I am an RN. Known history of renal calculi. left flank pain, radiating to my abdomen. tolerable pain. urinating okay, don t appear to have hematuria, urine is clear and yellow. pain has been constant for about a week now. no fever, chills, sweats, no nausea or vomiting. I have increased my water intake. should I just wait out the pain, keep hydrated and hope the stone passes, or should I go to the E.R.?
