I0 yr old sister has flank pain on her right side..It's an achy pain, and it's irritating her. It goes on and off, and she's had it for about 5 days. She had her left kidney removed due to a disesase when she was small so we are concerned. What could it be?
Don't say things like "go to the doctor" or "she will die" or "Go to the ER."
