I as so glad you spoke up. I was on the verge of starting Prolia, but checked in with a support group for osteoporosis on Facebook. They put me in touch with two women who had full-blown osteonecrosis. They told me they lost use of their jaws and the osteonecrosis was now attacking other bones! The next time I saw my endocrinologist, I told her I would not take Prolia. She got up and walked out of the room. Needless to say, I will be looking for another doctor to work with me on bone health. I hope you will alert others to what happened every chance you get. Those bone drugs are poorly studied and have little redeeming features once you study them. I am now studying nutritions books such as "Advance Nutrition: Macronutrients, Micronutrients, and Metabolism" by Carolyn D. Berdanier and Janos Zempleni in my quest for knowledge on how to help my bones. There must be a better way - and I think it can be addressed with diet. I wish you all the best luck with your cancer treatment.
