As your heart beats, it pumps blood through a network of blood vessels called the circulatory system. The vessels are flexible tubes that carry blood to every part of your body. Arteries carry blood away from your heart, while veins return it.
Vascular diseases include any condition that affects your circulatory system. This includes diseases of your arteries and veins. Vascular pain happens when the communication between blood vessels and nerves is interrupted or damaged because of vascular disease or injuries.
