Took me a long time to get the art of injecting down to a "t" even after watching my mum inject for years. My doc or CCG or some pen pusher tried to save money and flob me off with a low cost needle, well I tried them for about a week and then went and moaned to the staff manager at the surgery, she was very understand, which made a change, and got me back on my hospital issued needles - BD Micro-Fine Plus with "penta point" I once got the same brand but ULTRA not plus and they made me bleed a lot but with PLUS am ok, I still bleed every now again but like others I have said rotate sites and go slow they should go in like a hot knife through butter - talk to your doc or nurse about changing needles
