My husband is experiencing moderately severe pain in his lower back on the right. It does not feel like "back" pain, nor does it begin or end like typical back pain. The pain comes on unexpectedly and increases in intensity to the point where he becomes nauseous. It can take several hours before the pain gets so severe that all he can do is lay down. The thing that has us most perplexed is that when he lays down, the pain begins to subside within a half hour or so and is completely gone within an hour or two. The frequency of these "attacks" has increased (from 1 every couple of months to 2 or 3 times a week now). He has gone to his doctor twice now. He has ruled out kidney stones/kidney infection and he has had an xray done on his back. But his doctor says his symptoms don't really match up with anything so it will be a process of elimination.

Are you aware of anything that could present itself in this manner, yet go away after laying down as described?

Thanks,
linda
