What is the difference between thick hard skin and a callus?
The medical term for thick hard skin is callus, so there is no difference between the two. However, while your doctor or podiatrist, may not think there is any difference between thick hard skin and callus, the words might conjure up quite different images in your mind.
When you talk about “thick, hard skin” you are more likely to be referring to skin that covers larger areas across the ball of foot or heel or specific areas on the toes. When you talk about “callus” you are more likely to be referring to a defined plaque, often found on the ball of the foot.
