I thought that Forteo and Tymlos did not work to stop bone loss after Prolia. You are in a bind because you have done bisphosphonates already. Both Prolia and bisphosphonates are anti-resorptives and the effect of those (atypical fractures) can occur if taken too long.

Someone posted a video with Dr. Paul Miller the other day where a bunch of endos discuss meds and they said that preliminary studies show that Evenity can stop Prolia rebound. Personally I would try to convince the doctor to try Evenity- or find another doctor. It would seem, from what I have read and been told, that you don't have any other good options.
