Well, after a few years of bleeding, & other UT problems, including elevated proteins which mysteriously came & went for that period, someone finally cut me open . For 3-4 years thought it was cancer (inituial dx in 1979) versus Hypochondria!
Anyway, finally had a Uro that had a hunch! Cauterized the offending blood vessels. But not a total cure.
As for 2004, the weirdness ( gray, cloudy urine) went away with my remission. I was afraid it was the F word for awhile!
Now, I just worry about my friendly Kidneystones. ARRGGGH! This DD really sucks. But you already knew that.
Yep, could be many things. I hope its something minor for you!
