@so1frustrated Well, dang! I know you were hoping for an end to this! The last time I had a kidney infection, I was given a course of antibiotics, but it wasn't a long enough stint. My PC [first time it was a substitute dr] put me through a second course for 14 days. I don't recall which antibiotic was given, except that I had to get on probiotics to straighten out my gut, when everything was killed off.
With your continuing issue, you may have to advocate to get in as soon as possible. Let me know what happens, please.
