Welcome back, we are always here. Sorry about your pain. Has anybody suggested a MRI of your G.I. and other surrounding organs? If your surgeon is still around you might try calling him/her and they could direct your local doctors for various tests. My doctor always asked for a diet diary of at least a week, along with output consistency and frequency. I really don’t have any suggestions that are based on evidence/experience. Try searching this site for similar symptoms. Report back please so others with the situation can think it through with their doctors. Good luck
