You have osteoporosis, as you stated. The WHO recommendations are that you take an osteo medication to reduce your risk of fracture. Many people think it's all about the T-score, and if that improves or worsens, that's what's important and how bone health is determined. Not true. It's about your risk of fracturing and the T-score is just one indicator.
By itself, T-score can determine the need for meds if it is in the osteoporotic range. People with "just osteopenia" need meds when they have the presence of another risk factor, such as a prior break, steroid treatment or a low FRAX score.
Orthopedists, as a whole, do not monitor or treat for osteoporosis. You'd think it was a no brainer for them, but they don't. Mainly because you don't see them on a regular basis, and if you're on treatment, you need to be monitored.
Your risk of fracture is much much greater than any side effects of the meds. I really wouldn't worry about the jaw necrosis (if it happens, the bone does regrow, just slowly) or the femur breaks. Much hype and fact that people not on the meds have identical fractures is not publicized.
If I were you, I'd take the medicine. If you have a compression fracture, there's no do-over. You also need to avoid any forward bending of the spine and twisting of the spine. Go online to the National Osteoporosis Foundation website (
www.nof.org ) and order their booklet "Boning up on Osteoporosis." We use it as a teaching tool for our rehab classes. It has a lot of verified proven information and gives you illustrations of moves to make and avoid.
Take your med with 1200 mg of calcium, 600 at lunch and 600 at supper and 2000 IU of Vit D each day.
