Itchy Vagina

So I'm not sure if I'm posting this in the right group, but I need help! My labia and clitorus area has been swollen and sensitive and a bit itchy. At first I thought it was just from over stimulation. But the itchyness has just gotten worse. I looked and the inside of my vagina is lumpy. Nothing on the outside, just the inside. The bumps have now spread to the inside of the labia. No discharge. No burning sensation when I pee. Ive looked and looked on google and I cant find anything. I'm going to call the OB when they open (tomorrow is a holiday), but in the mean time I need some relief. I just got done with my period yesterday & I believe the I started feeling discomfort 2 days ago? HELP ME PLEASE!
