I had similar problems when mine were growing in, though your pain sounds much worse than it was for me. You should probably see a dentist. I personally didn't want to have them removed because I don't like the idea of doing unnecessary procedures, and my Dentist said I have room for them. But if your in that much pain, you might have a gum infection or something...definitely see a dentist.
Oh, two years ago? Well, maybe this will help someone else then.
