Doctor's answer:

Hello, based on the description of the above content, your condition is likely vaginitis, which is common in girls under the age of 5 and often coexists with vulvitis. The main symptoms include an increase in vaginal discharge, which is purulent, leading to vulvar pain. Some children may also develop urinary tract infections, presenting with symptoms such as urgency, frequency, and dysuria.
Treatment principles: Maintain cleanliness and dryness of the vulva, select appropriate oral antibiotics targeting the pathogen, provide symptomatic treatment, administer deworming treatment if pinworms are present, promptly remove any foreign bodies in the vagina, and apply estrogen cream externally for labial adhesion. In severe cases, separation of the adhesion may be necessary.
