If there is odor and itching, it is often caused by bacterial vaginosis. It is recommended to rinse the vaginal secretions with 10% of cleanser and then insert a compound metronidazole pessary into the vagina once a day for 7 days. If the symptoms are not relieved after 3 days of medication, it is recommended to go to the hospital for routine examination of the leucorrhoea, mainly to find out whether there are other pathogenic infections, such as Candida infection. In clinical practice, it is necessary to take fluconazole capsules for 2 days, and to expose the underwear to the sun after scalding them with boiling water.
