You need to stay on task with those balance exercises, Deb! A lifesaver for many. Have you, or your Dr recommended more visits with a PT person? I can't remember what started your balancing issues anyway, the surgery last Summer stopped them for a while, right? I know ONE thing about PT, it WORKS, but you have to do it on schedule. I'm a true believer in that. 
Actually, the PT people said I'd "graduated" and could manage on my own from there on out. One doctor thought some more PT might be helpful, right after surgery, but I think I'm getting back to where I can manage the exercises at home, if I stick with them.
I've had some setbacks in doing that lately: a cold, and headaches, where I just didn't feel like doing the exercises. I also AM supposed to take naps and rest with my feet elevated, to relieve ankle swelling, so I don't consider naps "goofing off." They also relieve headaches.
But I hope I'm back in the swing of things now. I did a good number of exercises yesterday, and then every single one today, even though my PT schedule never called for doing them ALL on one day. They cautioned about overdoing it. But I'll keep plugging away at them.
As for actual PT in the clinic: that would require a long drive (25 minutes each way) each time, and as I just indicated in a previous post, I'm having a hard time getting out to get into my car on the sloping driveway, still, since surgery made my balance worse, somehow. And Maureen couldn't go with me to PT, because there's no place for her to wait up there. So I would want to be able to drive myself, alone, before (if ever) I went back to PT.
I do think the machines in the clinic might be helpful (like the leg press), but that's not an option at the moment. So for now, the best thing to do is keep working on everything at home.
