I was diagnosed with IBS 6 years ago after undergoing a colonoscopy and drinking barium to X-ray my GI area. Nothing showed up with these tests and so that is why they diagnosed me with it. The only symptom of IBS I have is intense cramps in the area. Can that alone be IBS because everywhere else I've read mentions relief found from diaherra and/or constipation, which I have neither. I would appreciate some input on this.
