what is the difference between a callus and a corn?
The term âcornâ is often used interchangeably with callus. Essentially, they are both caused by the same thing, but visually a corn is often smaller, rounder and deeper, and a callus is usually broader, covering a larger area. A âbunionâ is the name for the enlarged bony bump located behind the big toe at the joint where it attaches to the foot.
