I'll add on to the other comments to say that I was also pretty nervous the first few times, since I was used to anything needle-related being really painful for hours after (from the thick needles used for drawing blood, or vaccines). That went away pretty quickly - the 30-gauge needles I use are so thin (and only poking through a little bit of tummy fat) that it's pretty much painless. I still freak out when getting blood tests, but E injections are no problem anymore :)
