Can Benign Tumor In Pancreas Cause Severe Abdominal Pain?

I m desperate. Have had terrible stomach pains (burning, pain, etc. and Gerd for almost a year). Have had CT, Gallbladder workup, upper and lower scope, and other tests. Nexium, Protonix, etc. only make it worse. Doctors in Scottsbluff NE, Rapid City, and Denver seem to find no definitive answers. I have benign tumor in my pancreas, one on my lung, and had a couple of small intestinal polyps removed. I have even tried acupuncture. Can t isolate what foods (chance all the time), have elevated bed, etc. but nothing is helping. What are we missing???
