How to describe pain of visceral nociceptive origin?
Visceral nociceptive pain arises from distention of a hollow organ. This type of pain is usually poorly localized, deep, squeezing, and crampy. It is often associated with autonomic sensations including nausea, vomiting, and diaphoresis. There are often cutaneous referral sites (e.g., heart to the shoulder or jaw, gallbladder to the scapula, and pancreas to the back). Examples of visceral nociceptive pain include pancreatic cancer, intestinal obstruction, and intraperitoneal metastasis.
