For the past one month, I have been suffering from burning urine sensation. I consulted with a urologist and he prescribed me antibiotics. It didn't work. I went to do the Urine Culture and Urine routine. It came back normal. I continued the antibiotic but it didn't work. I did my Ultrasound and it shows the bladder wall appears thickned. I did my URINFLOMETRY and it is normal. Recently, I have been prescribed with Mirabregon and Founten D. There is a slight reduction in the burning sensation. But I feel the urge to go to the bathroom frequently. What might be the possible reason for it? Should I go for Cytoscopy? Thanks in advance
