Have had cipro (ciprofloxacin) amoxicillin and rosphen for kidney infection caused bt strep baceria and still have it what should be next step? Iv antibiotics? Help

Is infection still? First need redo urine culture to make sure if it is still same infection or another kind! strep is sensitive to treatment unless it is enterococcus! if it is strep and came back then it is more of re infection than failed therapy. Also, need ultrasound to make sure no structural reason like a stone disease exists which would cause recurrence.
Consult. An infectious disease specialist. Make sure you don't have kidney stones.
