okay, just a couple days ago I started getting really itchy on my vagina. And I haven't used a new razor or anything. but today I was itching and when I went to take a shower I took off my underwear and saw a few blood drops. So I decide to look in the mirror and I saw a portion of my vagina really swollen like a bubble. i put ice on it and its not going down. But it hurts to walk not bad. It's more uncomfortable then anything. Does anybody know what this is I have?
