This course introduces the concepts of viscerosomatic pain that originates in visceral organs and is manifest by both visceral organ symptoms and body wall referred pain symptoms. These syndromes are common, often arising from the gastrointestinal tract. However, they are particularly troublesome in the pelvic region, and are associated with endometriosis, interstitial cystitis, and irritable bowel syndrome. They are frequently seen in patients with fibromyalgia or with abdominal/pelvic myofascial pain syndromes. This presentation addresses the underlying mechanisms, clinical presentation, and long-term management.
