@jennirdh did your doctor warn you about the strong Prolia rebound, which results in a decrease in bone density and more importantly, increase in fracture risk? Ibandronate (Boniva) is not recommended by sources like Keith MCCormick's "Great Bones" as the best approach to counter that rebound. If you were on Prolia for awhile, Reclast is recommended and if you were on for just 1-3 shots, alendronate (Foasamax) might work. My doctors won't even use Prolia because of this rebound risk. Tymlos will be a good drug after fractures in my experience.

Not trying to cause regret here. Just posting because you mention getting back to Prolia and in consultation with your doctor, maybe you can come up with an alternative to protect your gains.
