@goseve with 7 spinal fractures I am here to say that for me those fractures have been a lot worse than any side effect.

I got on Tymlos by starting at a low dose. The pen has "clicks" that measure dosing. If you are afraid you could talk to your doctor about trying that but get yourself up to a good dose as quickly as possible.

People seem to have few side effects on Evenity in my circle of friends. Ditto Reclast. But they are not on the forum!
