PURPOSE: To evaluate the repetitive occipital nerve blocks using a nerve stimulator in the treatment of cervicogenic headache. METHODS: This prospective noncomparative clinical interventional case-series study included 47 patients suffering from cervicogenic headache using a repetitive guided occipital nerve blockade. RESULTS: Forty-one patients (87%) required more than one injection to achieve six-month pain-relief period. For every three years of headache history, the outcomes demonstrated that a patient needed one additional injection to the basic injection. CONCLUSION: The repeated nerve stimulator-guided occipital nerve blockade is a treatment mode that may relieve cervicogenic headache with no recurrence for at least six months in addition to alleviation of associated symptoms.
