How much does a finger prick hurt compared to the swine flu shot?

Okay friday im going to get my finger pricked to find out what type of blood i am, the thing is people are telling me it hurts like **** :S i used to be TERRIFIED of needles but last year with the whole school we went for swine flu shot and i couldnt act like a baby so i sucked it up , went and it didnt hurt at all, except after :P though when i got my ear lobes pierced (in march) i was very VERY close to passing out :l anyways so yeah does a finger prick hurt? thanks so much (: & sorry if i seem immature i just worry easily.
