The causes of this complaint are varied, and controversial aetiologies (musculoskeletal, neurological, psychological, mediastinal, pulmonary and gastrointestinal) have been suggested.3,4,6-9 ACP may result from cervical root compression, which can be confirmed by magnetic resonance imaging (MRI) findings
