thanks Daniel! The 26/28 you mentioned would be bigger than the 32 I am now using. The one I had the 28 and it was bigger. I had cervical spine surgery last year and it is hard to move my head downward to inject in my tummy. I might try again since acquiring this nano ultra fine pen. Another issue was the medicine seemed to make my tummy expand. A lot of the gals injecting the Tymlos seemed to feel similarly. I have a very steady hand. I just can't move my head to see my backside or the back of my arms. but so far so good with the legs! thank you, Lori 💐🙏🏼🥰
