I Had Bifemoral Stent Replacement On Sept 22 And Everything

I had bifemoral stent replacement on Sept 22 and everything seemed to go well. I teach 7th grade so I am on my feet all day. I noticed yesterday when I got home that my ankles and feet were swollen - especially the left foot and ankle (the side of the worst blockage). This morning they were back to normal, but now my left ankle and foot are swollen again. I don't know if this is something I should contact my cardiologist about, or if I should monitor it for a few days first.
