Like you Riverwild I just started PT last week.
So far so good.

I spent most of the time between the parallel bars trying to stand and walk without doing my weeble imitation.
The exercises to strengthen my left arm actually felt good.

I was a little sore the next day, but not too bad.

Unfortunately, the therapist and I have decided that I must give up my dreams of becoming a prima ballerina.

I wish I could find a water exercise program.
I really would enjoy that.
Best of Luck to you and hope the therapy helps.
