There are more causes of pain in the lower right abdomen in women. There is a possibility of pregnancy in the lower right side of the abdomen with hidden pain, but it cannot be determined based on this sign and needs to be combined with the appropriate tests. Some of the more common causes of right lower abdomen usually include organs of the pelvis, pelvic organs including uterine adnexa, some lesions of the urinary system including bladder and ureter, and even lesions of the intestinal tract, which can also cause pain in the right lower abdomen. Therefore, pain in the right lower abdomen usually has to be considered in combination with several etiologies. Chronic appendicitis, acute attacks of appendicitis, ureteral stones, cystitis, ureteritis, ureteral lesions, pelvic inflammatory disease, luteal cysts of the uterine adnexa, rupture of the corpus luteum, ectopic pregnancy, early pregnancy, all of which may lead to the presence of vague pain in the right lower abdomen. Therefore, a differential diagnosis should be made clinically, including HCG test, abdominal ultrasound as well as ultrasound of the lower abdomen, and corresponding tests such as routine blood and urine tests, which need to be combined with gynecology, surgery and urology to make a comprehensive diagnosis.
