Foot ulcers are open sores or wounds that develop on the feet, often due to pressure, friction, or poor circulation. They are commonly associated with conditions like diabetes and peripheral artery disease, which can impair blood flow and sensation in the feet. If left untreated, foot ulcers can lead to infections and more serious complications. These ulcers can vary in size and depth, and they may appear red, swollen, or discolored. Proper care, including regular cleaning and dressing, is essential for healing. In some cases, medical intervention may be necessary to prevent further issues, such as amputation.
