Myofascial headache

ABSTRACT

Pericranial myofascial tenderness is a common phenomenon in primary headache. Nociception from pericranial muscles may play a role in provoking or aggravating headaches. Conversely, the central mechanisms of headache are also important in myofascial headaches. Myofascial headaches resulting from pericranial musculoskeletal dysfunction may stem from the referred pain caused by central convergence and facilitation. This review comprehensively evaluates myofascial headache in comparison with other primary headaches.
