If itching occurs in the vulva after childbirth, it is clinically important to know how many days after childbirth it is, and if it is already 1-2 months after childbirth, to find out if there is any abnormal vaginal discharge. If there is tofu-like discharge, it is often caused by Candida albicans infection, which is a form of vulvovaginal pseudomycosis. In addition, if the vulva is itchy and the leucorrhea does not change, it is possible that the inflammatory reaction of the vulva is caused by the lack of timely replacement of sanitary napkins.
