Your belly button is a point on your belly wall where the scar of where once your umbilical chord was located. The area around it is like the rest of your belly, made up of skin, subcutaneous fat, your abdominal muscles, a bit more fat, and inner lining and then you have your abdominal cavity where your guts (viscera) are.
The most common symptom is a dull abdominal pain near the belly button that radiates or changes near the right lower belly. There are other symptoms that aren't so common. If you find yourself checking off several of them, it might be time to contact your doctor or go to the hospital.
