Peripheral Artery Disease (PAD) is a common condition that typically affects the legs. The disease occurs when narrowed arteries reduce blood flow to the legs and feet. When your legs do not have proper blood flow they ache when you walk, and gradually can lead to pain at rest or ulcerations if left untreated.
1. According to the Center for Disease Control (CDC), Peripheral arterial disease (PAD) is a chronic disease in the legs or lower extremities resulting in the narrowing or blockage of the vessels that carry blood from the heart to the legs. The blockage or narrowing is caused by the buildup of fatty plaque in the arteries, called atherosclerosis. PAD can happen in any blood vessel but is usually found in the legs rather than the arms.
