Corn
Corn is a hard patch of thickened skin that generally occurs at the pressure points of your feet and the sides of your toes. They have a hard centre surrounded by inflamed skin. Foot corns usually happen due to an ill-fitted shoe or increased friction and corns are your skin’s response to protect the affected area.
Calluses
Calluses on other hand are thickening on the outer layer of the skin which is painless. They can develop on your hands, legs, feet or any part where there is repeated friction.
Corns and calluses may develop on the feet due to an improper walking motion, but most are caused by ill-fitting shoes. For most people, simply eliminating the source of friction or pressure makes corns and calluses disappear.
If you are not sure about having foot corns or calluses, below are the symptoms that you can refer to:
A thick rough area of skin
A hardened raised bump
Pain under your skin
Flaky or dry skin
