Because I had searched for 18 years answers to my digestive, epigastric pain, weight, loss, food problems, and many more issues. I thought I would mention here about vascular compressions.. It’s not something doctors would look for, but it’s worth a try if you done everything else. I had Mesenteric artery ligament syndrome, which the mesenteric artery ligament is squeezing the aorta when you eat. It causes, severe pain when eating, and eventually all the time. I had every G.I. test several times over and finally found on this site the information about it. You can look up MALS which helped to lead me to a resolution from my Mals. There are several vascular compressions that cause digestive issues and pain. It’s worth a try.
