Calluses and corns are thick and hardened layers of skin that develops as a result of increased pressure and friction. It is important to keep in mind that calluses and corns are not caused by any bacterial or viral infections. The causes of calluses and corns are often a combination of foot deformity, foot biomechanical issues, and ill-fitting shoes.
Calluses vs. Corns
Calluses usually develop of the sole of the foot on weight-bearing surfaces (see picture). They vary in size and shape, but often are larger than corns.
Corns are smaller and circular lesions with a hard centre. Corns are usually painful when pressed. They can be found on the sides of the foot and in between the toes. It is important to differentiate between a corn and a wart before starting treatment as they often appear similar.
Treatment
After your foot examination, your chiropodist (foot specialist) will be able to determine the best way to address your calluses and/or corns. Treatment may include:
- Manual removal of calluses/corns
- Padding and offloading devices
- Topicals including foot creams
- Custom foot orthotics
- Shoe adjustment/modifications
- Patient home care advice
High Risk Patients
It’s important for people with diabetes, peripheral neuropathy, or peripheral vascular disease to seek chiropody/foot care for calluses and corns immediately. In high-risk patient populations, sometimes a callus/corn can become a potential foot ulcer1. Diabetes Canada recommend people with diabetes to avoid self-treatment at home and avoid using any over-the-counter corn/callus medicated pads2.
