@amm97 - Did the tests show which abdominal arteries were narrowed?
I have had a variety of abdominal pain causes- still have some.
One of the most painful causes was narrowing of the celiac artery due to a ligament from the diaphragm indenting the artery- this is what is called MALS. Median Arcuate Ligament Syndrome. The pain gets worse when one is digesting a meal- less blood flow to the intestine. I had pain also when sitting bent over. Most people show weight loss. Not me- I gain weight with everything!
I have had severe pain from esophagitis, gallbladder, bile ducts, pancreatitis and intestinal inflammation.
If I were you, I would see a gastroenterologist at a major university medical center and have your tests reviewed.
The narrowing of the abdominal arteries should be re- evaluated.
