I used Forteo when the recommendation was to use it for 18 months. I had no issues with it and had great results. I tried Reclast after that and had terrible jaw pain. I had already tried all the other bisphosphonates and had terrible side effects. I did fine for close to 20 years. Now I have severe osteoporosis...again. I had some pretty ugly pain after my 1st Prolia injection. Not sure what to do now.
