If : If a patient has a yeast infection, then it usually has white or cheesy discharge, the vagina appears to have white dots/spots on it, and it is very itchy. There are over the counter treatments available for treatment; either suppositories or cream can safely treat a yeast infection. If the patient has any concern about sexually-transmitted infections causing infection, these infections usually have yellow or green discharge, and the patient often has pain and fever, then the patient must have a medical evaluation. To prevent yeast infections, use cotton underwear only (not nylon), avoid hot baths, and decrease sugary drinks/snacks in the diet.
