I was always up for anywhere really before the pump, but it wasn't until about 8 years in to my diagnosis that I started using my stomach......
this was likely down to the fact I was very slim as a child, unlike now, where I would eat anything put down in front of me......
When you look at the needles used today and even back then, they are tiny, and if you get a fresh one on as much as you can you just don't feel anything, so anywhere was fair game.....
Don't think anyone's mentioned this so far but how about calves? That is the only place I won't inject in. I remember being on a 'BDA' camp when I was 8 - in the Outer Hebrides no less - and they asked me to try a new site. Just don't it "knacks"!!!
I have just been prescribed insulin at night (am Type 2 with meds). Did try and explain I am needle phobic. Only solution, my wife does them around my bottom rotating and changing position, am next trying arms again from behind so I cannot see the needle. Yes I know it is only a little needle, but a needle none the less. Use the idea of rubbing the area first with an ice cube really does help, which I believe her indoors read somewhere on here !!
