Thanks for the responses. When I went back on Monday, I told them I was in pain so we started off with 10 minutes of heat followed by the same exercises (I didn't try to push as far) and some new ones like 10 minutes on an arm bike (not sure if that is what it's called) and then sitting on a stability ball straight & then slouching and then over-correcting my posture...it was ok. I still hurt - livable so I'll keep at it. I don't like hearing weird things in my neck. It makes me nervous. I'm discovering that I am now on Misfit Island & it's a bit frustrating...
