First of all, gynecological inflammation is considered as the pelvic cavity is continuously congested during menstruation and when inflammation exists, it causes local tissue irritation, congestion and swelling, resulting in pain. If the fallopian tubes are blocked or if there is fluid accumulation in the tubes, there is also pain. Secondly, women with tubal tuberculosis have cramping pain, mainly in the lower abdomen, which is relatively mild. Moreover, women with endometriosis can also cause pain. Due to the implantation of the endometrium of the fallopian tube, the normal menstrual cycle of women is altered, resulting in obstacles in the transportation of eggs by the fallopian tube, which not only causes pain during menstruation, but also affects women’s fertility. Finally, women who have intercourse or consume overly stimulating foods during their periods are also prone to pain on both sides of the fallopian tubes.
