Yeast infections of the vagina tend to cause itching, irritation, burning with urination, and a white discharge. If the discharge is a different color and has a fishy odor there is a high probability you actually have a bacterial infection. In this case you should make an appointment to be seen in the office. If you suspect a yeast infection, we don’t discourage the use of over the counter yeast medicines such as Monistat. It is important to know that patients will frequently misdiagnose themselves and correspondingly, mistreat themselves.
