The Role of the Cervix in Menstrual Pain


When women think of menstrual cramps, we normally think of the constant ache or throbbing pain in the pelvis. We seldom think cervix, but it is a key player in menstrual cramps.

During menstruation, the lining of the uterus detaches and exits the body through the cervix. The cervix is the opening to the uterus. In its natural, midline position, it opens slightly, allowing menstrual blood to pass into the vagina.

When adhesions form around the cervix or within its tissues (as pictured in the zoombox), the opening of the cervix can become narrowed.

But if the cervix has been damaged or adhesions have formed on or near the cervix, the cervix can elicit a great deal of pain during menstruation. If the cervix is pulled or pushed forward, backward, or to one side, it can make the passage of menstrual blood difficult and painful. If adhesions have formed on or near the cervix, the opening of the cervix can be constricted. When blood tries to pass through the constricted opening, it can elicit a great amount of pain.

Because the cervix is protected inside the vagina, many women are not aware of how easily the cervix can be damaged. Sexual intercourse or sexual abuse can physically push the cervix out of alignment. Any surgery in the pelvis can cause adhesions to form that constrict the cervix. Sexually transmitted diseases can create inflammation that leads to adhesion formation. STDs can also inflame the cervix, making the passage of menstrual blood painful. Radiation therapy causes the same process of adhesion formation and can leave the entire pelvis adhered. Even vaginal or yeast infections can lead to adhesion formation that constricts the cervix or pulls it out of alignment.

Many women who have adhesions in their reproductive tract or have cervixes that are out of alignment also experience pain during sexual intercourse. The same adhesions that constrict the cervix can also constrict the vaginal walls, leading to pain when stretched.

Conventional treatment for adhesions involves laparoscopic surgery to lyse (burn) any adhesions. However, few women are willing to undergo surgery in a very delicate, personal area when their chief complaint is menstrual pain.

Clear Passage Therapies (CPT) offers a unique and effective alternative that directly treats adhesions and the cervix. Using manual physical therapy techniques, CPT therapists deform and detach adhesions. They also gently enable the cervix to move back to its natural position. Following treatment, may women report that their menstrual pain is significantly decreased or gone. Many women who previously experienced pain with intercourse also report that sex is no longer painful.
