Left lower abdominal pain and discomfort in the waist, accompanied by dark menstrual blood, may be caused by the following reasons:
1. This may be related to the female reproductive system, such as dysmenorrhea during menstruation, which is caused by uterine contractions expelling the endometrium, resulting in abdominal discomfort.
2. It could be pelvic inflammatory disease, such as salpingitis or ovarian cysts, which can cause abdominal pain and lower back pain.
3. Endometriosis can also lead to similar symptoms, where endometrial tissue grows outside the uterus, causing cyclical pain.
4. Dark menstrual blood may result from blood remaining in the body for an extended period, leading to increased oxidation. It can also be related to lighter menstrual flow and slow blood discharge. However, if the pain is severe or persistent, or if it is accompanied by symptoms such as fever, abnormal discharge, or painful bowel movements, this may indicate a more serious condition, and prompt medical attention is advised.
