Grace,
It's easy for people and doctors to "know" that we don't have pain based solely on studies. Ask him this... Does he live inside your body? Does he have Crohn's? Then he can't possibly know how you feel.
I've had the pain med battle myself. It seems most of us have been on antidepressants at one time or another (there seems to be a link to serotonin reuptake inhibitors assisting in Crohn's). We *do* have pain. It's literal. It's there. Ask to see this so called proof that he has that we *don't* have pain.
You very well can ask for copies of your tests, his notes from your appointment, whatever you want. The internet is a great tool for research. Plenty of reliable medical sites out there for people to research their test on their own! They are your records about
your body....you are most definitely entitled to them!
But please try to find another GI....you don't need this stress in your life. We aren't drug addicts, we're just trying to make it through each day without being in pain. Is that so much to ask?
Best of luck,
