kidney stone pain location

  On Christmas Day of this year I experienced severe pain in my
  lower abdomen.  A urine test showed no blood.  The pain subsided
  a day later.  Today, I once again suffered severe pain, only
  this time under my right rib cage in the front of my stomach.  
  (Not in my back as is the common symptom.)  My question is, could
  these pains be coming from a kidney stone.  If so, what should
  I do?  Thank you...Mike
