Hey folks,
This morning i shut my index finger on my right hand (plucking hand) in the car door

It has been throbbing with pain all day, really is killing me. It isn't broken, i can bend, it but it hurts like hell. The nail is now black, well underneath it, which is blood i presume. My sister says i could put a red hot needle through the nail to release the blood, thus probably stopping it hurt as much. The problem is i have a gig in a few days, i really dunno what to do

??
