So sorry you’re going through all of this! Wow. I have had a few similar issues. Mostly with pain in chest fit over a year and swallowing. Losing weight. A lot of same tests as you. But I also had cta w contrast of my stomach and special ultrasound from a vascular surgeon. Was diagnosed with MALS! So grateful to have a diagnosis. Are they doing any surgeries for you? Procedures? To enable to to eat more food etc? Wishing you good health! And hang in there. There’s so many drs out there to help you. 😊
