"Sympathectomy involves dissection of the main sympathetic trunk in the upper thoracic region thus interrupting neural messages that ordinarily would travel to many different organs, glands and muscles. It involves division of adrenergic, cholinergic and sensory fibers which elaborate adrenergic substances during the process of regulating visceral function." Journal of Applied Sciences Research, 6(6): 659-664, 2010

Impaired skin vasomotor reflexes have been found in patients with sympathetic dystrophies, dysautomias, post-regional sympathectomy and diabetic neuropathies

During surgery, for example, accidental sympathectomy can occur, leading to neuroma development and a predictable sequence of events: “internal” stimulation of afferent or somatosensory neurons, generation of efferent nerve impulses, and the subsequent sensation of neurologic pain.

Postsympathectomy pain of such severity that parenteral narcotics afforded no relief
Pain after operation was observed in thirty-four extremities by twenty-five of the patients (35 per cent). It began abruptly an average of twelve days after operation and was often accentuated nocturnally. The pain was almost always described as a deep, dull ache and persisted two to three weeks before spontaneously remitting.
Postsympathectomy pain of such severity that parenteral narcotics afforded no relief developed in two of these fifty-six patients and in nine additional patients. Treatment with carbamazepine produced dramatic reduction in the intensity of pain in seven of these nine patients within twenty-four hours after the institution of therapy. Two patients were given intravenous diphenylhydantoin and both experienced immediate relief of pain. The mechanisms of the syndrome and of the action of these drugs are uncertain. http://www.sciencedirect.com/science/article/pii/0002961074902384
Incidence of chest wall paresthesia 50.0% Paresthetic discomfort distinguishable from wound pain was described by 17 patients (50.0%). The most common descriptions were of ‘bloating’ (41.2%), ‘pins and needles’ (35.3%), or ‘numbness’ (23.5%) in the chest wall. The paresthesia resolved in less than two months in 12 patients (70.6%), but was still felt for over 12 months in three patients (17.6%). Eur J Cardiothorac Surg 2005;27:313-319
Ablation of the sympathetic nervous system is a standard model for the study of sympathetic nervous system regulation of immune function
These experiments indicate that an inflammatory response is not likely to be responsible for sympathectomy-induced immune alterations, eliminating a potential confounding factor in interpreting sympathectomy studies. Copyright 2001 Elsevier Science (USA).

Researchers have examined the role of autonomic feedback in emotional experience using the heartbeat detection paradigm. Katkin et al. (1982) found that some normal subjects can accurately detect their heartbeats, and it was those individuals who had a stronger emotional response to negative slides as determined by self-report (hantas et al. 1982) Experiments in animals demonstrate that sympathectomy may retard aversive conditioning (DiGusto and King, 1972) most likely because sympathectomy reduces fear. In order for feedback to occur, there must be a means for the viscera and autonomic nervous system to become activated. Clinical Neuropsychology By Kenneth M.
