The two most common causes of vulvar itching are vulvovaginitis and vaginitis. Vulvovaginitis means that the inflammation is confined to the vulva, which is characterized by redness, swelling or rashes at the vulva, and sometimes scratches due to itching. Vulvovaginitis can be treated with topical lotions and antibiotic ointment applied topically to the affected area. There are more types of vaginitis, and there are three most common types of vaginitis: trichomoniasis, bacterial vaginitis and mycosis fungoides. These types of vaginitis are different because the causative agent is different, so the clinical manifestations are also different. The main treatment for these three types of vaginitis is to choose a topical lotion, and then use a vaginal suppository inserted into the vagina for local treatment. But what kind of suppository is effective, it is best to go to the hospital to do a secretion test, know the causative bacteria and then use the right medicine to achieve better results.
