Last Friday I woke up with gas pains. Needless to say, it smelled like rotten eggs when passed. Woke up again later that morning, and had bad diarrhea. Went 3 times, then the diarrhea went away. Haven't had diarrhea since then, but I'm still left with a few symptoms. 1.) a hungry feeling (feels like its gunna growl but never does) Doesn't always go away after I eat but most of the time it does.... 2.) Normal stools but I feel like I have the urge to go. 3.) Gassy and burping more than usual. 4.) Occasional nausea along with the emptiness. My mom has IBS and so does her sister. Could it be that? Food poisoning? A virus? I have had no fever, or blood in my stools either.
