One of the main causes of vulvar pain is inflammation. When the body itself has gynaecological inflammatory diseases, the relevant pathogenic bacteria can easily infiltrate and invade the vulva area, triggering an inflammatory reaction, and the vulva area is rich in nerve distribution, when stimulated by inflammation, it will easily cause local pain and discomfort.
There is also the inflammatory reaction of chronic gynaecological inflammatory diseases themselves, some of which can also radiate and trigger pain in the vulva area.
