I'm in the same boat. I'm 57 and have been dealing with spine issues and have had neck surgery. I just found out I have osteoporosis and osteoarthritis. Im worried about my fusion holding up because it says to avoid surgery if you have Osteoporosis and mine I was told was bad. They suggested the Prolia because I have stomach issues and Esophagitis. My dentist told me to avoid Prolia if possible and stick with Fosamax because of issues he has seen with jaw bone and teeth. He also mentioned issues with the hip bone also. I'm so scared to try any of it but the doctors said I really need it. I don't know what to think or do. Please let me know what you hear and what you decided and think. I should have been on something a long time ago but I've been hesitant. God Bless
