Smashed finger question?

A little over a week ago I smashed my finger putting a log into our fireplace. The entire nail is purple. I did not drill a hole to relieve the pressure, I really didn't feel the throbbing sensation. I tried to go to the doctor that night, to an urgent care center, but they were already closed. I didn't want to go to the ER, let's face it, my smashed finger wasn't going to be a very high priority and I didn't want to be there all night. The next day it felt a lot better, and after a couple days the swelling went down and I got the feeling back. BUT NOW, I don't know if it is because of all of the blood that is under the nail, but the nail has started to fold in or curl in on the sides. It is my ring finger, but from the top view, the nail looks skinnier than my pinky nail. The sides of my nail are squeezing my finger and it hurts. Is there anything I can do at this point? I realize now I should've used a needle to make a hole for it to drain the blood, but I'm so squeamish, I couldn't bring myself to do it while I was in that pain. I'm afraid I'm going to end up with an ingrown nail because of the pressure on my skin. Is this normal for a smashed finger? Is there anything I can do?
