There are many causes of perineal itching in women. It may be caused by the stimulation of perineal eczema spreading, or it may be caused by the stimulation of leukorrhea secretions from vaginitis, or it may be caused by vulvar malnutrition. Therefore, when a woman has perineal itching, she should go to the gynecological department of a hospital in time to confirm the specific cause of itching. If the routine examination of the leucorrhoea is confirmed to be caused by vaginitis, then the routine examination of the leucorrhoea will reveal abnormal cleanliness or the presence of other pathogenic bacteria, for example, if it is mycosis vaginalis, mold and spores will be detected, and if it is trichomoniasis, trichomonas will be detected. If it is diagnosed as mycosis fungoides causing perineal itching, the vulva can be washed with a compound cypress lotion and treated with nifurtimox vaginal soft capsules for symptomatic vaginal application. If trichomoniasis is the cause, oral tinidazole tablets and metronidazole suppositories can be used for vaginal topical treatment. If vulvovaginal dystrophy lesions are diagnosed, you can use a mixture of astragalus cream and trimethoprim to stop itching locally, or you can treat symptomatically with local physiotherapy. If you see significant perianal eczema that spreads to the perineum, you should visit a dermatologist and often consider symptomatic treatment with dermatoprost and other medications.
