slammed and locked a finger in the back door of my van years ago, no pain till I opened the door, then I felt it down to my toes. Pain with every heartbeat, GF took me to the sub base medical center where they poked it, blood shot up and hit the overhead work light. Better than getting off, instant relief. Done it twice since then, used a model drill with a wire sized drill, uses two fingers to turn it and one to push from the back, any hobby shop will have them. Disenfect the drill bit first... the hot needle at the sub base med center worked better though.
