When I breathe I get pain on the right side of my back. Its in the middle to the upper sections. I got x-rays a few weeks ago and they came back negative.
That type of a pain could be caused by a nuraber of different things. I would go back to the doctor and ask what else it could be. Maybe it's muscular, which wouldn't show up on an x-ray. Or maybe you need a test other than the traditional x-ray, like a CT. Be polite but persistent.
