@januaryjane- I have a couple of thoughts. With the recent cramps, bloating and diarrhea you could have SIBO Small intestinal bacterial overgrowth. Many of us with IBS experience this. There is certain meds for this - Xifaxan for example. When I get it bad I feel pretty sick. With the facial redness you could have celiac disease- you may have been tested already. Food allergies can give you very similar symptoms. I think this is serious enough to discuss with your doctor. It has a negative impact on your life. Maybe you could have a tele visit?
