I'm very sorry for thes loss of your daughter. No parent should feel that kind of pain.
Idk about the fluconazole from mexico but I had some luck just asking my doctor to phone it in due to yeast infection symptoms. I told her that I've had one before and the symptoms were all the same. No questions asked. It was only 2 does but it helped. Also, I've read that fenben has antifungal properties as well as antiparasitic. It might be worth a try.
