I have a small to medium sized bump on my labia. It looks like it could be a few of them clustered in one spot. The other side of my labia is small and not swollen because that side appears to be normal. When I scratch the red bump I immediately have white discharge come out . The discharge is thick and white, and sometimes white and slimy. It burns when I urinate. I always had pain when having intercourse and the inside of my vagina seems or feels like its swollen. What could this be?
