I have been having severe lower back pain off and on now with severe tenderness. I also have pain thats more "sharp"; like something is sticking me, in both of my buttocks. At this point, I am not able to sleep on my back longer than 5 mins, and when I sit or stand for long periods, that makes it worse. My doctor recommended therapy, which I completed with no relief. I had an MRI of the lower back, and it came back normal. All xrays were normal also. No one seems to know what the problem is; the pain is so severe at times, I have to walk in a slight "bent" position. I have to work, and I don't know what to do. Can someone recommend anything??
