I Had Angiogram On My Right Groin & Stent Placement

I had angiogram on my right groin & stent placement via right radial artery 2 weeks ago. I still easily get tired & slight SOB. Now my right leg is edematous but no calf pain. What is happening? I called the doctor's office & advised to just rest & elevate my feet with pillow when lying down & if it gets worse to call back in a few days. No redness, drainage & swelling on both sites of insertion. Help.
