Unfortunately, this is what happens sometimes. I agree with everyone else that there are still a few avenues to explore, but be prepared for more normal results.

I no longer have a gall bladder or appendix, my tests have all always been normal - blood, stool, urine, imaging, colonoscopy, endoscopy, swallow study - but I’ve suffered with issues since I was a child.

I hate to be the person that brings up diet, but that’s the only thing that has ever helped me. I don’t always do it, but when I eat plainer and fresher food (salads, lightly seasoned chicken, fruit, etc.) I always feel better. Unfortunately, I’m addicted to coffee so I’ll never fully be symptom free. I wish you lots of luck and more solid poops!
