Occipital Nerve Block
What Is an Occipital Nerve Block?
The greater and lesser occipital nerves run from the upper cervical spine through the scalp to the top of the head. When these nerves become irritated or compressed, they produce a condition called occipital neuralgia — characterized by sharp, shooting, or throbbing pain at the base of the skull, the back of the head, and sometimes behind the eyes. An occipital nerve block is an injection of local anesthetic with or without corticosteroid administered around these nerves to interrupt pain signaling and reduce inflammation.
How It Works
Using anatomical landmarks or ultrasound guidance, the physician locates the occipital nerves as they emerge at the base of the skull. A small volume of local anesthetic — and often a corticosteroid — is injected around the nerve. The anesthetic immediately blocks pain signals, while the steroid reduces perineural inflammation over the following days, extending the duration of relief.
•Rapid onset: Local anesthetic begins working within minutes
•Anti-inflammatory: Steroid reduces nerve irritation for sustained relief
•Ultrasound guidance: Optional image guidance improves accuracy
•Bilateral blocks: Both sides of the head can be treated in a single visit if needed
What to Expect During the Procedure
•Preparation: You sit or lie face-down with the neck flexed; the scalp is cleaned and a topical or local anesthetic is applied
•Duration: 5–15 minutes — one of the shortest pain procedures available
•Guidance: Typically performed using anatomical landmarks; ultrasound used for precision cases
•Anesthesia: Local anesthetic at the skin surface; minimal discomfort
•Same-day recovery: No observation period required for most patients; driving is generally not restricted
Conditions Treated
•Occipital neuralgia
•Chronic migraine headaches
•Cervicogenic headaches (headaches originating from the neck)
•Cluster headaches
•Post-traumatic headache (e.g., after whiplash or concussion)
•Scalp tenderness and allodynia associated with migraine
Who Is a Good Candidate?
Patients with chronic headaches originating at the back of the skull — particularly those with tenderness over the occipital nerve pathway and pain that radiates forward toward the eye — are ideal candidates. This block is also useful for patients whose migraines have not fully responded to oral preventive medications.
Recovery & Results
Most patients tolerate the procedure extremely well with minimal post-procedure discomfort. Relief from the anesthetic may be felt within minutes. The steroid effect builds over 3–7 days, and many patients experience headache reduction lasting several weeks to months. Repeated injections every 2–3 months can be used for ongoing headache management. Some patients use the relief window to adjust migraine preventive medications in a lower-pain state.
Frequently Asked Questions
Q: Can occipital nerve blocks prevent migraines?
A: Yes — repeated occipital nerve blocks are used as a preventive strategy for chronic migraines. They reduce the frequency and intensity of attacks in many patients and are recommended in major headache management guidelines.
Q: Is the injection painful?
A: Most patients find this one of the more comfortable pain procedures. The injection is superficial (just beneath the scalp), and a local anesthetic is applied first. A brief stinging sensation may be felt.
Q: How often can I receive occipital nerve blocks?
A: Blocks can generally be repeated every 2–3 months. Your physician will develop a long-term management plan based on your response and the underlying headache diagnosis.
