Actually, NO ! You are almost implying that we get some kind of sadistic pleasure from the use of needles - wrong !
Speak for ya'self, its the only bit of fun I get these days. Think how much fun Mac the Knife gets- he gets to use knives as well. (Where is grumps these days, I've had to revert to arguing with my wife.)
Joking apart, I'm pretty the sure the procedure involves a "pin prick" sample rather than venupuncture ??? (Simillar to the device used by self-monitoring diabetics.)
In this case, desensitisation could help.
