Calluses are typically larger and broader than corns and have a more diffuse, flattened appearance. They are usually painless but can cause discomfort due to their thickness. Calluses often develop on weight-bearing areas of the feet, such as the heels or balls of the feet, and are commonly associated with activities like walking or running.

Corn:

A corn is a smaller, more localised thickening of the skin. It typically forms on the toes, especially on the tops or sides of the toes, or between the toes. Corns are more defined and have a cone-shaped appearance with a central core, which is called the nucleus. The nucleus of a corn can exert pressure on underlying nerves, causing pain or discomfort. Corns often develop as a result of repetitive friction or pressure from ill-fitting shoes, deformities like hammer toes, or abnormal gait patterns.

In summary, the main differences between a callus and a corn are:

• Size and shape: Calluses are larger, broader, and more diffuse, while corns are smaller, more localised, and have a cone-shaped appearance with a nucleus.
• Location: Calluses typically form on weight-bearing areas of the feet, while corns often develop on the toes or between the toes.
• Pain: Calluses are usually painless but can cause discomfort due to their thickness, while corns can be painful, especially when pressure is applied to the nucleus.

If you are experiencing foot discomfort or have concerns about calluses, corns, or any foot-related issues, it is recommended to consult a healthcare professional or a podiatrist for an accurate diagnosis and appropriate treatment.
