Im having same. I was diagnosed Sept 2022 and was on a 12 week course of Budesonid that was entirely successful. I quit taking PPIs and NSAIDs
No issues until end of April when i was having cataract surgery and taking nsaid eye drops every 4 hours for four weeks for each eye. And i began to have diarrhea again. It has been progressively worse - complete with incontinence and nocturnal episodes.
I did get budesonide again but it hasn't worked this time. I am tapering off and will quit this week. I see my GI doc the end of this month and we are going to explore what else it could be. Very depressed about it all.
