Thank you for the postive energy. and sending postive energy for you to educate yourself as best you can. I recommend the book 'Great Bones' by McCormick - excellent referecne and hopeful! Try to find out the cause of your OP - and that will help your healing.

I took the full course of 2 years of tymlos . MY understadning is tymlos usually is recommeded for 18-24 months. I should have stopped at the 18 month mark as I have a cortical bone thinning problem in my feet. Tymlos and forteo ( both PTH) work primarily on trabecular bone and can cause in some instances, cortical bone loss.
I had good gains in spine ( having alot of trabecular bone) on TYmlos but negligible in hip and nothing in forearm. My feet actually got weaker on tymlos but that is due to my particular situation. I took short course of Actonel to stablize after tymlos and now have moved on the Evenity because my P1NP was very very low and I need more bone buildnign/anabolic support. Evenity has some possitve effects on cortical bone.
Good health to you!!
