I've been experiecning left flank pain for awhile now, since I went on a cruise and rode a jetski. My kidneys are okay (according to a CT scan), but it feels tingly in my upper left back ribcage area, and the is pain getting worse. Despite the CT scan, it still feels like it could be kidney-related. It seems to worsen with driving and when my bladder is full. I have kept a pain journal but the docs are not interested in that. I've only taken Motrin and Tylenol, but as the pain gets worse I'm getting worried its something really serious. Any ideas?
Why not a muscle problem or nerve problem in your back caused by the motion of the jet skiing? That certainly makes sense with the driving issue, since when you do that you're putting your back and pelvic area in an ususual position. Have you tried stretching exercises for the back? Have x-rays been taken? Have you tried cooling/heating treatments on your back? I wonder if you tweaked a muscle or a disc in that area?
I hope you find an answer from your doctor or from a second opinion soon. Here are some links that you might find useful in the meantime:
