It occurs to me that I never did post the requisite update about my MRI. It was "normal" per my doctor. That's all she said. Normal. Oh, and she tossed in a line about taking that last prescription she gave me. No mention of how there wasn't bursitis and there wasn't anything to indicate why I was in severe pain during the MRI and what the next steps might be other than "Here, have some more drugs."
Also, it's a very good thing I got a copy of the radiologist's report on my own as my doctor didn't think it worth mentioning that I had several benign ovarian cysts that need a follow-up via ultrasound in 3-6 months to make sure they remain benign.
Needless to say, I'll be cancelling my follow-up with this particular doctor and investigating other options for addressing whatever the hell is going on with my joints.
