Peripheral neuropathies causing chronic pelvic pain.

Chronic pelvic pain is usually assumed to be visceral in origin by both patients and physicians. Because of the phenomenon of viscerosomatic convergence, it may be impossible to distinguish the origin without a meticulous history, physical examination, and nerve blocks. Error in diagnosis and treatment may lead to unhelpful surgery and poor results. Peripheral somatic neuropathies often mimic internal organ pathology. Similarly, visceral pathology can produce changes in peripheral somatic nerves that must also be addressed if maximum pain relief is to be attained. Awareness of peripheral neuropathies will favor more effective treatment for these patients.
