Burning And Itching In The Vagina, Clumpy Discharge, Reddish Bumps On The Labia Sides. Cause?

I have burnin and itching in the vaginal area for the last several days, but it has come and gone. It has not been unbearable. There has also been a discharge but it has not been clumpy. Today, I noticed that there were small red bumps on both sides of the labia; they have not been being there. They don't hurt but did burn when I went to the bathroom. I wore dress pants that are tighter than what I have been wearing the last several days. I was just wondering if you could tell me what you might think it is. Thank you.
