Outcome Measures
Primary Outcomes (1)
Change in Numeric Rating Scale (NRS) Pain Score
Pain intensity will be assessed using a NRS marked from 0-10 with fixed intervals, with 0=no pain, and 10=worst pain.
baseline, 4 weeks
Secondary Outcomes (3)
Change in number of patients with medication overuse
baseline, 4 weeks
Change in number of headache days per month
baseline, 4 weeks
Change in Headache Impact Test (HIT-6) Score
baseline, 4 weeks
Study Arms (2)
Ultrasound Guided GON Block at C2
EXPERIMENTALUltrasound Guided Greater Occipital Nerve Block at C2
Landmark based GON Block
ACTIVE COMPARATORLandmark-Based Greater Occipital Nerve Block
Interventions
Ultrasound guided injection
Traditional landmark-guided technique at the superior nuchal line. This approach relies solely on superficial bone-based anatomic landmarks to infiltrate local anesthetic and corticosteroid around the nerve at the level of the superior nuchal line.
Eligibility Criteria
You may qualify if:
- Unilateral or bilateral headache symptoms attributed to occipital neuralgia or cervicogenic headache as defined by the International Headache Society's International Classification of Headache Disorders (3rd edition beta version)
- Age 18 years and older (no upper age limit defined)
- Imaging of cervical spine within last year (either x-ray, MRI or CT)
You may not qualify if:
- History of cervical spine surgery, trauma, or surgical procedure involving head or neck during the last year
- Use of new preventative medications 1 month prior or during study enrollment
- Evidence of impaired sensation in the GON dermatome region (posterior scalp to the vertex of the cranium) from neurological, dermatological, or other disease process
- Evidence of cranial defect or other anatomical abnormality near the target injection site
- History of bleeding diathesis, coagulopathy, or current use of anticoagulant medications
- Pregnancy
- History of adverse reaction or allergy to local anesthetic agents or corticosteroids
- Occipital nerve block within the past three months.
- Unavailability for appropriate follow-up throughout the whole duration of study
