Thank you for your query at DoctorSpring.com
Your pain may not be related to the kidneys. Contrary to the common belief, kidney problem doesn't manifest as pain in the lower back. Even if it causes , it's one of the rarest manifestations.
Most of the times a stone or done thing to do with kidneys discovered accidentally when ultrasound is done for abdominal pain . You don't need to worry .
We can wait for the CT reports to be available and then take a decision. Ct is better than ultrasound to search for nephrotic syndrome or analgesic nephropathy. Ultrasound can also give an idea, however CT is preferred.
And if the kidney is damaged it will show in the ultrasound. If your urea and creatinine are fine, then again there is nothing to worry about.
Feel free to discuss further,

Thanks for your answer, it's much appreciated!
I would just also like to know whether the blood and urine tests I had would have confirmed no problems with creatinine and urea, as you mention? I was under the impression it was just blood and protein that the doctor was trying to detect.. or are those just jargon words for the same thing?
Also, is nephrotic syndrome / analgesic nephropathy likely to go away with discontinuation of the medicines?
Once again thanks :)
As you mentioned all the urine and blood tests are supposed to be normal, we can presume that most of the functions are normal . However structural change in the kidney can be assessed only with ultrasound scan or ct scan. You are at risk of kidney problem as you have been taking lot of pain killers but it won't manifest suddenly or so soon. You try to avoid now itself as any subtle change won't be seen at this stage. Nephrotic syndrome or analgesic nephropathy won't reverse as soon as you stop the culprit as it would be like removing the knife after stabbing. The stab injury will lead to complications and it won't get reversed if you take out the knife from the wound.
Hope this was helpful,
