If this happens once in a while, especially near the day of ovulation, it may be caused by ovulation pulling the ligaments in the adnexal area, which can be observed and does not require special treatment. However, if the pain is persistent or hidden, and it is also distended during non-menstrual periods, it may be caused by chronic pelvic inflammatory disease or adenomyosis, which requires a gynecological examination and Ultrasound examination is required. If pelvic inflammatory disease is identified, it is generally recommended to treat it with Chinese herbal enemas, combined with oral Chinese medicine, and the treatment course may be relatively long, requiring 2-3 cycles of treatment, each cycle taking 10-15 days.
