Burning sensation in the vulva is commonly associated with vulvovaginitis and vaginitis. The cause of the disease should be clearly identified and treated, and common treatments include oral medications and topical medications. Trichomonas vaginitis, vulvovaginal pseudomycosis, and bacterial vaginitis may cause a burning sensation in the vulva, usually accompanied by other symptoms, such as abnormal leukorrhea. Treatment varies. Bacterial vaginitis, for example, can be treated with antimicrobial medications and oral medications such as metronidazole tablets. Metronidazole tablets can be used to treat bacterial vaginitis and trichomonas vaginitis and relieve the symptoms of excessive leukorrhea. You can also use a lotion to wash the vulva and insert a metronidazole suppository into the vagina under a doctor’s supervision. During the period of medication, pay attention to vulvar cleanliness, change underwear diligently, and avoid sexual intercourse. Women with burning sensation in the vulva should seek medical advice, and all medications need to be applied under the guidance of a doctor.
