Upper Abdominal Pain

I have upper abdominal pain (dead center of abdomen just below rib cage) with nausea for past four weeks. The pain and nausea come on about 90 minutes after eating and last for two or three hours. Pain and nausea go away completely if I fast for many hours. The pain is reduced by lying down, especially on the left side with knees pulled up. All symptoms have been getting worse over time. Dr. told me to take Prylosec but all symptoms stayed same even after taking Prylosec as directed for several days. Dr. sent me for CT scan. Liver, gallbladder, pancrease, spleen, and adrenal glands are all normal. Lately, my B.P. is lower than normal, resting pulse is faster than normal. I have unintentionally lost 18 lbs. over past 4 weeks (went from 142 to 124). Recent increase in number of stools per day and stools are bulkier than normal. Blood test revealed high EOS (22), all else normal. Dr. has no more ideas and will not order ultrasound because all appeared normal on CT scan. Any suggestions?

At this point an endoscopy and or colonoscopy would be your best next bet. Talk to a GI about getting these things done.
