I hate having my blood tested too! It stinks, right?
Well I LOVE my pump and my infusion set, simply because it makes life so much easier..but thats a different story. :)
So, onto the infusion set. The way most sets work (or at least how mine works), is the thin and tiny needle that puts the site in, has a little plastic canula around it so small that a mouse wouldn't be able to see it. (Well maybe they would...but you get the point ) After the site is in, the piece/mechanism and the needle that inserts it is removed and the canula stays in you. For me, I can only usually feel the canula for about 30 seconds - 2 minutes after the site is in me. If the site hurts for about 5 minutes or more, I take my site out (simply just peel it off like a band-aid) and put a new one in. Most of the time nothing is wrong with it; maybe it just hit a vein or something. Other times however, it may bend while going in. That is the only time it hurts, but once I take it out, it is ok. When it hurts, it feels nothing like getting blood drawn. This is so small and I bet that if I chose not to take the site out after about 5 minutes of hurting, I would forget about it, whereas I think blood tests hurt a lot, and I would never be able to just ignore it. Usually, it doesn't hurt though. Normally I just put my site in and go on my way.
Anyway..my point is....that sometimes the canula in you may hurt a little bit, BUT when it doesn't hurt...theres no other way to put it I guess besides it doesnt hurt! I can never really even feel it in me! It's so incredibly small and thin and I can never feel it in me. It feels completley different than a blood test because you feel a blood test, but you usually don't feel a site!
Hope I helped!
