Abstract:
A 38-year-old woman presented with chronic left retro-orbital pain and photophobia. Palpation of the left occipital prominence revealed tenderness in the area of the greater occipital nerve and reproduced the eye pain. The diagnosis of cervicogenic headache was confirmed by symptom resolution following left greater occipital nerve blockade. The functional association between the greater occipital nerve and the trigeminal nerve provides a potential mechanism for this case of cervicogenic eye pain.
