ok so i have this big soft red bump inside my belly button. its pretty big but u can only see it if i open up my belly button. i noticed last night that there was a LOT of dried puss in my belly button and when i took it all out i noticed the bump inside. the puss smells really bad and i dont know what this bump could be. someone said a hernia, but its not sticking out of my belly button, someone said a boil but it doesnt look like a boil at all. it's long and I can't seem to find the end of it. it just keeps going. i don't know what it could possibly be. there was a tiny bit of blood but not much, and i've been having random pains above my belly button, in my lower back and my sides. does anyone possibly know what this is??
