Vaginal infection???

Hey, I'm going to the doctor tomorrow but I'm freaking out so I want to be prepared in case any one has an idea of what this could be. 
I have a very red, swollen vulva. It burns when I pee, not every time, but most times. The area near my clitoris is especially itchy and it's painful to touch. What could be going on??? 
Also this has been going on for about a month now. It's really bad now which is why I'm going to see the doctor tomorrow. I feel like it all started after I used a summers <a href="">eve</a> wipe, but I don't think I can have an allergic reaction for this long can I?
