Yeast is a Bacteria. I have
chronic yeast. Been battling it a very long time. It comes and goes with treatment, but was misdiagnosed by the normal tests for years. The over the counter stuff (which are mostly creams inserted in vaginas or used topically for itching) may not do the trick. They don't work at all on me. And BTW, as much as I've had it (more than my share) - no partner ever got it, so make sure you know what you are dealing with. Go to the doc
and IF IT'S YEAST, you'll get on an oral med which will clear it up rather quickly. Antibiotics are not
used for yeast. If he gave her Flucanazole or Diflucan - than that IS for yeast. I would make sure and ask exactly what she has so you know what you need to do for you.
I know women tell other women to take acidophilus and eat yogurt - I have done all that in mass quantities over the years - it doesn't truly help. It doesn't. Because of my weird immune system so hyper sensitive to this bacteria, I see the leading gynological surgeon at the UW who specializes nationally in yeast (great job huh?!) and he unequivocally states it helps with stomach flora - which comes out in your stool
. Doesn't help prevent or cure anything else!
Good Luck - I know how severely irritating, itchy, and uncomfortable it is!
