What Does Bumps In Vagina Indicate?

Hi, I was wondering if there was something wrong with me because, last night I was out with my boyfriend and he started fingering me but when I told him to stop because it started burning a lot. I told him I was dry. When I got home and looked down there, it was swollen and when I examined myself inside of my vagina, there was a bunch of swollen "bumps" type things. I dont know how to describe them.. but it hurts, and its still there now. What can I do? or What do I do about it?
