What does having corns mean?

Painful bumbs: Corns are painful bumps on the feet, usually at pressure points, or in between toes ("soft corns"). They are often caused by tight shoes or excessive walking or running.

Tight shoes: It might be as simple as wearing too tight of a sheo causing the toes to rub together or it could be that you have a bone spur or toe deformity causing the problem. If it is not a tight shoe then you need to be examined.
