For vulvar itching, increased leukorrhea and yellowing, first wash the vulva with water, pay attention to vulvar hygiene and sanitation, change underwear and panties regularly, do not wear tight-fitting clothes and pants, and keep the vulva clean and dry. If symptoms are relieved after the above treatment, no special treatment is needed. If the symptoms are not relieved after the above treatment, further laboratory examination of vaginal secretion is needed. Depending on the results of the laboratory tests, the next step of treatment will be decided. For mycosis fungoides, topical miconazole suppositories should be used in the vagina. For bacterial vaginitis, topical metronidazole suppositories should be used. For trichomonas vaginitis, couples should be treated together with oral metronidazole tablets and localized vaginal metronidazole suppositories.
