@neciern - hi, and welcome to Mayo Clinic Connect. I've moved your post here, to an existing discussion on the same condition, so you can chat with others:

- How to manage microscopic (lymphocytic) colitis? https://connect.mayoclinic.org/discussion/microscopic-lymphocytic-colitis/

Hoping members here such as @pichulita @barb1954 @cows1806 @donnagail and many others will join in and comment on whether your experience getting diagnosed with lymphocitic colitis, yet no changes in diarrhea on medication, plus now onset of significant abdominal pain, cramping, nighttime symptoms and severe right lower quadrant pain, etc., all seem typical or atypical. They may have thoughts on what else should be done to ensure you have the correct diagnosis.

neciern - what symptom or symptoms are bothering you the most lately?
