I have been taking it for stomach pain for one week, and it hasn't helped much. I have intermittant attacks of upper abdominal pain. I can go for months with nothing and the have an attack that lasts for weeks. I've had a cat scan and colonoscopy and endoscopy and was found to have an inflamation about a year ago. DOes this med. work for stomach pain that is not due to gerd or acid reflux.
