It's right on my fanjo (labia Majora) I'm assuming it's an ingrown hair that's got infected but can't get it out. I've tried plucking a few hairs out (they all had pus at the bottom, grim) but that didn't work. There's no head on the huge sore lump that's formed, hot compresses aren't working and it's getting sorer as the day goes on as it's rubbing on my underwear. What else can I do?
