Peripheral Arterial Disease (PAD), is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs. When you develop PAD, your extremities don't receive enough blood flow to keep up with muscular demand. This causes symptoms of pain and cramping. When you have to stop and take a rest during walking, it is called intermittent claudication. Often times, your podiatrist is the first to detect PAD as your circulation is checked in your feet during routine exams.
