All Day I Have Had Discomfort And Cramping With My

all day I have had discomfort and cramping with my intestinal tract necessitating numerous trips to the bathroom. I had a normal BM this a.m. followed by diarrhea, the color of raspberries. I ate several blueberry muffins loaded w/blueberries, and wondered if my condition was causes from over-ingesting this fruit. I have not had a reaction from them before. Thank you
