I agree the sight of the needle was enough to make me nearly faint!! I got mine from the chemist and opened it at home so I could check it out (left everything in wrappers) The insertion thingy was in a clear wrapper and oh boy I thought I was going to faint!!! Anyway I have survived two now. Yeah it hurts for a few days. Mine even bleed for a bit but once the bruising goes it should be all good.
