Hi Jane, can't help with the AI's due to being triple neg. I do however post chemo have osteopenia, almost osteoporosis. I was initially put on fosomax, I had quite bad reflux with it(suffer from relax anyway) so I have an infusion called Aclasta every 12 months. My bone density did not actually improve on it but my Dr said that it may have been a whole lot worse without it. I had no side effects from it. There is also The injection that I think Robyn is talking about which is called prolia. Not sure about side effects with that. I think I discussed changing to it but was put off by potential side effects. Can't remember what they are. Robyn have youx had any?
Good luck.
