Pain in left ribcage worse when moving or with pressure.pain at base of spine.loose stool 5 days.slight nausea. very worried?

Diarrhea: If the discomfort and tenderness are just below the left rib cage and with loose stools,this suggests inflammation in the descending colon such as seen in viral infection, inflammatory bowel disease and,less likely, diverticulitis. A viral gastroenteritis is most likely and resolves in a few days without specific treatment except rest, avoidance of harsh roughage, good fluid intake. See your MD if
