Greater Occipital Nerve Block for Migraine Prophylaxis
Migraine is a common neurological condition that can be disabling, particularly if chronic. Greater occipital nerve (GON) block has been utilized for decades for the treatment of migraine in the absence of a single randomized, placebo-controlled trial documenting its effectiveness. Hypothesis: Greater occipital nerve block reduces the frequency of days with moderate or severe headache in patients with episodic or chronic migraine.
