Chiropractic Adjustment and Occipital Neuralgia: Risk Assessment

Occipital neuralgia—paroxysmal, lancinating pain in the greater/lesser occipital nerve distributions—can be triggered or exacerbated by high-velocity, low-amplitude (HVLA) cervical spine manipulation, though permanent nerve injury is rare.

Potential Mechanisms

• Transient nerve stretch/compression during thrust maneuver.
• Exacerbation of pre-existing entrapment at C2 facet, obliquus capitis inferior, or fascial tunnel.
• Vertebral artery dissection (VAD): Rare (~1:20,000–1:250,000 manipulations) but catastrophic; presents with occipital/neck pain, neurologic deficits — emergency.

Typical Post-Adjustment Course

• Mild soreness/stiffness resolving in 24–48 hours — common, benign.
• New or worsening occipital neuralgia, cranial nerve deficits, dysphagia, ataxia, vertigo, diplopia → urgent imaging (MRI/MRA) and neurologic evaluation.

Chiropractor Responsibilities

• Screen for red flags (vascular, neoplastic, infection, connective tissue disorder) before cervical HVLA.
• Use minimal force techniques for patients with osteoporosis, rheumatoid arthritis, prior cervical surgery.
• Informed consent including VAD risk.

Patient Action

If you develop new occipital neuralgia after manipulation, consult a neurologist or headache specialist. Do not assume it's "just soreness" if it persists or worsens.
