There are many reasons for strong itching of the vulva a few days before menstruation, and its specific treatment needs to be analyzed and judged depending on the specific condition. The days before menstruation are the luteal phase, when the hormones in a woman’s body fluctuate greatly and can lead to increased leucorrhea, which may cause vulvar itching and other symptoms if no attention is paid to hygiene. Patients can go to a pharmacy and buy a lotion, such as Gynecare or Jelqing, and wash the vulva with a diluted solution of 1:10. If it does not get better effectively, it may be caused by gynecological inflammation, commonly mycotic vulvovaginitis, trichomonas vaginitis, mycoplasma infection, chlamydia infection, etc.; it may also be vulvar pruritus. Patients are advised to go to the gynecology department of the hospital for relevant examinations in order to clarify the cause and carry out treatment. In addition, patients should pay attention to personal hygiene in daily life, change underwear regularly, do not recommend frequent use of pads, and keep the vulva dry and clean to prevent bacterial growth, which can lead to vulvovaginal inflammation and vulvar pruritus.
