What to Expect
Pre-procedure assessment
Estimated time: 10 minutes
Dr. Orr confirms the indication for the nerve block based on your headache pattern, reviews your medications including blood thinners, and explains the procedure, expected response, and potential side effects.
Nerve localization and injection
Estimated time: 5 minutes
You sit or lie face down. Dr. Orr palpates the occipital nerves at the base of the skull and injects a mixture of local anesthetic and corticosteroid at the greater and lesser occipital nerve locations bilaterally. The injection takes about two minutes.
Post-injection monitoring
Estimated time: 10 minutes
You rest for 10 to 15 minutes while the local anesthetic takes effect. Temporary numbness at the back of the head is expected and confirms correct needle placement. You can drive and return to normal activities afterward.
Follow-up assessment
Estimated time: 5 minutes
Pain relief typically begins within hours and may last days to weeks depending on your response. Dr. Orr evaluates the degree and duration of relief at a follow-up visit to determine whether repeat blocks or alternative treatments are appropriate.
Occipital Nerve Block
An occipital nerve block is a targeted injection at the occipital ridge that interrupts pain signaling from the greater and lesser occipital nerves. Used for occipital neuralgia, cervicogenic headache, and migraine with occipital predominance. $175 per side.
Available at our St. Marys, Georgia clinic.
Why the Occipital Nerves Matter
The greater occipital nerve arises from the dorsal ramus of C2 and ascends through the semispinalis capitis and trapezius muscles before crossing the superior nuchal line to innervate the posterior scalp as far forward as the vertex. The lesser occipital nerve, derived from the ventral ramus of C2, travels along the posterior border of the sternocleidomastoid to supply the lateral occipital and retroauricular regions.
These nerves are vulnerable to compression, irritation, and sensitization at several points along their course — particularly where the greater occipital nerve pierces the semispinalis capitis and the tendinous aponeurosis of the trapezius. Chronic muscle tension, cervical spine pathology, prior trauma, and central sensitization can all drive persistent pain in the occipital nerve distribution. When that pain becomes self-sustaining, a peripheral nerve block can interrupt the cycle.
The block also has diagnostic value. If anesthetizing the occipital nerves eliminates the patient’s headache, it confirms that the occipital nerves are involved in the pain generator. This distinction matters clinically: it separates occipital neuralgia from headache disorders that overlap in presentation but arise from different mechanisms.
How the Procedure Works
Dr. Orr performs occipital nerve blocks using a landmark-based technique. The greater occipital nerve is located at the medial third of a line drawn between the external occipital protuberance and the mastoid process, where the nerve is typically palpable as it crosses the superior nuchal line. The lesser occipital nerve is targeted approximately one-third of the distance laterally along the same line.
A small volume of local anesthetic — typically 2 to 3 mL of 0.5% bupivacaine per nerve — is injected at each site. Depending on the clinical scenario, Dr. Orr may add a corticosteroid such as methylprednisolone or triamcinolone to extend the duration of relief. The anesthetic provides immediate feedback: numbness in the occipital distribution within minutes confirms accurate placement.
The entire procedure takes 10 to 15 minutes and is performed in the office without sedation. Patients can drive themselves home and return to normal activity immediately. The most common sensation is brief pressure at the injection site, followed by numbness over the posterior scalp that resolves over several hours.
What the Evidence Shows
Occipital nerve blocks have been used in headache medicine for decades, and several lines of evidence support their role across multiple headache types. Afridi et al. (2006) demonstrated that greater occipital nerve block with lidocaine and methylprednisolone reduced headache severity in patients with chronic migraine, with a response rate exceeding 50% in their cohort. The effect was not limited to patients with occipital pain, suggesting that the block may modulate central trigeminocervical processing rather than acting solely as a peripheral analgesic.
Dach et al. (2015) compared greater occipital nerve block with botulinum toxin injections for chronic migraine and found comparable efficacy at 12 weeks. This is clinically relevant because occipital nerve block is substantially less expensive, faster to administer, and can be repeated at shorter intervals when needed.
For cluster headache, Inan et al. (2001) reported that greater occipital nerve block reduced attack frequency in episodic cluster patients, positioning it as a useful adjunctive treatment alongside standard abortive and preventive therapies. In post-traumatic headache and post-concussion syndromes, the block is frequently used when the headache phenotype involves the occipital distribution, particularly when cervicogenic mechanisms are suspected.
Clinical Applications
Dr. Orr uses occipital nerve block for headache disorders where the occipital nerves contribute to pain generation or central sensitization.
Occipital Neuralgia
Sharp, shooting pain in the distribution of the greater or lesser occipital nerve. The nerve block is both diagnostic and therapeutic, confirming the nerve as the pain source while providing immediate relief.
Cervicogenic Headache
Headache arising from the upper cervical spine and referred to the occiput and posterior scalp. The C2 origin of the occipital nerves makes them a direct target when cervical pathology drives the headache.
Migraine with Occipital Predominance
Migraine that localizes to the posterior head. Blocking the occipital nerves may modulate trigeminocervical convergence, reducing migraine frequency and intensity beyond the duration of the anesthetic.
Cluster Headache (Adjunctive)
Used alongside standard abortive and preventive therapies to reduce attack frequency during cluster periods. Inan et al. (2001) demonstrated efficacy in episodic cluster headache.
Post-Traumatic Headache
Persistent headache following head injury, particularly when the pain involves the occipital distribution. Common after whiplash mechanisms where cervical strain affects the C2 nerve roots.
Post-Concussion Headache
Headache persisting beyond the expected recovery window after concussion. When the occipital nerves are sensitized as part of the post-concussion syndrome, targeted block can break the pain cycle.
How It Fits Into Your Treatment Protocol
Occipital nerve block is rarely a standalone treatment. At The Neurogenesis Project, Dr. Orr integrates it into a broader protocol that addresses the mechanisms driving the headache rather than treating the symptom in isolation. For a patient with chronic migraine, the block may accompany chemodenervation with botulinum toxin and nutritional optimization. For post-traumatic headache, the block is often combined with IV nutrient therapy and neurocognitive rehabilitation.
The diagnostic value of the block shapes the treatment plan. When occipital nerve block provides substantial relief, it confirms that peripheral occipital nerve irritation is a meaningful contributor, and Dr. Orr can pursue that mechanism further with serial blocks, neuromodulation, or referral for occipital nerve stimulation in refractory cases. When the block provides only partial relief, it tells us that other pain generators — central sensitization, trigeminovascular activation, cervical facet pathology — require attention as well.
Blocks can be repeated every 4 to 6 weeks. Many patients find that as their broader treatment protocol takes hold, the interval between blocks lengthens and some patients eventually discontinue them entirely. This is the goal: use the block to manage acute pain while addressing the underlying pathophysiology through complementary treatments.

Frequently Asked Questions
What does the occipital nerve block procedure involve?+
Dr. Orr injects a small amount of local anesthetic at the base of the skull where the occipital nerves cross the bone. It takes about 10 to 15 minutes and most patients tolerate it well.
Read the full answer
The procedure takes approximately 10 to 15 minutes. After palpating anatomical landmarks at the occipital ridge, Dr. Orr injects a small volume of local anesthetic, typically bupivacaine, with or without a corticosteroid such as methylprednisolone, at the site where the greater occipital nerve crosses the superior nuchal line. The lesser occipital nerve is targeted approximately one-third of the distance from the greater occipital nerve toward the mastoid process. No imaging guidance is required. Most patients tolerate the procedure well with minimal discomfort.
How quickly does an occipital nerve block take effect?+
The numbing effect starts within 5 to 10 minutes. When a steroid is included, the anti-inflammatory benefit develops over 48 to 72 hours and can provide relief for several weeks to months.
Read the full answer
The local anesthetic component typically produces numbness in the posterior scalp within 5 to 10 minutes. Pain relief from the anesthetic lasts approximately 2 to 4 hours, but many patients experience a therapeutic benefit that extends days to weeks beyond the pharmacological duration of the drug. When a corticosteroid is included, the anti-inflammatory effect develops over 48 to 72 hours and can provide relief for several weeks to months.
How much does an occipital nerve block cost?+
It costs $175 per side. Most patients need both sides, totaling $350. This covers the procedure, medications, and monitoring.

An occipital nerve block at The Neurogenesis Project costs $175 per side. Most patients require bilateral injections, which totals $350. This fee covers the procedure, medications, and clinical monitoring. Dr. Orr discusses whether unilateral or bilateral injection is appropriate based on your headache pattern and examination findings.
How often can the procedure be repeated?+
Every 4 to 6 weeks as needed. Some patients find the intervals lengthen over time as the pain cycle is broken.
Read the full answer
Occipital nerve blocks can be repeated as needed, typically every 4 to 6 weeks. The interval depends on the duration of relief from prior injections and the underlying diagnosis. Some patients find that the interval between injections lengthens over time as the cycle of pain and muscle tension is interrupted. Dr. Orr monitors response to treatment and adjusts the schedule accordingly.
What conditions respond best to occipital nerve block?+
Occipital neuralgia responds best, but cervicogenic headache, migraine with pain in the back of the head, and post-traumatic headache also respond well.
Read the full answer
The strongest evidence supports occipital nerve block for occipital neuralgia, where the pain follows the distribution of the occipital nerves. Cervicogenic headache, migraine with occipital predominance, and post-traumatic headache also respond well in clinical practice. The block also serves a diagnostic function: if pain relief confirms occipital nerve involvement, it guides further treatment decisions, including whether to pursue longer-lasting interventions.
What are the risks and side effects?+
Side effects are generally mild: temporary numbness at the injection site, some tenderness, and occasionally lightheadedness. Serious complications are very rare.
Read the full answer
The procedure is well tolerated. Common side effects include temporary numbness at the injection site, mild tenderness, and occasionally lightheadedness. Rare risks include local infection, bleeding, and transient worsening of headache. When corticosteroids are used, there is a small risk of local skin changes at the injection site. Serious complications are exceedingly rare with landmark-based technique performed by an experienced clinician.
How long does the pain relief from an occipital nerve block typically last?+
Most patients get two to four weeks of relief from a single injection. Some achieve longer periods, especially when combined with other preventive treatments.
Read the full answer
Most patients experience relief lasting two to four weeks from a single injection. Some achieve longer periods, particularly when combined with other preventive treatments. The block also serves a diagnostic purpose: if it produces substantial relief, that confirms the occipital nerve as a contributor to the headache, which guides further treatment decisions.
Can I drive myself home after the procedure?+
Yes, in most cases. The procedure uses only local anesthetic and does not require sedation. You are observed for 15 to 20 minutes afterward.
Read the full answer
In most cases, yes. An occipital nerve block is performed with local anesthetic and does not require sedation. Patients are observed for 15 to 20 minutes afterward. If you tend to feel lightheaded with injections, arranging for a driver is a reasonable precaution.
