I've been fighting what seems to be a UTI for about 3 weeks. I was on Doxycycline for 2 weeks. Some of the symptoms (frequency, aching pain in genitals) cleared up but they gave way to new symptoms (raw, sores, itching). Never any burning on urination. I just had my 3rd office visit with urine test and it is still showing white cells. I requested a vaginal exam because now the symptoms seem like a yeast infection, which my dr. also thought. But inside I was just fine. He said he doesn't know where the yeast is coming from. My question is this: Can Candida be in the urinary tract and would it result in an elevated white count? A urine culture was done on the first visit and I was told it "came out negative". I neglected to ask "negative for what?" Would they even have been looking for Candida? At any rate, I'm now taking Diflucan. . . next appt. in 2 weeks. This all started when I started pounding down water, when I hardly ever drank it, for several days. My own personal theory is that Candida was lurking in my kidneys (and probably other places) and got flushed out, causing problems on the way. Does this make sense to anyone?
