So for 4 years I have seen 4 different urologists and suffered with an unceasing feeling coming from my urethra that I have to urinate. I now have pelvic floor dysfunction. All my urine tests have came back negative and I have probably had around 20. With this said I have a bad smell smell to my urine and particles/bubbles(these don't go away) present that were not there prior to my health condition. I attached a picture. Does anyone have any idea what this is?
