Hi...I had my first IBS attack 4-years ago...ended up in the er on a morphine drip. They took out my gallbladder thinking that was the problem..guess what....wrong! I lost a part of my body that had nothing wrong with it. I had my second and third attacks within the last 2-years...same pain...er on a morphine drip...The GI doc said I was a mystery to him as the scopes came up clean....no diagnosis....I am goin back one last time as my stomach bloating is more frequent now...I believe it will be IBS...oh , I did find a drug that does work...vicoprofen....yes its a narcotic but it also has ibruprofen in it...it is not like regular vicodin which does nothing but cause me a headache.....this new combination is the best thing I have ever tried....takes away the pain and cramps and also helps reduce the diahrea by causing some constipation....I am 49 and will not live in pain the rest of my life....I will keep you posted as to my condition....if it is IBS which I am certain it is...then this is the drug for me....no more suffering...
