question: I have been having moderate to severe kidney pain for the last couple of weeks.  I recently discovered a bruise on my skin above the area where my kidney is.  I've also been nauseous and very fatigued.  I was in the emergency room for what turned out to be ovarian cysts, but the blood tests did show an elevated bun/cr ratio of 23 and a glom filt rate (gfr) of 94.  I am a 37 year old female with no real health issues besides endometriosis.  Should I be concerned about the kidney pain?
