Hi Sir, I saw some worm like clots this morning in my urine , they were dark brown color. I have been experiencing some fever sine last 4 or 5 days (up to 100.2 F, I would only take brufin and fever would disappear just in a couple of hours) . 5 days ago my urine was dark yellow. I started drink more water and the urine color was normalized. But I experienced very little burning while passing the urine. But when i started to drink more water that burning went away. But today I saw these clots and they were like 8 to 10 and visible with naked eye. I am 40 years old male. I smoked for more than 15 years and quit smoking almost 4 years ago. I ll appreciate if you help me figuring out the problem.
