Oof. True… I don't quite like either. The first time I had my blood drawn, I pretty much freaked the nurse out (he was new and nervous and I was crying making it clear I didn't fuckin like needles). Apparently, I freaked him out so much that his hands were shaking while he drew my blood, which led with a huge nasty bruise right there on my arm and that bruise grew until I was like half-way up my bicep before stopping and disappearing after a few weeks. which by the way, a bruise should not grow that big after you get your blood drawn unless the person fucks up
And before anyone asks, no I did not tense my arm up at any point. I'm a masochist, I don't mind pain, so my muscles actually relax instead of tensing up like a normal person would.
Anyways yeah, that was my needle story. Sorry if it freaked you out.
