What kind of doctor is treating you? Have you been screened for diseases that increase risk of yeast infections, such as diabetes or a weakened immune system ? Has you discussed with your doctor treating a sexual partner? In unusual cases, yeast infections can be passed back and forth sexually. Have you had a vaginal micro biome test? Has a fungal culture been done? If the yeast is resistant to fluconazole, perhaps there is a cheaper alternative that it is sensitive to? I’m just thinking out loud about ways to treat you effectively without breaking the bank.
