due to thyroid issues? Do you have hyper or hypo-thyroid? It mite be an auto-immune thyroid aspect which is the hyper/hypo thyroid going one step further...take a look at the autoimmune disorders forum further down the list. I have now an auto-immune related thyroid connected to other Auto-immune issues...It's confusing for sure, but there are lots of us all around the boards! Don't despair!
I too am going thru the passage from osteopenia to 'porosis'...Partly due to my issues but also my meds for them...It does sound like your docs are on top of it! - j
