If a virgin has mycosis vaginalis, she can be treated with the following methods: 1) Oral fluconazole, which can inhibit the growth of mycobacteria and play a therapeutic role. 2) Sitz bath with 5% sodium bicarbonate, twice a day for 10-15 minutes, which can enter the vagina through the vulva and inhibit the growth of Candida and change the acidic environment in the vagina, which will improve the clinical symptoms. After each sitz bath, dry the vulva and apply clotrimazole ointment or dacrynic cream locally for treatment, which will significantly reduce the symptoms and achieve the purpose of cure.
