Now I'm going to have an echocardiogram (resting, not with stress). I guess depending on how that looks they'll decide whether a catheterization is needed. (AKA angiogram.)
I can tell things aren't normal because I am looking longingly at scooters, wishing I could have one. I would get out more and do more things that way. But I'd rather get my arteries opened so I can walk again.
