I totally understand your frustratations. I really wish that doctors would get a clue and it is really frustrating when those doctors who know us best and who we trust let us down. Going through a similar but different situation with my PC doc where he let me down in a lot of ways...and the man was the one who delivered me in the delivery room for goodness sakes. But he referred me to someone who I think (hope) will be a good fit for me as a pain management doctor in the sense that at least she cares.
I hope you end up with a good pain management doctor. I know how frustrating it is when you have to start all over with a new doc. I've had to tell me story to so many new people in the last month (and can only look forward to telling it more if I get admitted to the hospital). Hang in there. My thoughts are with you and I really do hope you get a good doctor who understands the pain you are dealing with and who is really interested in taking care of your pain.
