There's a big difference between sticking yourself with insulin needles and sticking yourself with intramuscular needles. I do the former several times a day no probs, I tried doing the latter once and nearly fainted.Son was jabbed today. Bit of a move on for him as he wouldn't let anyone stick a needle into him a few years ago. He's T1, and had a really bad phobia with needles from others - OK sticking himself.... went today, all OK. He got over it a couple of years ago, but it's not easy for T1's being 'in control' of 'sticking' themselves....
When came out from hospital with my busted spine, I had to have clot busters - I couldn't do it to myself. MrsF did it...
