It burns when i pee but i know for certain i don't have a yeast infection and i took a diflucan (fluconazole). why does it still hurt?

Med eval: If you are certain that you don't have a yeast infection than you should not be taking diflucan (fluconazole). It is important that this be evaluated. You might have a urinary tract infection. If you have a vaginal discharge - you could have bacterial vaginosis or a sexually transmitted disease. Please get medically evaluated. Take care.
