Common Symptoms
- Unilateral headache originating from the occipital/suboccipital
region
- Pain triggered or worsened by neck movement or sustained posture
- Reduced range of cervical motion
- Ipsilateral shoulder and arm pain in some cases
- Absence of throbbing quality (unlike migraine) — usually
non-pulsatile
- Headache precipitated by sustained forward head posture (screen
work)
- Suboccipital tenderness on palpation
Common Causes
- C2–C3 zygapophyseal (facet) joint arthropathy
- Atlantoaxial joint arthritis or instability
- Whiplash-associated disorder
- Prolonged forward head posture — screen use, driving
- C3 dorsal root ganglion irritation
- Greater occipital neuralgia — compression of the GON
- Suboccipital muscle trigger points (rectus capitis posterior)
Conservative & First-Line Treatment
- Physiotherapy — cervical spine mobilisation, deep cervical flexor
strengthening
- Postural correction and ergonomic assessment
- NSAIDs and tricyclic antidepressants (amitriptyline)
- Heat therapy to suboccipital muscles
- Sleep hygiene and pillow positioning
How Vedant Pain Management Clinic Can Help
Our interventional pain specialists offer the following evidence-based
procedures, all performed with real-time ultrasound guidance for precision and
safety:
- Ultrasound-guided Greater Occipital Nerve (GON) block — one of the most
effective treatments for cervicogenic headache and occipital neuralgia
- C2–C3 medial branch nerve block under image guidance
- C2–C3 facet joint medial branch Radiofrequency Ablation (RFA) for
sustained relief in confirmed cervicogenic headache
- Cervical Epidural injection for C2–C3 nerve root irritation
- Atlantoaxial joint injection (image-guided) for upper cervical
arthropathy
- Suboccipital muscle and semispinalis capitis trigger point injection
- Botulinum toxin injection for cervicogenic headache with associated
muscle tension component
Newer Diagnostic Concepts & Advances
The Third Occipital Nerve (TON) headache — arising from the C2–C3
zygapophyseal joint — is now recognised as a distinct and common entity,
particularly post-whiplash. Medial branch block of the TON with positive
diagnostic response followed by medial branch RFA offers lasting relief,
distinct from standard greater occipital nerve treatment.
