Corns on the skin of the foot typically develop as a protective measure against continual friction and pressure and on the skin due to ill-fitting shoes, walking barefoot and athletic sports, explains Healthline. Individuals with foot conditions such as bunions or hammertoes are also at risk of developing corns.
Corns that develop on the outer edge of the pinkie toes are typically caused by small bone spurs in the toe, explains Constantouris Foot Care. When corns develop between the fourth and fifth toes, they are referred to as soft corns and must be treated to prevent skin ulceration and infection.
Treatment options for corns include removal of the excess skin, custom orthotic shoe inserts and wearing comfortable shoes, explains Mayo Clinic. In certain cases, surgery may be recommended if the corns are due to an underlying foot condition. It is important for sufferers to seek medical treatment if they choose to have the skin surrounding the corns removed, as attempting to treat the problem at home can increase the risk of infection.
Individuals with soft corns between the toes may find relief by placing cotton padding over the affected areas, explains Family Foot Care, PC. Steroid injections may also be recommended to shrink the corns and alleviate pain.
