The peripheral vascular system includes the network of arteries and blood vessels that carry oxygen-rich blood to the legs and feet. When these arteries become narrowed or blocked, blood flow can be reduced, leading to symptoms such as leg pain, cramping while walking, numbness, weakness, or slow-healing wounds. Poor circulation in the legs can affect mobility and, if left untreated, may increase the risk of serious complications. Early diagnosis and appropriate treatment can help improve blood flow, relieve symptoms, and protect the health of the legs and feet.
