The recurrence of mycobacteria may be related to the poor resistance of women, or it may be related to the lack of hygiene in the vulva, the rainy and humid local environment, and the inability to dry the underwear. If mycobacteria recur 3 times in a year, it can be called complicated mycobacterial vaginitis. It is best to use regular medication for 3 months, each time 3 days after menstruation, rinse the vagina with cleanser, use nifurtimycin vaginal soft capsule to plug the vagina for a week, then use Lactobacillus vaginalis to plug the vagina for 5 days, next 3 days after menstruation, then start to plug the medication, and so on. If your underwear is more than 3 months old, it is best to change and wash them again. Take boiling water to wash your underwear every day and take them to the sun after washing.
