I started a reply, but then lost it somehow, so apologies if something appears twice.
I have read that no one is exactly sure how Strontium works. It appears to fill in where bones are lacking, and this does improve dexa numbers....but what does that really mean for strength and flexibility? Bones have to remain flexible enough to take stresses without cracking, splintering and breaking. In my head I compare it to tires on the car. An old tire with a patch is fine and functional for a while, but a new tire has much more strength and will last a long time compared to the old one that has been patched. Since I'm taking Tymlos, I'm supposed to be building new tires...I mean bones (time will tell on that one).

I would love to have a REMS test, but none are offered in my area. I am seeing a new endo at a university who specialized on osteoporosis. I will have to travel to see her but am ok with that now. Hopefully the university has REMS on their machines.
