Suggest Remedy For Abdominal Cramps And Diarrhea

I have had stomach cramps, liquid bowel movements for the past three days. Today, no bowel movements just the urge to go yet only gas exits the bowel. Have taken Imodium as directed as well as alka seltzer to settle stomach. Have eaten only toast and soup. During this three day span, I have had runny nose and chest cough. Thoughts?
