Simple cervical erosion does not cause itching symptoms. Since cervical erosion is not a disease, if itching occurs, there are other problems involved. For example, some people experience itching due to inflammation of the vulva and vagina, which requires routine checks for vaginal bacteriology, classification of inflammation, and selection of targeted medications for treatment; others might have itching due to allergies, such as allergies to underwear, sanitary pads, or even semen; and there are also cases involving issues like vulvar lichen sclerosus.
