I’m an active 42 year old male who has been dealing with IBS-D since high school. About 6 years ago I was diagnosed with GERD and now take medication for that. I have never experienced this left side, abdominal & lower back pain like this until about 2 years ago. The pain comes and goes, but can be pretty severe at times. I have had both a colonoscopy and endoscopy that came back OK. I have had a kidney stone before, so they did an abdominal CT. It showed a few stones, but none causing any blockages that would be causing this pain. I have had blood work done and all came back OK. I have been pushing for an MRI but the doctors seem very reluctant to say the least and just blame it on IBS. My father passed away about 4 years ago from Kidney cancer. He had several CT scans that came back clean, it was not until he had an MRI that they found the cancer. By this time it was too late. My lower back, left side and lower abdominal area is killing me…. Could this really just be IBS and do I have the right to push for an MRI?
