What's wrong with me?

My vaginal area always burns, it has been going on for four days. Its a very uncomfortable burning. It's all I can think about I've been miserable with it. Sometimes in the middle of the day it will go away for awhile but when I wake up its back again. I think it could be a bladder infection. It always burns, I feel like if I pee it will get better but it doesn't, when I'm done peeing I get this feeling that I have to go more but I never can. And my pee seems to be a little smelly. Please help urgently.
