I share your concerns also, but the bottom line is none of us want a fracture anywhere. I am a retired RN and unfortunately have expensive horrible Health Insurance since retiring. I would have gone to see an expert at the Mayo Clinic ( I live in South Florida) but I would have had to pay out of pocket because they are not on my plan( the cost would have been extremely expensive) Everyone has a different journey when it comes to taking medication. I am a rare one that no ( 4 total) medications have ever worked for me. My latest MD has encouraged me to be very careful, take supplements, eat healthy, and continue to do my daily exercises. She did persuade me to take Fosimax because she is worried about a compression fracture in my spine. The best way to make any decision is to Educate yourself as much as possible and to feel comfortable with your decision.
