So this is super embarrassing but I have a slump just inside the opening of my anus. It feels swollen and tender. It hurts like hell whenever I stand up ,sit on it, walk or put any sort of pressure on it. It's so annoying because it's hirtong a lot and I'm on holidays and miserable Since I'm away I can't get painkillers and I don't want to go to my gp because I don't want to tell my dad (I'm a girl and I live with him)
