Vanna, I have no words of wisdom for you. My PM doc does all the prescribing for my narcotics, and Lyrica. My primary does the prescribing for any "stupid" things I do like breaking parts and pieces. I have also gotten narcotics from a surgeon when I had multiple breast biopsies. I also have a psyc doc who prescribes antidepresants (currently Pristiq). All of my "extra docs" send info to my primary. I think as a PAIN MANAGEMENT doc he should give you meds for breakthrough pain. Try to explain that you cannot afford the other treatments, see if he can/will help you out.
