I've been using the pens for a few months now after switching from the syringe (I didn't ask to change, it just happened when I switched from the hospital supplying them to having the Healthcare at Home people delivering them) Anyway, I see in the leaflets with the pens and on the website it says to pinch the skin, however when I was trained up by the nurse she just placed the pen straight on to my leg and injected without pinching, so for the past couple of months I've injected without pinching too. I've never really thought anything of it til now but for some reason today I'm feeling paranoid about it..
