@kentucky606 - it is eerie how similar our situations are!
Recently, my PCP of several years just took early retirement due to medical issues she was having. She referred me (and her other patients) to another dr in the same office. I met with him for the first time, and I was very concerned that he would not treat my pain or take my complaints seriously.
Instead of directly asking for the medication, I told him how the pain was impacting me (can't sleep, can't leave the house, etc.). I asked what he could do to help me, and let him take it from there. (I did have one request because of a drug allergy on a medication to avoid, but that is just me.)
He and I have had a good chat or two since then about the politics of pain and medicine. There are both federal and state laws, not to mention insurance interference, that come into play.
I'm surprised that if you were seeing a dr in that same practice, then they would have all your files and you shouldn't be treated as a "new patient". Did you ask why they were unwilling to write you a pain rx? If so, what did they say?
