I am sorry to hear of your pain. Agree, nobody knows the true long term effects of these drugs. I told my doctor my body is telling me something with these side effects, she said all drugs have side effects and we can argue forever over it. I have taken calcium, D3, K2 for decades as well as exercise and still have severe osteoporosis. Mine is more in my femur and lumbar areas; all osteoporosis. Every one of these osteo meds have side effects, some are really bad: jaw decay, stroke, heart attack, dizziness, bone/jt/muscle pain, and can fracture once off of them. These meds are lifelong, once you start one, have to be on it or another forever. I don't know if that is good for me either. I wish you well too.
