Hi Sanober!
I think some amount of bruising is normal. I have a really nasty bruise on my thigh at the moment from one of yesterday's injections. For me, it seems to happen if I catch a capiliary or something under the skin - it's just pot luck I think. Sometimes it hurts, usually it doesn't. Sometimes you bleed, usually you don't. Sometimes you bruise, usually you don't. I find the stomach particularly sensitive, uncomfortable and prone to bruising. I really don't have any fat there to pinch (sorry ladies, but it's true :lol: ), so I use the side area around my waist when I have to, but avoid the front stomach area altogether. As I'm gradually having to do more injections, I'm finding the whole rotating of sites very problematic. As Andy said, make sure you're on the shortest needles if possible. They started me off on the 5mm ones and I bruised more with those than I do since swapping to the 4mm ones. Be careful if you inject at an angle, though - I find it stings much more and doesn't work aswell - I suspect I don't get the needle in deep enough sometimes.
