Microscopic colitis

So after getting vac injured and struggling since 2021 with huge debilitating symptoms, and being always dismissed with IBS diagnosis (spent thousands for nothing and thought to kill myself many times because nobody was helping me out), I've been finally diagnosed with Lymphocytic colitis a few weeks ago.

Now I just started again Mesalamine.

Problems is it flares up my symptoms so badly. I'm experiencing constipation again. What should I do?

I also had a glucose SIBO test turned out to be negative but it flared up symptoms as well so badly (two weeks ago).

I'm taking daily: Probiotics Glutammine Tumeric Butyrate Vitamins + electrolytes Digestive enzymes Magnesium in the evening to sleep better Anti spasm med

I'm lactose/gluten/histamine intolerant as well.

Any suggestions?

Thanks!
