So this could be way off base, but in August I was finally diagnosed for MOGAD. It is a very rare autoimmune disorder and though it only became more severe in Feb. 23, I am beginning to understand symptoms from two years ago. Yep, possible UTI's 3+ that had all of your symptoms, yet no bacteria in conclusive lab tests. MOGAD effects the bladder and bowels, and can be a precursor to this disease. I only ever went to Urgent Care, my doc too busy to see me quickly. Every time, it's a UTI! NOPE! So I suppose if I had known, I could have started investigating sooner. There are some clinical trials out there with these same symptoms, I am not sure of the criteria. But one thing I simply know now because of my experience, is don't give up, be your own self advocate!
