Itchy vulva and yellowish leucorrhea are considered to have the possibility of vulvodynia and vaginitis. Vulvodynia and vaginitis are common gynecological diseases, usually related to trichomonas, mycobacteria, bacteria, mycoplasma and other pathogenic microbial infections. Inflammation of the vulva and vagina leads to an increase in the amount of mucus secreted from the vagina and cervix, as well as an increase in the amount of epithelial cells shed in the vagina. Therefore, vaginal secretions will increase, appear yellowish and irritate the skin mucosa with symptoms of itching and burning pain in the vagina. It is recommended to choose the appropriate topical lotion and vaginal suppositories according to the type of pathogenic infection. It is recommended to pay attention to perineal hygiene, clean the perineum with warm boiled water and do not use gynecological lotions.
