What a great update. I'm so glad you let us know you are feeling so much better. Isn't it amazing the difference a couple of weeks make? That you could do 8 hours of shopping and not get tired, is much better than I could do and I never had heart problems. Are you feeling better than you were before surgery yet? THAT was always the time that Justin would get really happy about. A couple weeks after one of his surgeries he was going to a friends house a couple blocks away, he called me shortly after he left (and of course when I saw him on caller ID, I braced for bad news) and it was to tell me, he realized he was running a couple of the blocks and didn't even think about it, but then realized he hadn't been able to even walk that far before surgery without getting out of breahtha and wanted me to know now he could run with out a problem.
I think if it were me, and rehab didn't return my call for an appt after 2 weeks, I would call them back, just incase they lost your message.
