<li>
Greater occipital nerve (GON) block with local anesthetics is an alternate treatment option for headaches.</li>
<li>
Zhang <i>et al</i>. conducted a systematic review and meta-analysis of 7 randomized controlled trials assessing the efficacy of GON block for migraine.</li>
<li>
<!--?xml version="1.0" encoding="UTF-8" standalone="no"?-->Pooled outcome suggests that GON block:
<ul>
<li>
Reduces pain intensity (mean difference -1.24 [-1.98, -0.49], p=0.001)</li>
<li>
Decreases analgesia medication consumption (mean difference -1.10 [-2.07, -0.14], p=0.02)</li>
<li>
Has no significant impact on headache duration (mean difference -6.96 [-14.09, 0.18], p=0.06)</li>
</ul>
</li>
