What is Deep Vein Thrombosis?
This disease occurs when blood thickens and forms a clot, usually in the deep veins of the leg. It is most commonly treated with blood thinners or anticoagulants. It needs immediate attention, because if a clot forms and a piece of it breaks off and travels to the lungs, breathing can become difficult and large clots can be potentially life threatening. Sudden onset of swelling, pain, redness or warmth along the affected vein may occur, often with a history of prolonged inactivity, (for example long car trips, plane rides, lengthy illness with minimal ambulation, etc.). However, it is possible to not have any symptoms.
