I have been having severe abdominal discomfort, spasms and discomfort upper mid back following a meal, nausea and occasional wretching even after the stomach is empty. I think exercise may be making it worse. I had a renal ct done to rule out renal artery stenosis. It showed stenosis at the origin of the celiac artery with poststenotic dilatation, this stenosis was thought to be related to the diaphragmatic cura. the mesenteric arteries were patent. this was found in Nov 2013, but I now have had an ultrasound of abdomen that was normal. please help me find a solution to this problem,
