My doctor diagnosed it by looking under the microscope, and prescribed
Diflucan, which only made the symptoms about 10 times WORSE. I then tried Monistat, which helped minimally. Last time I went back, my doctor again saw yeast under the microscope, but also did a culture, which came back completely NEGATIVE for everything -- any species of yeast, bacteria, Chlamydia, Gonorrhea. I am now entirely confused.
