What Are Pressure Ulcers of the Foot?
Force or friction against the bottom of your foot causes the skin to thicken, forming a callus. If the skin keeps thickening, the callus presses up into the foot. This kills healthy tissue and causes pain. Unfortunately, you may not notice the pain if you have neuropathy, a health problem that limits how much feeling you have in your feet. Diabetes is a common cause of neuropathy. As healthy skin dies, an ulcer forms. Ulcers may progress from hot spots to infected wounds very quickly.
