Have you seen your regular doctor and talked about the pain? It could be that blood/urine tests or others could find a cause that could be worked on to ease the pain.
It sounds like you and your pdoc are not having a very useful dialog. If something worries you or you don't like it or wonder at what he's thinking/doing, you should ask him about it. I'd tell him what you like and what you want to accomplish (address the affect) and keep telling him if he doesn't seem to "get it".
The poor doctors only see us maybe 20 minutes every now and then; I've been seeing my regular doctor 4 times a year for over 5 years and he still gets my last name wrong on my prescriptions :-) But over the year, when we are together for my actual appointment, we don't "argue" as much because he "remembers" me and I back up what I want/say/claim with actual medical papers I bring him :-) We have an okay working relationship now, despite his not knowing my name
