Joys of Testing

I get to spend an exciting day tomorrow at the cardiologists' having a stress test and a nuclear stress test done.  Hopefully we'll figure out why my chest keeps hurting, I'm short of breath, exhausted all the time, and retaining tons of water (worse than either of my pregnancies, though I retained so little it wouldn't be hard to retain more).  At this point, I'd be happy for them to find something wrong, just so we know what's going on, and can maybe do something about it.
