A peripheral artery disease doctor specializes in diagnosing and treating reduced blood flow in the arteries, especially in the legs and feet. Peripheral artery disease (PAD) can cause symptoms such as leg pain while walking, slow-healing wounds, and fatigue. Early diagnosis is important to prevent complications and improve circulation. A skilled peripheral artery disease doctor may recommend lifestyle changes, minimally invasive procedures, or advanced vascular treatments based on the severity of the condition.
