VISCERAL PAIN

Visceral pain is transmitted by C fibers that are found in muscle, periosteum, mesentery, peritoneum, and viscera. Most painful stimuli from abdominal viscera are conveyed by this type of fiber and tend to be dull, cramping, burning, poorly localized, and more gradual in onset and longer in duration than somatic pain. Because abdominal organs transmit sensory afferents to both sides of the spinal cord, visceral pain is usually perceived to be in the midline, in the epigastrium, periumbilical region, or hypogastrium (Fig. 10-1). Visceral pain is not well localized because the number of nerve endings in viscera is lower than that in highly sensitive organs such as the skin and because the innervation of most viscera is multisegmental. The pain is generally described as cramping, burning, or gnawing. Secondary autonomic effects such as sweating, restlessness, nausea, vomiting, perspiration, and pallor often accompany visceral pain. The patient may move about in an effort to relieve the discomfort.



Figure 10-1. Localization of visceral pain. Pain arising from organ areas depicted in 1, 2, and 3 is felt in the epigastrium, midabdomen, and hypogastrium, respectively, as shown in A. The arrow in A indicates biliary pain that is referred to the right scapular area.
