Varicose veins are large, bulging, blue, rope-like veins in the legs. They can occur when the valves in the leg veins become weak or diseased and no longer function properly, causing blood to pool in the legs. Varicose veins are the most obvious and visual symptom of vein disease, but you do not have to have visible veins to have vein disease.
