The itchy vulva can be coated with dermaplanin, paregoric pine or mometasone ointment, which will achieve a better anti-itch effect, but not to achieve the purpose of the root cause. The itchy vulva can go to the hospital to do the appropriate examination to understand whether the vulva has pubic lice, whether there are grayish-white cauliflower-like growths, whether there is local redness and swelling, whether there is herpes, and then do the appropriate examination, and also to understand whether there is a lot of vaginal discharge, because vaginal inflammation can also cause local allergies in the vulva, so there will be symptoms of itching. If necessary, we can do a routine laboratory test of the white belt with a high-powered microscope to find out the causative organism and then give the appropriate medication to cure the symptoms of vulvar itching completely.
