I have had stomach problems since I was 5 or 6, in hospital twice. Anytime I would get least bit nervous, like dancing lessons next day, would be up all night vomiting and diarrhea, all night long. DX as spastic colon back then. Had problems all my life. Dr's call it IBS now. Not sure when MS started, so not sure it had anything to do with it. Is IBS autoimmune? Had Hishimoto thyroiditis, when had tumor on thyroid, in 2005, another autoimmune? Not sure ...
