Women’s inguinal lymph node pain is usually related to infection, mostly seen in lymphadenitis, gynecological diseases, venereal diseases and so on. 1. Lymphadenitis: Infection of the lower limbs, vulva and other places, the inflammatory factor will enter the lymphatic vessels through the lymphatic space, so that the lymph nodes have non-specific inflammation. 2. Gynecological diseases: such as pelvic inflammatory disease, adnexitis and other bacterial infections, can flow into the lymph nodes through the lymphatic vessels, causing inflammatory reaction of the lymph nodes and pain symptoms. 3. Sexually transmitted diseases: such as gonorrhea, condyloma acuminatum and other viral infections, when the pathogens are too much to be cleared by the local lymph nodes, they will be transferred to the inguinal lymph nodes along with the lymphatic fluid, resulting in inflammation and pain in the inguinal lymph nodes. It is recommended that women with painful inguinal lymph nodes go to the hospital in time to clarify the cause of the disease and under the guidance of the doctor to carry out standardized treatment, so as not to delay the disease to bring adverse effects on the body.
