I Haven't Felt Well For Some Time. Symptoms Are Mild

I haven't felt well for some time. Symptoms are mild diarrhea but more of a soft stool bowel movement, pain that was toward left side but now around and above belly button. Blood work and most stool tests came back normal. Still testing stool culture but I am experiencing discomfort in stomach and still loose stool for several days. Havetaken Imodium. Feel like I have rotten stomach. Have been on mostly liquid diet. Had history of diverticulitis several years ag but dr doesn't think that's it because. Am not fevered.
