Chronic Venous Insufficiency
Chronic venous insufficiency is a problem with how your veins are working. Veins collect blood from the body to bring back to the heart. The veins have one-way valves throughout the blood vessel that keeps the blood moving in the right direction, toward the heart. When these valves do not close properly, blood can leak backwards. This can cause a back up of blood in the veins especially areas of the body where veins must work against gravity like the legs.
