Corns and calluses are thickened areas of skin caused by pressure or friction on the skin. Corns usually appear on the tops and sides of toes. Calluses can appear in any place that experiences friction, such as the bottom of your feet or the palms of your hands.
CORNS: Corns generally occur at pressure points, typically on the bottom of the feet and the side of the toes. They can be painful.
A hard corn is a small patch of thickened, dead skin with a central core. A soft corn has a much thinner surface and usually occurs between the 4th and 5th toes. A seed corn is a tiny, discrete callus that can be very tender if it’s on a weight-bearing part of the foot. Seed corns tend to occur on the bottom of the feet.
CALLUSES: Calluses are painless thickenings of the outermost layer of the skin. They can develop on hands, feet, or anywhere there is repeated friction.
What Causes Corns and Calluses?
Some corns and calluses on the feet develop from improper walking motion, but most are caused by ill-fitting shoes. Other risk factors for developing a corn or callus include foot deformities and wearing shoes or sandals without socks, which leads to friction on the feet. Rubbing or pressure can cause either soft corns or plantar calluses.
Call Your Doctor or Chiropodist About a Corn or Callus If:
- You cut a corn or callus and cause it to bleed. The break in the skin can cause infection.
- A corn discharges pus or clear fluid, which means it is infected or ulcerated. Both conditions need urgent medical attention.
- You develop a corn and also have diabetes, heart disease, or other circulatory problems
