Thanks for the response! I really appreciate your outlook on things - it makes me feel not so alone in this

I'll give him a call and ask if I can skip the 24-hour UPEP this time, since I just did it in January and it showed nothing.
Did you ever have your glucose tested?
I think I'm doing a skeletal survey because the wait for MRI in Canada is insane if you are not considered high priority. I waited 9 months for a knee MRI (which healed by the time I got it anyway), but only a few days for a brain scan when my inflammation was acute, and 1 month for a repeat brain scan. It varies, but I think a whole body MRI is too time consuming for them, or something.
I was actually thinking about the skeletal survey yesterday. I had a lot of xrays done this year on various parts of my body that showed no abnormalities, so at least I know my chest/ribs, skull and knee are clear! That leaves arms and the other leg. Those parts of my body I actually have no problems with, so I feel more OK about this.
I will look into DEXA. Thanks again!
