I have undergone several tests, MRI of the lumbar spince, chest and abdominal CT scans with and without contrast, colonoscopy, endoscopy to rule out the obvious...
kidney stones, appendicitis, gastro issues,
and my gall bladder was removed 2 years ago. CT scans did reveal several small kidney stones...a few in each kidney. I can't help but think that the issue is kidney related. The pain really feels like it is stemming from my right kidney.
