What is Deep Vein Thrombosis?
Deep vein thrombosis (DVT) is a condition in which blood clots form in the deep veins of the body, usually in the lower legs.
While the clotting can be uncomfortable, due to swelling and other symptoms, this condition only becomes dangerous if that blood clot breaks free, travels through the circulatory system and lodges in the lungs, causing a pulmonary embolism, which can kill.
