Pain in Gilles de la Tourette syndrome and related tic disorders.
Although pain is not generally recognized as a symptom of tic disorders, we have seen a number of patients in whom this was a prominent feature, at times even the symptom of greatest concern. The commonest pain complaints are those arising from the actual performance of a tic. Most often this follows directly from the discomfort produced by sudden or repeated extreme exertion. Here the origin of the pain is usually musculoskeletal, though rare examples of neuropathic pain may occur. Pain also may arise from striking or being struck by a moving body part involved in large amplitude tics. Other related painful acts include deliberate self-injury and pain inflicted upon others. A second major category is represented by a smaller number of patients who complain of pain during voluntary efforts to suppress their tics. Finally, there are patients who obtain relief from tics while experiencing pain, to such an extent that they will deliberately provoke pain to obtain its benefit. We feel that pain should be recognized as a common complaint, and occasionally a source of significant disability, in patients with tics.
