Talk to Urologist on Urine Problem

I'm experiencing a strange issue with my urine. In the morning, my urine is very dark, and initially, it's milky, but then it clears up. There's also pus in my urine. One day, I touched the milky urine, and my finger had a white, creamy texture. I urinate frequently in normal amount. And every time, I see bubbles in my urine. The bubbles form at the top of the stream and disappear within 15-20 seconds after entering the toilet. Occasionally, I feel a sharp pain in my bladder and pelvic floor for 6-7 seconds.

I've had CT scans, urine cultures, RFT, and HbA1c tests, and all reports are normal. I've taken levofloxacin, ciprofloxacin, and diflucan tablets, but there's no improvement. Please help me; I'm very distressed. What should I do?
