What can i do to determine why i have persistent kideny pain?

Not a ER problem: This is not an emergency room job . You need to see a urologist as an outpatient for proper evalauation. The job of the emergency room is to evalaute and treat acute events and decide if a person needs admittance to the hospital or to go home with proper follow up.

Not for the ER: The er can do some things, and some things rapidly. However to understand why you are getting recurrent kidney infections, there are tests that can't be done in the er. These questions are best answered in conjunction with an evaluation by a urologist. They are able to do different tests not readily available in an er. Good luck finding the answer.
