I have a loose molar and the gums under it hurt every time I bite, What should I do?

I have a loose molar and it hurts like CRAZY !! and I'm thinking about going to the dentist but I just want something to heal the pain or decrease it, every time I bite it REALLY REALLY REALLY hurts and I tried to pull it out but I couldn't stand the pain at all so I stoped, any ideas on how to make the pain go away or decrease it ??
