Physical symptoms with uncertain medical explanations are some of the most common presentations in primary care. As many as 25% of visits to primary care physicians are prompted by physical symptoms that lack any clear organic pathology [1]. Although some patients with medically unexplained physical symptoms experience mild and/or transient discomfort, others experience substantial discomfort, distress, and impairment in functioning [2,3]. It is these patients, those with impairing physical symptoms of unknown etiology, who are often refractory to standard medical treatment and overuse medical services [2].
