Lower abdominal pain after menstruation suggests possible pelvic inflammatory disease or adnexal inflammatory disease. In this case, it is necessary to go to the hospital for ultrasound examination to determine whether there is inflammatory fluid in the uterus, both adnexa and pelvis, as well as gynecological internal examination to determine whether there is pressure pain in the abdomen. At this time, anti-inflammatory drugs should be taken according to the situation, and the symptoms can be slowly relieved after about 7-10 days of oral medication. It is recommended not to be overly anxious or nervous. If it occurs only once in a while and there are no obvious problems after examination, it will not affect your health. At the same time, if vaginal inflammation occurs in life, it should be treated actively because vaginal inflammation can cause upstream infection, which can aggravate the symptoms of pelvic inflammatory disease.
