Help!

Okay ladies I'm freaking out I woke up this morning with a kind of aching pain around my vagina and I just brushed it off for a couple hours as I just slept weird but I just went to wipe after using the restroom (which caused more pain) and there is a cyst like little bubble on one of my lips. I have no clue what to do! Go to planned parenthood? Emergency room? I've never had an issue like this and I have no clue what it is.
