I'm in the same boat. Haven't been diagnosed with IBS exactly until they can rule out some pancreatic disease and a few other things. Cat scan was pretty inconclusive. Was put on some meds for spastic colon which only works sometimes. Really wish they had a way to test for it. Nothing worse then not having a true diagnosis. Not happy with my gastro guy. Never called back with scan results, never gave me anything for my pain. I had to call his office to get answers. Was then told he wants to see me in a month. Really? For what? I've already had tests up the wazoo with no clear answers. This may be the last time I go see him. May be time to get a second opinion.
