I'm 22 year old female (unmarried). I had been to the op on 20th of april due to uti symptoms with fever, vomiting and increased urine frequency. I was prescribed ciprofloxacin for 3 days which didn't subside my symptoms. I had to later take another course of nitrofurantoin, oflox and levoflox. It's been a month and I still have flank pain, back ache increased luts. My urine culture report, as of today has shown resistance to levoflox. Can you please help me by letting me know why exactly isn't my uti going away?
