Quick guide
This page provides general health information and does not diagnose an individual condition. Persistent, worsening or concerning symptoms should be assessed by an appropriately qualified health professional.

Understanding the problem

Callus is a broader area of thickened skin, while a corn is usually a smaller, more concentrated area of hard skin with a central core. Both form as a protective response to repeated pressure or friction.

Common contributing factors

What can you do?

Seek assessment
Seek assessment for redness, drainage, ulceration, bleeding or suspected infection. People with diabetes, poor circulation or reduced sensation should obtain professional advice before self-treating corns or calluses.
