yeast infection

cynthia

so I had a yeast infection and they gave me metronidazole for seven days and one pill of Fluconazole to take my 8th day. so i took it yesterday morning and my cottage discharge came back along with burning and itching again! I thought it was supposed to work instantly? Why did it make it worse because my discharge had started going back to normal before I took this pill. is it supposed to get everything out? Or should I go back to the doctor?
