Actually, treating as a yeast infection, when there isn't a yeast infection, can cause harm. Not too serious, but it's not good to take something, your body, doesn't need.

I had a yeast infection, years ago, had bronchitis, in college, the anti biotic, is what brought about the yeast infection. It's dry, itchy and white.

Could, always, get a check up, if things seem abnormal.
