Isn't there some long term harm to the skin if you do this often?
Insulin users would have better answers to this question, since they might inject multiple times a day, whereas GLP-1 users typically inject only weekly. But in either case, the answer for subcutaneous injections using needles sized 29g and smaller is no.
I’ve been diabetic for 30 years, and for more than twenty of those I did multiple daily measurements by pricking my fingertips and multiple insulin injections per day. Now I wear a sensor that I replace every two weeks and a catheter (which I change about once a week).
I really don’t understand this phobia of needles at all. After two days with one system or the other, you get used to it—there’s no pain, it’s just a mental issue of “having to make the gesture.”
