helpful reply; I've been on Tymlos 1.5 years and am eager to find out my newest Dexa as I have to switch out after 2 yr marker this fall. I'm in the -3.3 range/spinal too...so am hoping for a big improvement; play pickleball almost daily and lift, etc. but have already lost 2" in height and I'm only 64! Appreciate the readings/video referrals...will get on it and be ready!
