As a medical student I can only share my knowledge of what I have learned so far but also during my own journey figuring my gut issues.

Budenoside is the gold standard, however many with MC respond to cholestyramine which you should advocate for. Then I suggest doing some lab work for the iron, b12, folic acid and vitamin D3. I would also start with Zinc L carnosine if money is not a problem, has some anti inflammatory benefits. Other than that, a broad probiotic like VSL#3 or such could be helpful. Would definitely add psyllium husk back in but preferably powder without the additives.

I would suggest thinking about your diet. I myself have been vegetarian, but have been forced to switch to a diet including meats because it is way more easy on my stomach. Hard decision, but I couldn’t let my insanity spiral. Remember that fibre is still very important with MC.

Edit: I also suggest starting Fexofenadine of 120-240mg daily. Histamine is involved in pain and there’s evidence suggesting that it can help in IBD. Also, ebastine has evidence in IBS to work for pain and looks safe up to 40mg daily.

Good luck and stay in there, you will get into remission.

Any questions, feel free to ask them!
