*TMI* lump under outer vagina skin that doesn't move

Karri

So, I've been having this sore like after sex feeling for the past two days and I haven't had sex in a week. Last night I noticed a very hard lump under the skin, and it doesn't move, nor does it have color too it. It honestly feels kind of bone like.

Any clue what this may be, please help, I'm freaking out.
