Suffered from the same during Apr2016.. Had same problem again Mar 2017, Burning micturaction . Lab analysis of urine showed 10-12 pus cells..Treated on norfloxacin 400mg twice daily and alka tone 10 ml with water twice daily for 5 days . Felt mild relief and after 10 days again burning micturaction .. again got urine routine done , shows 2-4 pus cells.. Is it that I am resistant to norflox ..so in doubt got urine culture and AST. Report shows sensitive to almost all drugs and resistant to Amoxyclav, cefaclor, cefuroxime, nalidixic acid, tigecycline... please suggest a suitable course of treatment. my body weight is 116 kg. I am 53 yrs old on drugs for Hypertension and hyperthyroidism.
