Why would someone have cloudy urine off and on? Like, once a day. Yesterday I had it in the morning first thing, today midday. It's been happening within the past few weeks off and on. I saw my doctor on Tuesday and he did a urine test but it was clear, no cloudiness, and he said everything was normal on it. He felt my abdomen and back and said he didn't feel any enlargement or swelling. I had kidney/liver function blood test came up normal, and tomorrow I have an abdominal ultrasound in the morning and I'm pretty scared they're going to find kidney cancer or something. Looking for reassurance. I'm well hydrated too.
