I have had 6 years of intermittent bilateral kidney pain without any positive test results. It not only affects my kidneys but also my lower flank area below my kidneys. I recently took a long flight and had both lower extremity swelling and an increase in kidney pain. It is worse when I lay down but it also hurts in every other position. I read on old post from Joseph regarding a Dr Lee Hebert from OSU Columbus, Ohio. Is there still information out there.
