Three dots on my foot appearing like corn?

Diagnose it first: A healthy, non-diabetic person can sand down his corns or calluses, which are thickened areas of skin cells. Self-care products are over-the-counter at the drugstore's foot-care section. The easiest way to get rid of them is to have a primary care doctor or a dermatologist shave them down with a blade. However, if there are 3 dots in it, it is more likely a wart. Doctor can examine and treat.
