If the leukorrhea is dry on the underwear and yellowish in color, this condition is often clinically without vulvar itching and is not accompanied by the odor of vaginal discharge or pain in the lower abdomen. The most common cause of this condition is due to local chronic inflammation of the cervix. When there is local chronic inflammation of the cervix, the local glands will secrete vigorously, resulting in increased secretions and a yellowish color. For this condition, it is possible to have clinical lumbosacral pain when the inflammation spreads to the sacral ligament. It is recommended to have a gynecological examination, in addition to the routine examination of the leukorrhea, it is also recommended to know whether the cervix is locally congested and edematous, with the manifestation of inflammation, and to know whether the sacral ligament is inflamed, so that active treatment can be given in the clinic.
