Bump/boil/ingrown hair

SOS

I have a bump on the inside of my thigh near my vagina (where the side of ur underwear sits) and i do not know how to treat it. I don't know if it is a boil, or an ingrown hair or what. It has been here for a long period of time but this is the worst it has been because i have been popping it. It has been draining but i don't think it is getting better. and it HURTS. I got it when i was on my period a few months ago and i was on my period last week and it made it worse. I havent told my mom because i am trying to avoid going to the doctor because i'm so embarrassed ): has this happened to anyone else? what should i do ??? Plz lmk
