I recently found out that I have Osteopenia, -2.2, and my doctor had recommended Prolia. My insurance would not pay for it so she then prescribed Boniva, orally. I took one dose and the next day had the worst back pain I have ever had. I will not take it again and after reading about Prolia I don't want to take it either. I am 61 and outside of living in Nebraska where we have ice quite often, I am going to take my chances and try eating more calcium rich foods and doing some weight excercises. I used to think that if a med could fix things I should go for it but I have experienced side effects more often lately and I am done with them!.
