What about ingrown hairs underneath the skin on a vagina? Those hurt. I once had a big one, thought it was a wart, freaked out and after trying to squeeze it for days... some pus came out but you could just tell that there was more. So I again started squeezing it and it was pimple like pus that came out but I could still feel there was something underneath that... IT WAS A BIG pus ball... you could see the white, I freaked out thinking that it was bone or that my vein was underneath that... but still couldn't resist the urge to free it.... it hurt like a mother fucker and when I finally freed it, it was the size of the cotton on a Q-Tip. It was all hard pus, it wouldn't even pop when I squeezed it between my fingers, there was a hair in it. So I'm guessing it was an ingrown hair underneath my skin???
