I'm wondering, would the ice cause her to have to much moisture in that area thus causing a yeast infection? I always thought when women had a yeast infection, they would know it! By that I mean, intense itching, pain, etc.. (Knock on wood), I don't really get those so maybe I am way off here. You mentioned bacteria on the ice cube, if that were so, if she ingested it by itself or in a drink would that have given her a yeast infection in the mouth? I know that she uses those bags of ice that you buy in the stores if that make any difference. I guess poeple can get bacteria on their ice through their own ice machines at home. Gees, I never thought about that until now.
