Corns & Calluses
Causes of corns & calluses
Corns and calluses are caused by pressure or friction on skin.
A corn is thickened skin on the top or side of a toe, usually from shoes that do not fit properly.
A callus is thickened skin on your hands or the soles of your feet.
The thickening of the skin is a protective reaction. For example, farmers and rowers get callused hands that prevent them from getting painful blisters. People with bunions often develop a callus over the bunion because it rubs against the shoe.
Neither corns nor calluses are serious conditions.
Symptoms of corns & calluses
- Skin is thick and hardened.
- Skin may be flaky and dry.
- Hardened, thick skin areas are found on hands, feet, or other areas that may be rubbed or pressed.
Treatment of corns & calluses
Usually, preventing friction is the only treatment needed. If a corn is the result of a poor-fitting shoe, changing to shoes that fit properly will usually eliminate the corn within a couple of weeks. Until then, protect the skin with donut-shaped corn pads and use a pumice stone or foot foot file to gently wear down the corn.
Calluses on the hands can be treated by wearing gloves during activities that cause friction, such as gardening and weight lifting.
If an infection or ulcer occurs in an area of a callus or corn, unhealthy tissue may need to be removed by a health care provider and treatment with antibiotics may be necessary.
Calluses often reflect undue pressure placed on the skin because of an underlying problem such as bunions. Proper treatment of any underlying condition should prevent the calluses from returning.
Complications of corns and calluses are rare, however if you have diabetes you should ask your doctor to check them for you.
