I’m Very surprised that your Dr. told you just the abdomen. Even back in the cavewoman days, I was told to rotate, rotate, rotate every shot, in the arms, abdomen, thighs and bum which I did for many years with the exception of my thighs. Bad experience there.
I found myself eventually just injecting in my lower tummy and arms. I never got any lumps under my skin but I did get a really soft, fatty tissue in those areas(again no lumps). Then one day, the fatty tissue disappeared and I was left with dents in those areas instead(Lipoatrophy). This was about 38 years after I was dxd. and 6 years after I had changed Insulins. I mentioned this in the Complications section but I noticed it was all deleted.
Anyways, I stopped injecting in those spots for 6-12 months and started injecting in my “dreaded thighs” and butt to give my arms and tummy a rest. I got used to giving it in
The dents disappeared in my arms and the left side of my tummy but that dent in the right side of my tummy obviously won’t ever go back to normal.
You should get better absorption also by rotating instead of staying in the same areas. So for heavens…ROTATE. =)
