Itchy scratching and swelling below is a case of vaginal inflammation. Vaginal discharge stimulates the vulva and causes itching and swelling of the vulva after giving a scratch. It is necessary to go to the hospital to test the discharge, determine the type of vaginal inflammation and choose the medication vaginally to treat vaginitis, otherwise the persistence of vaginitis will keep stimulating the vulva with itching. When the type of vaginitis is determined, choose the medication, for example, trichomoniasis and bacterial vaginitis, you can vaginally apply metronidazole suppositories, and after the medication, you can apply erythromycin ointment on the vulva to reduce inflammation and swelling. In case of mycotic vaginitis, clotrimazole suppositories can be applied vaginally and the vulva will gradually return to normal after the vaginitis is cured in a week’s time.
