Ok, I spent the last three days at MEPS, a facility run by the Armed Services, which is intended on assuring that the people going into the different branches of the military are nice and healthy. Well I had to give a blood sample; I've always been horrendously afraid of shots, having only had about one or two in my life and I was terrified of this one, I got it out of the way somehow but now my arm hurts really bad, and the blood was taken about 15 hours ago. Kind of ironic that I have to ask this, my new position in the army is health care specialist, but for now I'm clueless and want to know from someone with experience, is this large amount of hurting normal?
