Back in the last week of July I got a bit sick, nothing debilitating. But at that time I did develop some very dark urine. After I was feeling better, the urine looked better. Then my urine fluctuated between dark and normal. It seems to be normal in color in the morning and evening but gets dark during the day when I'm active. It can be dark amber to almost coffee colored, red at times and it's very cloudy and sinks to the bottom of the toilet.
I did go to the doctor, had an IVP done, blood work, ultrasound, some other tests on my urine. No sign of stones or infection. I also have no pain or fever. Except for the blood, tests come back normal (a previous test a few years ago showed cysts on my left kidney and on my spleen, apparently not a concern).
I do drink at least 8 cups of water a day (no coffee or sodas), very diligent with this since the strange urine appeared. Yet all the tests show nothing. It's been 10 weeks now and I'm discouraged. Is it possible to have blood, very obvious at times, and have no problems at all? Will it eventually go away?
If lab tests did not reveal a cause for the hematuria, then a cystoscopy may be needed to diagnose. It could be due to bladder tumors or stones.
Hope this helped and do keep us posted.
