I have upper left quadrant pain under ribs which often radiates to back. I have diahhrea which floats with what looks like oily spots and alternates with constipation. I've had 3 ct scans (1 with constrast), mri, two endoscopies, one colonscopy, upper gi with barium, lower abdominal ultrasound, fat fecal, fat stool checks, enzymes tested every couple of months, blood work for aids, arthritis, diabetes, thryoid, ms, cf, myasthenia gravis, you name it. I had gallbladder out in 99. Daily moderate to mild pain punctuated with occasionally 15 scale pain. Can't eat greasy, fried, carbonated. Have lost 45 pounds. Non-smoker, never drank. Two gastros have diagnosed severe ibs and put me on celexa 10 mg a nite, and levsin for pain. They are adamant I don't have pancreatitus but I'm still concerned. If I had it wouldn't it have shown up on these tests? Am very concerned they are missing something.
