Mechanical sensitivity changes in pericranial muscles after local anesthesia and experimentally induced pain in the temporalis tendon: Implications for headache and facial pain.

These findings suggest that the therapeutic effect of temporalis tendon anesthetic injections on facial pain and headaches are most likely not only due to a direct effect of the local anesthetic on the temporalis tendon but rather to a more generalized block of the nerves in the area. In addition, the temporal tendon may contribute to the pathophysiological processes of headache.
