Ouch. That must suck.
I'm guessing they had a hard time finding your veins?
Ohh, and funny blood-related story: My health teacher told us that oxygenated blood is red and unoxygenated blood is blue. That's why there are veins in our hands and arms that are blue. Apparently in one class he taught, this kid said "That's not true! I cut open one of those blue veins and the blood was red!" My health teacher apparently then told the kid that by cutting open the vein, he let oxygen into the blood.
