What causes the bone sticks out from under the stomach?
Patient: Hi, I m a 15 year old male. There s a bone that sticks out from just under my stomach, and it s been there for as long as I remember. It sticks out a lot when I m in the deep end of a swimming pool or when I m doing sit ups. Is there a way to stop this? Doctor: Hello.  This sounds like an umbilical hernia and you need to have a doctor look at it since it may need surgical repair
