If a woman has cervical adhesions, there are no specific symptoms when she does not have a menstrual period, but only when she has a menstrual period will she experience persistent pain in the lower abdomen and no menstrual blood is discharged. The so-called cervical adhesions, in fact, is the blockage of the cervical canal adhesions, thus affecting the discharge of menstrual blood, often occurring in women after abortion, or after the removal of the uterus, after the occurrence of cervical adhesions, if there is no menstrual flow, there are often no special symptoms, so there is no way to confirm the diagnosis. There is a persistent cramping pain in the area and a feeling of swelling, and no menstrual blood is discharged from the vagina. However, there are symptoms of menstruation, which may lead to back pain, irritability, and even facial acne. So for 30 to 40 days after abortion without menstruation but with persistent lower abdominal cramping pain, the first thing to consider is caused by cervical adhesions, then you only need to go to the hospital gynecology department for ultrasound to confirm the diagnosis of cervical adhesions, the cervical canal and the cavity of the uterus have obvious accumulation of fluid sludge, which is actually menstrual blood sludge. Since there is no way to remove the adhesions through medication, surgery is the only treatment that can be considered.
