@dval – Oral budesonide sounds like a good choice now.
My GI story is convoluted! In my 40s I was diagnosed with GERD and gallbladder dysfunction. After gallbladder was out symptoms continued- gravel in bile ducts, causing pancreatitis.
Twelve years ago I developed diarrhea suddenly- autoimmune colitis. Even after treatment I would get bloated, have pain and fatigue. It took years to get a diagnosis, because of different types of biopsy results. I was then treated with immunosuppressant for several months. I’m still fine except for extreme Brain fatigue. I compare it to burn out from the stress of continuous abdominal pain and discomfort.
