Can you diagnose me?

ok, this is all about ME. I have had a myriad of severe symptoms since Labor Day weekend; nausea (which I thought was from my birthday celebrating :) ) abdominal pain, shooting pains under both ribs like a cramping pain at different times, abnormal distention in my stomach and then dull, throbbing pain in my lower back area. I knew since I have already had an endoscope and been diagnosed with GERD that maybe the symptoms were related to that. I actually went to the Dr. Monday, and she did a cursory examination, paid more attention to my blood pressure issues (which I am borderline) than the pain in my back which at this point is so severe I cannot sit for more than 30 min and have trouble walking. Her diagnosis? sacroiliitis She prescribed Flexeril a muscle relaxer which I can only take at night and celebrex, an anti-inflamatory. Now I am no Dr. (I just play one on the internet) but I have no fever and the severe bloating pain has nothing to do with this diagnosis. To top it all off, I haven't been able to try the celebrex as my WONDERFUL Anthem insurance won't allow it until I try two more alternatives that are...cheaper. One being Advil! If Advil helped I would never have gone to the Dr.! So now I am playing phone tag with the Dr office trying to at least get the prescription filled to see if it helps, as the Flexeril certainly doesn't. I also had to ASK for a urine test to rule out a kidney infection. The Dr. office called my home number today asking that I call them. Of course I got that after hours once we got home from work. I bet that they are calling to inform me I have something showing up in my urine/bloodwork....hmmmmmmm you think? gotta go lie down..Sigh.
