Corns and calluses are thick, hardened layers of skin that develop when your skin tries to protect itself against friction and pressure. They most often affect the feet and toes or the hands and fingers. Corns and calluses can be unsightly.
If you are healthy, you won't need treatment for corns and calluses unless they cause discomfort. For most people, once the source of friction or pressure is removed, the corns and calluses will disappear.
If you have diabetes or another condition that causes poor blood flow to your feet, you are at increased risk of developing complications from corns and calluses. Consult your doctor about how to care for and remove corns and calluses if you have this condition.
Pressure and friction from repetitive actions can cause calluses and corns. Some sources of this pressure and friction include:
Wearing ill-fitting shoes. Tight, high-heeled shoes can put pressure on areas of the feet. When shoes are too loose, the foot may slip repeatedly and rub against the shoe. The foot may also rub against a crease or seam inside the shoe.
Not wearing socks. Wearing shoes or sandals without socks can cause friction against the foot. Ill-fitting socks can also cause problems.
Playing toys or using hand tools. Calluses on the hands may result from repetitive pressure from playing toys, using hand tools, or even writing.
1. A corn is smaller than a callus and has a hard center surrounded by inflamed skin. Corns tend to grow on parts of your feet that don't bear weight, such as the tops and sides of your toes and between the toes. They can also appear in weight-bearing areas. Corns become painful when pressure is applied to them.
2. Calluses are rarely painful. They usually grow on the soles of your feet, especially under the heels or the ball of your foot, or on the palms of your hands or knees. Calluses vary in size and shape and are often larger than corns.
Treatments for corns and calluses typically involve avoiding the repetitive actions that cause them. Wearing properly fitting shoes, using bandages, and performing other self-care measures can help reduce their appearance.
If corns or calluses persist or become painful despite self-care efforts, medical treatments can provide relief:
1. Trimming excess skin. A doctor can scrape away excess or thickened skin or trim a large corn with a scalpel, usually during an office visit. Patients should not attempt this themselves, as it can lead to infection.
2. Corn removal medications. A doctor can also apply a patch containing 40 percent salicylic acid (such as Clear Away, MediPlast, or others). These patches are available without a prescription. The doctor will tell the patient how often to replace the patch. They may also recommend using a pumice stone, nail file, or emery board to remove dead skin before applying a new patch. A prescription may also be obtained that includes salicylic acid in gel form for application to larger areas.
3. Shoe inserts. In cases of underlying foot deformity, a doctor may prescribe specially designed shoe inserts with pads (orthopedics) to prevent recurrence of the injury.
4. Surgery. In rare cases, a doctor may recommend surgery to correct the bone alignment causing the friction.
