Nephrology/Renal Cyst and Back pain


proofer wrote at 2010-04-19 11:17:05
I hate to see someone who has not had a painful renal cyst declare that they are always painless. The enlarging cyst presses on nearby structures and, when large enough, causes pain. Ask me, I live it. Granted, the cyst itself does not hurt, but BECAUSE of the cyst patients have pain.  I am one of them and I've dealt with it for over ten years.  I have seen several urologists and nephrologists, and in the beginning they tried to tell me that my flank pain was not caused by the cyst.  The more it grew the more pain I had. Those doctors are now acknowledging that cyst can cause pain. It was drained (percutaneous aspiration)and I was pain free until it regrew to it's former size, which they often do.  Don't believe people when they say simple cysts never cause pain, like the above writer. The world is not flat either. They can cause pain and they do cause pain. And by the way Newell, it is pus, not puss.

My husband has the same exact problem. He has a kidney cyst and

the urologist keeps giving him pain pills which do not help.

He has severe pain in his lower back and lower abdominal and nothing helps the pain. What ever happened with your dx.???

I am sorry Dr.that your answer is incorrect. I have polycystic kidney disease and have suffered low back pain for years. Recently, woke up with such severe back pain that I could not move. My nephrologist confirmed due to the disease, my kidneys had grown quite large and are now pressing on my low back muscles. This is causing the muscles to work around the issue and in turn, pull on my spine so it was out of alignment. Chripractic care did help but will not help in the long term. Please check "Polycystic Kidney disease" for more information.
