Did that when I used to work in a wedding gown factory. The needle was quite sharp so it didn't hurt going in. As soon as it happened the finger turned white on the end, lack of cirulation, I think. Very first thing that went through my mind was, "Boy! That's gonna hurt in a minute!" It did. Lot's of blood, but not as bad as if it had been a dull needle. (Another reason to make sure your needles stay sharp!) I was at work, so couldn't wallow in the pain. Doctored it up. Then put a bandaid on it, and back to work. I think continuing to work might have kept it from getting stiff. Needless to say, I have develped a great respect for sewing maching needles. That was 15 years ago. They don't bite me anymore. Hope I didn't just jinx myself.
