Suggest Treatment For Bone Fractures

Hello, I have had fibro for 20 yrs. I have had 3 bone fractures in the past 6 mo. We have found that my vit D is 20. I been placed on vit D 2xwk. I was on regaland for naseau (Ulcer),which causes fractures, was on abt 15 mo.

I am pre auteoporosis, from bone density dec.2010.

What kind of bloodwork do i need? And what supplements/ rx drugs do i need in your opionion ? I am looking for answers and the direction to go here? Have there been any studies on fractures with no injuries, and fibro?

thank you jan
