[|Human|] When I lay down on my left side I get a pain as if a ballon is blown up my then I get pain and feel sick. When up have a heavy feeling on my side with a little pain. Had scan all is said to be ok it feels like it is around my kidney. I have had kidney stone in past this does not feel like a stone. I get very little sleep as if I turn on my left it wakes me up. Female age 52
[|AI|]  An ultrasound scan is fairly accurate in picking up kidney stones. Even if a stone is not in kidney and has passed down the urine tube which is the ureter, an ultrasound scan can pick up features of such a stone having gone down that passage by means of noting any swelling of the kidney. In combination with an X-ray PUB, we can be certain that to an extent of 90% that there is no stone, but if a CT scan says there is no stone, then you can be sure to the extent of 100%, in which case, the pain in your left side could be due to some other reason. Hope I have been able to reassure you.
