A foot ulcer is a sore or wound that develops on the foot, often due to pressure, poor circulation, or nerve damage. It is commonly seen in individuals with conditions like diabetes or peripheral artery disease. If left untreated, foot ulcers can become infected and lead to more serious complications, including the need for amputation. Treatment for foot ulcers typically involves cleaning the wound, applying dressings, and addressing the underlying causes. Proper foot care, including regular inspections and maintaining good hygiene, is essential for prevention. In some cases, a healthcare professional may recommend specialized footwear or surgery to promote healing.
