If the vaginal opening is a little itchy, you can use Paregoric Pine ointment or Mometasone ointment applied to the vaginal opening to stop the itching. It is recommended that you must go to the hospital the next day for the appropriate tests, mainly to find out which pathogenic bacterial infection is causing the itching. If it is Candida infection, you can use Dacrynic soft capsule to insert into the vagina. If it is Trichomonas infection, it can be treated with metronidazole. If the infection is mycoplasma or chlamydia, it can be treated with azithromycin. If it is vulvar dystrophy, it is recommended to alternate topical dermatoprost and progesterone ointment, which will also have a clinically significant antipruritic effect. If the itching is caused by vulvar eczema, topical application of mometasone or paregoric ointment for 3-5 consecutive days will basically eliminate the clinical symptoms.
