I think your approach is wise, and getting info on bone quality is also wise. I am surprised you were medicated at -2.5. My doc won't use Prolia because it is so ricky to get off in terms of rapid bone density loss (unless you go on Reclast). We are all between a rock and a hard place. I have been told bone builders should come first, not Prolia or bisphosphonates, but you would probably not get insurance coverage: your scores are too good.

Dr. Keith McCormick, a chiropractor expert on osteoporosis, might be a resource for you. He wrote "The Whole Body Approach to Osteoporosis" and "Great Bones" and does phone consultations (first one is $300). I am often a proponent of meds for those below -3.0 but in your case, maybe not! Getting info, testing and opinions seems like the best course and you are doing that!
