A few weeks ago I had red urine. a couple days later it was pinkish. Then, a couple days after that, it was cola-colored. I went to see a Urologist, but he couldn t see me so i went to my Cardiologist. he presecribed antibiotics for 10 days. As soon as I started on them, my urine became clear again. Now, 3 weeks later, I just had cola urine again. I m schedulaed to see a Urologist in 2 weeks. Any advise? I m 59 and never had any issuses with my urine.
