I’m curious if an extended (1-2 weeks) fast could help. If eating is what bothers it maybe an extended break could help? Fasting seems to help a variety of other medical conditions.
Yes, there is recent evidence regarding this with pancreatitis too. I fast whenever I sense my pancreas is inflamed (as is also customary in hospital visits - practically the only treatment). However I'm bordering (sometimes crossing) underweight so I don't do it regularly.
