I don’t have answers, just prayers. But I do have experience with my husband and compression type spinal fractures. We went to Mayo Clinic for his multiple myeloma, he has done two years of arhydia, not sure of spelling. Also much higher doses of vitamin D. My husband is on a 5 lb limit for life and he is careful, but he walks almost daily. I would encourage you to seek out a doctor specializing in bone health. My heart goes out to you.
