I have just been diagnosed with a bladder infection. In my culture there was red blood cells. I dont know if those have any thing to do with this. But today I went swimming in my community pool. As I was in there, my labia minora was starting to feel irritated and hurt some. When I got out of there, I went to the bathroom and saw a little red bump. I know its not a STD, but I was wondering if it was anything serious. Ive been searching and read people having pimples or little cysts or blood blisters down there. Im too scared to pop it. Help please!
