Hi my name is lidia and my mom has a big bump on her belly button area. They say its called a kilo . It hurts her very bad she is 49 years old and she has arthirtis as well. No doctor ever says what it is or what i can be. We go yo kaiser permanente and they are the best right? well apparently not cause they cant even see what the hell is the bumps she has. I google kilo and nothing pops up about it please help.
