I have rbc of 20-30, blood +1, white count normal..am overseas, pee 3 times a day(normal for me), but worried that I might have uti..had blood in my urine 4 mths.ago too with alot of pain..had a keflex antibiotic handy, so I took that, w/o seeing a Dr., (no $ for tests..) how long does uti last, and I thought I flushed well then..but now, in Thailand, and going to even hotter, Cambodia..hesitant to get Ultrasound, as sometimes they don t show stones..which I think I had in past, (10 yrs ago), do not want uti to turn to kidneys, no flank pain...just some feelings of dryness/evacuated bladder...I am normal weight, 62 yr. female
