If the vaginal area is swollen and painful, most patients suffer from vaginitis or other diseases, such as bacterial, trichomonas, mycoplasma, chlamydia or other pathogens, which can cause irritation of the vaginal wall, causing congestion and edema. If a woman’s vaginal area is subjected to strong external stimulation, such as accidental fall, bumping or improper force during sex, it can also cause damage to the vaginal wall, resulting in edema, which needs to be treated by the obstetrics and gynecology department of the local public hospital in time to avoid delaying treatment.
