Most of the vulva itching in girls comes because of vaginitis, so it is important to see if the vaginal discharge is normal. If the discharge is a lot, beanbag-like, or if there is a foamy yellow-green discharge, then it is time to go to the hospital to check the leucorrhoea and see which kind of vaginitis it is. If it is trichomoniasis, both the partner and the girl should take oral metronidazole for seven days and then vaginally on metronidazole-type medication. If it is mycosis vaginalis, then the vagina should be put on clotrimazole vaginal tablets, or povidone suppositories, etc. If it is bacterial vaginitis, then it can also be treated with metronidazole gel, metronidazole effervescent tablets, etc. Once the vaginitis is under control, the vulva itching will naturally improve and the symptoms will be significantly reduced.
