I've been very concerned about my urine lately. I've been noticing a lot of white clumps in my urine that just sit at the bottom of the toilet. It sometimes comes out in big clumps or just tiny particles that float around the water. I've taken them out of the water and they seem to attract to each other, they are very gooey. I had a UT but I got treated for it and my last urine test came out clear. I do not have a yeast infection neither and I KNOW for a fact this is not discharge. I've also been having very painful lower back pain right where my kidney is placed. Also my pee is cloudy. What can possibly be wrong with me?
