title: Cluster headache pain vs. other vascular headache pain: differences revealed with two approaches to the McGill Pain Questionnaire.
abstract: We compared cluster headache pain and other vascular (migraine and mixed) headache pain on pain intensity ratings and the McGill Pain Questionnaire (MPQ). Cluster headache sufferers reported not only more intense pain and more affective distress, but also different pain qualities than did migraine and mixed headache sufferers. The pain qualities that best distinguished cluster headaches from other vascular headaches were the presence of punctate pressure and thermal sensations and the absence of dull pain. Although cluster headache sufferers and other vascular headache sufferers endorsed different sensory pain qualities, MPQ subscales proved no better than pain intensity ratings at distinguishing these two groups. This finding may have occurred because MPQ subscale scores include an intensity component and do not provide information about specific pain qualities such as that provided by MPQ sensory items. These findings provide evidence that cluster headaches are characterized by distinct pain qualities and are not simply a more intense version of the same vascular headache pain experienced by migraine and mixed headache sufferers. They further suggest than when the MPQ is used to assess specific pain qualities, sensory items and not the sensory subscale are the preferred units for analysis.
