Pain in kidneys, back

  I have been experiencing pain in my back for a number of weeks.  
  It seems to be mainly localized in my right kidney region.  
  I also experience mild nausea that comes and goes throughout the
  day.  No problems with urination or unusual bleeding, etc.  
  The pain seems related to movement - for example, if I lift
  both arms over my head I can feel the painful spot.  The left
  kidney region also is painful from time to time but not as bad
  as the right.  I'm wondering what could be causing the pain,
  whether it's kidney related or not.  Could it be kidney
  stone(s)?  Would I feel a kidney stone with movement or would
  the pain be constant?  What other kidney diseases would cause
  back pain?  Or is this kidney-related at all?  Thanks!

Dear Jim,  
The pain, which you are describing, could be due to several reasons including muscular, renal or intraabdominal pathologies.  Renal pain usually is unrelated to movement.  They classically are colicky in nature and are associated with sweating and vomiting.
Therefore it is not easy to pinpoint a cause for your pain over the Internet.  However a planned approach would be as follows:  
Consult your doctor
Have him examine you
Get a urine test done to see if there is any evidence of microscopic bleeding (hematuria) in the urine or  infection
If the pain persists and the above mentioned tests are normal- you need evaluation of your back, a plain x-ray and an abdominal ultrasound.
