Hello all. Its now been more than a year that I keep having foamy urine. I have tested and it doesn't seem to show any protein in it. Did extensive urine analysis, full blood work, and a abdominal sonogram, and an MRI. Kidneys seem to be fine on all those tests. There is no pain. How ever I have started to notice the foam after one day when I held my pee for too long and then went and I did have slight kidney pain that one time. And I think ever since then I see heavy foam. But again its negative for protein. I have tried everything, i stay hydrated, its not a chemically induced toilet water, although in some toilets the foam disappears almost instantly. In my toilet the foam stays and visible for a long time. I was wondering if anyone has encountered this before?
