Any advice for a yeast infection that won't go away?

See a doctor: If you haven't already, you need to have an exam. You may have a different infection causing your symptoms. Occasionally, yeast may be resistant to the common treatments. These may require a broader spectrum antifungal, such as terconazole, if Monistat or Diflucan (fluconazole) don't help. Be sure to get an accurate diagnosis first.
