Had Blood Clot In Iliac Artery (removed( - Also A

had blood clot in Iliac artery (removed( - also a cardiac patient (3 heart attacks and double bypass) every since the blood clot removal I have had SOB and sever leg heaviness in both legs now and stairs are a killer - redid ultrasound (I was afraid that the stent was blocking) everything in the legs and Iliac looks good (some minor blockage in left leg but they say they do not think that is the problem)- but yet it seems to be getting worse - also have been having pain on left upper quad (for years now) and that has gotten worse - any thoughts would be great appreciated thank you female 52
