                        Find a good pulmonologist (or any good internist) in your area.  Thrombosis are nothing to mess around with.  I have had 3 diagnosed deep vein thrombosis and 2 of them moved to pulmonary embolism.  I now take warfarin daily and have a vena cava filter inserted to aid in prevention of clot movement.
