Myofascial Pelvic Pain Syndrome
Myofascial Pelvic Pain Syndrome refers to pain in the muscles of the pelvic floor that is attributed to PFD. Sometimes it is called proctalgia fugax, coccygodynia, levator ani syndrome, pain in the muscles, or myalgia, can develop in three ways.
It may be caused by a direct injury to a muscle, a viscera-muscular reflex, or primary dysfunction in which muscles do not act in a coordinated manner. Direct injury may result from trauma, childbirth, or surgery.
Painful spasms of the muscles of the pelvic floor can occur because of musculoskeletal changes that occur with posture changes or low back pain.
Conversely, tension and pain in the pelvic floor can be the cause of mobility problems in the bony pelvis and sacroiliac joint.
PFD is often associated with other conditions that cause chronic pelvic pain. Conditions like interstitial cystitis (IC), irritable bowel syndrome (IBS) and endometriosis, for example, stimulate the nervous system which sends signals to the pelvic floor to contract. Chronic stimulation of the nervous system can cause the muscles to contract continuously. Muscle spasm and painful trigger points that occur in response to other organ problems are a type of problem caused by a viscera-muscular reflex.
Almost 90 percent of women with IC have pain in the muscles of the pelvic floor in conjunction with PFD, and at least half of women diagnosed with IC have IBS. About 85 percent of women with chronic pelvic pain have muscular spasm of the pelvic floor or postural changes.

Work-up
The diagnoses of pelvic floor dysfunction and pelvic floor tension myalgia are often overlooked. Complete evaluation of pelvic organs and the pelvic floor should be undertaken with a complete medical, surgical, and personal history, a thorough physical exam, and appropriate diagnostic testing depending on specific symptoms. Part of the evaluation includes a comprehensive exam of the pelvic floor musculature.
