If there is localized pain in the fallopian tubes during ovulation, it is not always clinically accurate to locate the pain in the adnexal area. The pain in the adnexal area may be caused by the following reasons: First, it may be due to inflammation, so it causes localized pain. Secondly, after ovulation, the corpus luteum is formed locally in the ovary, and the pressure inside the corpus luteum increases, so individual women who are more sensitive will have painful symptoms, most of which will be relieved or even disappear after a day or so. It is also recommended to have a gynecological examination to find out if there is an inflammatory reaction in the adnexal area or if there is a localized cyst in the ovary, and then give treatment according to the clinical results.
