Male, 21. I'm Having Burning Sensation From The Past 7 Months. I've Had Many Tests 4 Times, Like Urine Culture, STDs, Ultrasound And Many More. And every time, Everything Comes Normal. There's No Bacteria In My Urine. I've Tried Every Medicine Which Was Prescribed By The Doctors, Which Include:- Moxiflox - Norflox - Urispas - Zenflox UTI. Even After Trying All Those Medicines, The Burning Persist When I Pee. I Went To Another Doctor And Prescribed Me These 3 Medicines:- Renalka Syrup (2 times a day)- Nitrobact 100 (2 capsules a day)- Urispas (2 times a day) I've Just Given Up :(Every Single Test Comes Normal, No Signs Of Any Infection, No Signs Of Any Kidney Stones Etc. What Could Be The Cause? And Is The Medications Which I'm Currently Consuming Is Okay To Take? Because I Can't Keep Up On Medicines As It Tend To Harm The Organs If Taken For A Long Time.
