Smashed the tip of my finger, what should I do?!

So, I was doing some weight lifting today in my garage and dropped an 80 lb dumbbell on my finger during the last rep of my last set... It became very swollen, and the nail became black. It's been about 7 hours since it happened and I read some instructions online on ways to release the pressure that involves sticking a heated needle into the nail. I did this and a small amount of blood came out, and the nail doesn't look nearly as black, but the swelling persists. The bottom of the tip my finger is swollen so it looks about 25% larger than the other finger.

Should I take the needle deeper into the nail to relieve the pressure? I'm personally thinking no because the darkness in my nail has lessened substantially so therefore I think that most of the blood I can draw has likely been released, although the pressure in my finger is keeping me from falling asleep...
