Hi, I have been experiencing intermittent severe upper abdominal pain for approx 19 mos, always associated with eating. During the attacks, I have experienced at times R shoulder pain, nausea, no vomiting & always abdominal distention during & immediately after the attack. I have been to a GI specialist & have had normal abdominal CT, abominal u/s x2, upper & lower endoscopy & normal pancreatic & liver enzymes. I have a very large hiatal hernia, GERD, H/O breast cancer, age 63yr. I have ben prescribed donnatol, which helps some. The pain attacks last anywhere from a few minutes to as long as 2 hrs. The frequency has recently increased from 1 -2 attacks per month to 2 -3 per week. Fatty meals can exacerbate the attacks, but have had attacks eating soup & salad.
