painful bumps? please help!

someone help!
i have super painful bumps on the lips of my vagina and even in/near the vulva. it causes EXTREME discomfort to pee and to the touch. 
i have a boyfriend who im sexually active with, but we've been dating for over half a year and this hasnt been a problem until last week. i originally thought it was a uti (feeling like i had to pee all the time) but now i dont feel like that, its just these bumps that are killing me.
the only thing i can think of is that i stayed in a pretty low end hotel last weekend and maybe the soap/other irritated the skin there...? i have no idea, but i'm freaking out!
also i cant really go to a gynecologist as im only seventeen with no license. pls no hate, just a super worried friend here !!!
