Gary, since Jo and I both know what you've gone through, we know how you feel. I can't help but remember what the Doc told me just before he started cutting on me..... "when you wake up, the pain you had when you came in this morning will be gone. It will be replaced by one 10 times more painful! BUT, this one will go away!"
Hang in there, do all the exercises, and you'll be better than new in a couple months.
