If the vulva is itchy and the leucorrhea is sticky, it is most commonly caused by vaginal inflammation, but when there is inflammation in the vagina, the discharge increases, so it causes local itching due to local stimulation of the vulva by the discharge. In addition, if this inflammation is clinically due to Candida infection, trichomonas infection, or mycoplasma or chlamydia infection, then it may also lead to local allergy, so it may also lead to local itching of the vulva. It is advisable to do routine laboratory tests to find out whether the inflammatory reaction is caused by the above-mentioned pathogenic infection, and to give timely medication, most of which can achieve a complete cure, and it is also recommended to keep the vulva locally clean during the period of illness, and not to drink alcohol and eat spicy, acidic and stimulating food.
