Corns are point-like thickenings in the skin. They are often dry, waxy and may have a hard core. It is somewhat more common among women than men. Corn is not contagious, but can occasionally cause inflammation and infections in the skin.
The skin changes occur where the skin is exposed to pressure and friction over time. The skin thickening is intended as a protection to avoid wound damage and blistering of the skin. In the long run, however, the thickened skin forms a painful thorn. Corns often occur due to incorrect/poor footwear, incorrect foot positions and/or physical activity.
The treatment aims to reduce the formation of new, thickened skin (adapted footwear, use of toe separators, corn plasters, etc.), as well as to remove the corn over time. A corn can be removed by using a softening foot bath followed by a foot file/scraper. Sometimes it is necessary to supplement with creams that contain solvents, for example carbamide (10-50%), propylene glycol or salicyl vaseline. Such creams can be bought without a prescription at the pharmacy. Sometimes treatments by a podiatrist may be necessary. If the patient has incorrect postures and/or bone deposits in the foot, orthopedic surgery may be appropriate.
