Hi there @SueKat , I have severe osteoporosis (three spontaneous rib fractures on three different occasions) and am on femara. Was started on prolia injections over a year ago and will have my third six monthly one this month. My jaw hasn't rotted and fallen out, I've had no legs breaking, no rashes or fevers. I have a number of other medical conditions which each have their own symptoms so it's hard to tell which has been caused by what, but all I can say is that I've noticed no other or worsening symptoms that I had before starting the prolia.
