This Morning's Blooddraws

As 'usal, this morning I had to get a blooddraw. I waited at Quest Dianostics, where I get my bloodwork done at, for about 30 - 40 minutes or so. We rush in, and I get two little tubes full of blood. Two. TWO! I was supposed to get THREE! SO, I had to get aanother one later. Lucky it didn't matter that I had eaten... The lady at the second place (which is closer to my Mom's) was really nice. THE BLOODDRAW HURT SO MUUUUHHCCH1!!!!@!@!!! the 2nd lady said I have a knot in my arm (bloodvesle).
Does anyone know what that means?
