I was wondering if anyone out there with lupus and lupus nephrosis (sp?) had kidney pain. In my research I have found that it is not painful. But, I have been on oxycodone for a week and a half to control my pain while I am waiting on a diagnosis, and a few days ago I developed really bad pain in my left kidney and my doctor found blood in my urine. I know it's not a kidney stone. Could this be related to lupus, if indeed I end up with it? Could it be related to the pain medications? Just wondering if anyone experienced this.

Thanks!
