A pain like no other: From cluster to headache to Eagle's syndrome, a case report.

Background: Eagle's syndrome, also called stylohyoid complex syndrome, is a rare syndrome pathology characterised by latero-cervical pain radiating to the face, linked to an abnormal enlargement of the styloid or calcification of the stylo-hyoid ligament.
