Difference between Corn and Callus

Key Difference: A corn appears due to extreme pressure on the skinny or bony prominence of the foot that usually appear on the top of toes or ball of the foot. A callus is a hard, rough area of a skin that usually appears on the underside of hand, foot, or knee.

Corn and Calluses are the most common problem for the podiatrist to treat. People get confused between both; however, corns are much smaller than calluses.

A corn appears due to extreme pressure on the skinny or bony prominence of the foot. They usually appear on the top of toes or the ball of the foot. If someone wears tight sandals, fitting stilettos or high-heeled shoes, the foot will experience skin pressure, and therefore there will be inadequate blood circulation which causes corns. A corn doesn’t itch or bleed; they are usually thick and hardened dead skin. However, the only pain one can feel from corn is when there is direct pressure while standing or walking. They are non-infectious and should be treated as quickly as possible. A corn, which is in between the 4th and 5th toes, is usually the most painful of all and is called a Heloma Molle. Corns can be removed at home, but if someone is experiencing extreme pain then he should consult a dermatologist.

A callus is a hard, rough area of a skin that usually appears on the underside of hand, foot, or knee. It is caused due to bumpy distribution of weight or it can also be caused due to improperly fitting shoes. They are usually not harmful, but sometimes may lead to other problems like infection. A callus may have a small amount of pain that one will feel as though there is a little stone in the stone that cannot be taken out. They did not require any special and they also can be removed at home. A very large or painful callus may require treatment.
