I smashed my finger with a game at work and my half my nail is black and blue. What should I do?

I smashed my finger with a part of a game at work and now half my nail is black and blue and my cuticle is swollen and squishy. It doesnt hurt anymore, just when i put pressure on it. But it's really ugly. Everyone at work tells me to heat up a needle and poke a hole in my nail but I read online that it can get infected that way. Any thing I can do besides go to the doctor?
