How do I remove a massive splinter wedged under my fingernail? OUCH!

So I managed to get a 1/4” wood splinter jammed under my right middle fingernail. I have cut the nail down as far as I can without making me whimper like an infant. Still, the splinter is barely exposed and I cannot get at it with tweezers. It really hurts and I am considering sawing my finger off, but I figured I would consult the good folks at fluther first. If I don’t get anywhere, I will post the question “how do I painlessly saw my finger off?”
