Headache is one of the most common reasons for patients to access healthcare. Greater occipital nerve (GON) block with local anesthetic and steroid has been described for the management of primary headache refractory to conventional treatment. Two ultrasound (US)-guided techniques for greater occipital nerve (GON) block have been described for the management of refractory headache syndromes: a proximal technique performed at the level of the second cervical vertebra and a distal technique performed at the level of the superior nuchal line. Our airm is to compare the accuracy, efficacy and safety of these two techniques in patients with refractory headaches.

Eligibility |
Inclusion Criteria: 1. Features suggestive of occipital neuralgia: pain that begins in the upper neck and back of the head with radiation forward toward the eye and has an aching or burning character. 2. Diagnosis of refractory primary headache, any type 3.

Primary | Numerical rating score (NRS) for headaches | One month | ||
Secondary | Efficacy-Related Outcomes | This would include NRS for headache at 24 hrs and 3 months after the intervention, patient satisfaction with the block, Hospital Anxiety and Depression Scale at 1 month compared to baseline, SF-36 Short Form Health Survey to measure improvement in functional status compared to baseline, quality of sleep and average hours of restful sleep at night. | 24 hours and 3 months | |
Secondary | Performance-Related Outcomes | We will measure performance time from contact of US probe with skin to the end of the procedure, procedural discomfort as rated by NRS, number of needle re-adjustments and evidence of sensory block as confirmed by the loss of pin-prick sensation in the dermatomal distribution of GON, and visualization of GON. | During procedure | |
Secondary | Safety-Related Outcomes | Any immediate post intervention complications will be recorded (e.g. hematoma, vascular puncture, dizziness). Occurrence of any long-term adverse effects (e.g. infection, numbness, alopecia) will be recorded at 1 month following the intervention. | Immediate post-procedure and at 1 month |
