Hello I m suspect that I Have a hernia. Have been experiencing dull, and pulling type pain around my belly button. It has always been a in E not its a out e . Just recently I had a cough, at night my hand was over belly button and coughing caused belly button to pop up and bounce my hand up! Have also had unexplainable diarrehea for a few years. My mom,older brother, sister and a niece and nephew have had them. Realize after cough, its probably what it is, but can that cause diarrhea?
