Intercourse is a normal physiological activity that normally does not cause back pain or stomach pain. If such symptoms occur, they are usually caused by clinical pathology, such as pelvic inflammatory disease, endometriosis or pelvic tumor, inflammation of the cervix, which may lead to such symptoms. It is recommended to go to the hospital as soon as possible and have a gynecological examination to find out if there are redundant vaginal and cervical structures and local inflammatory reaction. If the cervix is locally congested, edematous, and has a lot of discharge, it is often caused by inflammation of the cervix, and when this inflammation reaches the sacral ligament, it can cause back pain and stomach pain. If there is inflammation in the pelvis and pressure pain in the uterine adnexa is found through gynecological examination, anti-inflammatory treatment should be actively given and it is best not to have intercourse until the inflammation is reviewed and it is not known whether the inflammation is healed.
