I have suffered some form of IBS or another since I was a child. During my adult life,for the last 15 years, these symptoms have been disabeling. When I have an attack it causes severe lower abdominal pain which quickly turns to severe nausea and vomitting. The symptoms last from 12 to 24 hours during which all I can do is lay in bed and vomit. I have been to several GI's and had every test, they can find nothing so they tag me with IBS. Does anyone else suffer these kind of symptoms? What do you do to help or keep the frequency of attacks to a minimum?
