Hi, not sure how to use forum, I wrote heather over ten years ago, when she was still in New York, I think, and she told me at the time that if you have certain symptoms it probably wasn't just IBS. I am seriously at the end of whatever rope I had left, and I just wanted to know what you guys do with severe colitis , diarrhea predominant. Are there doctors who treat mystery cases? Ugh, am so stunned by latest doctor, I can't breathe. Thanks for any input, and peace and healing to you all.
