Boil/cyst?

Lady

I have a really large bump on the upper most part of my vagina (mons pubis if you wanna be technical) it’s painful and just feels really solid and large to me. I’ve had boils before and I thought this was the same but it won’t go away and hasn’t even decreased in size. It’s been about 3 days. I do have pubic hair. I shave sometimes so it’s possibly an ingrown hair? It just seems too large to me to be that but I’ve been working myself up about it & am just freaked out now. Thoughts?
