Supplementary Material for: Migraine symptoms induced by an auricular piercing in a 27 year old female: a case report

Introduction. Migraines are common, debilitating, and have high direct and indirect costs. They can be difficult to treat, and many patients make use of alternative medicine techniques. One of these is acupuncture applied to locations on the auricle thought to modulate migraine symptoms. Some patients obtain piercings in these locations in hopes of relieving their symptoms, however, the literature does not address the possibility of migraine symptoms being worsened or even induced by such piercings.
Case presentation. We present a case of a 27 year old female with a history of transient hemiplegia without headaches who developed headaches, visual disturbances, and nausea after a piercing of the inferior crus of her left antihelix (known as a rook piercing). No abnormalities were found on workup, and symptoms were treated with supportive care. After removing the piercing nine months later, the patient’s symptoms resolved.
Conclusion. The mechanism linking the piercing with the migraine symptoms is unclear, but may involve modulation of trigeminal or vagal pain pathways, as both of these cranial nerves innervate this area of the auricle. Regardless, in patients presenting with migraine symptoms, history and physical exam should not overlook piercings as potential contributory factors.
