thanks for your response, Janet! I'd say my ribs are probably the least affected,,,,,although I am having huge problems lately with pain in my shoulder blade radiating down my arm to my elbow (It feels like sciatica only in my arm),,,,,

I dont think I've ever had an xray of my back/spine at all,,,,,,,I've had MRIs of my lumbar region, but I do not know if that would include the SI joint or not,,,,my last MRI was at least 2 years ago though,,,,,possibly more, it's so hard to remember,,,

the nurse said they'd take a ton of Xrays, though, so hopefully we either find it,,,,or rule it out.

thanks for responding smile
