When a headache keeps returning, it can feel as though the pain has taken control of your nervous system. Medication may help temporarily, but some people continue to experience headaches, migraines, neck pain, or scalp sensitivity despite trying standard treatments.
An occipital nerve block is a targeted procedure that may help reduce certain types of headache pain. Instead of treating the whole body, it places medication near nerves at the back of the head that carry pain and sensation signals.
So, how does an occipital nerve block work for headaches? In simple terms, it temporarily reduces pain messages traveling through the occipital nerves and into the nervous system. This may calm an active headache, decrease tenderness, or help identify whether the occipital nerves are contributing to the pain.
This guide explains how the procedure works, which headaches it may help, what the injection feels like, and when to speak with a headache specialist in Rochester, NY.
What Are the Occipital Nerves?
The occipital nerves are sensory nerves that travel from the upper neck into the scalp. They help carry sensation from the back, top, and sides of the head.
The three main occipital nerves are:
- The greater occipital nerve
- The lesser occipital nerve
- The third occipital nerve
The greater occipital nerve is the one most commonly targeted during an occipital nerve block. It begins near the upper cervical spine and travels through muscles and tissue at the back of the head before reaching the scalp.
When an occipital nerve becomes irritated, compressed, inflamed, or unusually sensitive, pain may begin at the base of the skull and travel upward. Some people feel the pain behind the ear, over the scalp, toward the forehead, or behind an eye.
However, pain does not need to stay directly over the nerve. The nervous system can interpret signals from an irritated occipital nerve as pain in another part of the head. This is known as referred pain.
How Does an Occipital Nerve Block Work for Headaches?
An occipital nerve block works by placing a small amount of medication near the targeted occipital nerve. The injection usually contains a local anesthetic that temporarily reduces the nerve’s ability to transmit pain signals.
Depending on the headache condition and the clinician’s treatment approach, a corticosteroid may sometimes be added to address inflammation. Steroids are not necessary for every occipital nerve block, and the medications used should be based on the patient’s diagnosis and medical history.
The treatment may help through several related effects.
1. It temporarily interrupts pain signals
The local anesthetic makes it more difficult for the targeted nerve to send pain messages. Patients may notice temporary numbness in part of the scalp as the medication begins working.
This does not destroy the nerve or permanently stop it from functioning. The anesthetic effect gradually wears off.
2. It reduces pain input reaching the brain
The occipital nerves connect with neurological pathways that also process pain from the head and face. When pain signals repeatedly enter these pathways, the nervous system may become more sensitive and reactive.
Reducing the incoming pain signals may temporarily calm this activity. This is one reason an injection near the back of the head can sometimes improve pain that spreads toward the side or front of the head.
3. It may calm irritation around the nerve
If tissue around the nerve is irritated, reducing local pain signaling may help settle tenderness and sensitivity. When a corticosteroid is included, it may also reduce inflammation around the treatment area.
4. It can provide diagnostic information
An occipital nerve block can be used for more than symptom relief. A clear improvement after the injection may suggest that an occipital nerve is involved in the patient’s pain pattern.
This does not always confirm a diagnosis by itself, but it can give the treating clinician useful information when building a longer-term plan.
How Are the Occipital Nerves Connected to Migraine?
Migraine is a neurological disorder involving more than a single nerve. It affects interconnected pain-processing pathways in the brain, brainstem, face, head, and neck.
The upper neck and occipital nerves communicate with an area known as the trigeminocervical complex. This region receives pain information from both the trigeminal nerve, which carries sensation from much of the face and head, and nerves from the upper cervical spine.
Because these signals meet within the same neurological network, pain that begins near the upper neck or occipital nerves can be experienced elsewhere in the head. It also helps explain why migraine and neck pain frequently occur together.
By reducing pain input from the occipital nerves, a nerve block may temporarily decrease activity within this connected headache pathway.
Which Headaches Can an Occipital Nerve Block Help?
Occipital nerve blocks may be considered for several headache and pain disorders. The treatment is not equally effective for every condition, and an accurate diagnosis matters.
Migraine
An occipital nerve block may be considered for episodic or chronic migraine, particularly when attacks are frequent, prolonged, difficult to control, or associated with significant pain at the back of the head.
It may be used to provide temporary relief, help interrupt a difficult migraine cycle, or support the patient while a preventive treatment begins working.
Occipital neuralgia
Occipital neuralgia occurs when an occipital nerve becomes irritated or injured. It often causes sharp, shooting, burning, or electric-like pain that begins near the base of the skull and travels upward.
The scalp may become tender, and activities such as brushing the hair, lying on a pillow, or turning the neck can sometimes trigger discomfort.
Because the pain directly follows the path of an occipital nerve, a nerve block may be used to reduce symptoms and help determine whether the nerve is the source of the pain.
Cervicogenic headache
A cervicogenic headache begins from a structure in the neck, even though the pain is felt in the head. It may be associated with restricted neck movement, muscle tension, joint dysfunction, or pain that worsens in certain positions.
An occipital nerve block may help selected patients, but neck-related headaches may also require treatment for the structural or muscular contributors to the pain.
Cluster headache
Cluster headache causes extremely severe pain, usually around one eye or one side of the head. Attacks occur in cycles or clusters and may include tearing, nasal congestion, eyelid changes, or restlessness.
Greater occipital nerve blocks are sometimes used as a transitional treatment for cluster headache while preventive treatment takes effect.
Post-traumatic head or neck pain
Injuries involving the head, neck, or upper cervical region may irritate nerves and surrounding tissues. An occipital nerve block may be considered when the pain pattern suggests involvement of an occipital nerve.
What Medication Is Used in an Occipital Nerve Block?
The primary medication is usually a local anesthetic. Common examples include lidocaine and bupivacaine.
These medications temporarily prevent the targeted nerve from transmitting signals normally. The scalp may feel numb for several hours after the procedure.
A corticosteroid may sometimes be included, particularly for selected headache conditions or when inflammation is suspected. However, adding a steroid does not necessarily provide better results for every migraine patient.
Your clinician should explain:
- Which medication will be used
- Whether a steroid will be included
- Why that medication was selected
- How long numbness may last
- What side effects to watch for
What Happens During the Procedure?
An occipital nerve block is generally performed in an outpatient medical setting. The injection itself usually takes only a few minutes, although the complete appointment may be longer because of the evaluation and monitoring involved.
Before the injection
Your clinician will review your headache pattern, medications, allergies, medical conditions, and past treatment response. It is important to mention blood-thinning medication, bleeding problems, infections, previous reactions to anesthetics, and any possibility of pregnancy.
Do not stop prescribed medication unless the clinician managing your care tells you to do so.
Locating the nerve
You may sit in a chair or lie in a position that gives the clinician access to the back of your head. The treatment area is examined for tenderness, and the nerve is located using anatomical landmarks. In some settings, ultrasound guidance may be used.
Placing the injection
The skin is cleaned before a small needle is inserted near the targeted nerve. The medication is then slowly administered.
The injection does not enter the brain or spinal cord. It is placed into the soft tissue near the nerve at the back of the head.
Checking the response
The clinician may ask whether the scalp feels numb and whether the headache changes. You may remain in the office briefly for observation before leaving.
What Does an Occipital Nerve Block Feel Like?
Most people remain awake throughout the procedure. General anesthesia is not usually required.
You may experience:
- A brief pinch when the needle enters the skin
- Pressure or stinging during the injection
- Temporary tenderness at the treatment site
- Warmth, tingling, or numbness in the scalp
- A temporary reproduction of your familiar head pain
The procedure may be uncomfortable, but it is typically brief. Tell the clinician if you feel unusually lightheaded, weak, short of breath, or unwell.
How Quickly Can It Start Working?
The local anesthetic may begin working within minutes. Some patients notice an early reduction in pain as the scalp becomes numb.
However, the response is not always immediate. Some people notice improvement over the following hours or days, while others receive little or no relief.
Immediate numbness confirms that the anesthetic reached the intended area, but it does not guarantee lasting improvement in the headache disorder.
How Long Does the Relief Last?
The duration of relief varies considerably. For some patients, improvement lasts only several hours or days. Others may experience reduced pain for several weeks or longer.
Results may depend on:
- The type of headache being treated
- Whether an occipital nerve is contributing to the pain
- The medication used
- Whether one or both sides are treated
- How frequently headaches occur
- Other treatments being used
- The patient’s individual nervous system response
An occipital nerve block is not considered a permanent cure. It is a targeted treatment that may provide a useful period of relief or help guide the next step in care.
Why Can Relief Last Longer Than the Numbing Medicine?
The anesthetic itself may numb the area for only a limited time, but some patients experience relief that lasts beyond the immediate medication effect.
This may happen because temporarily reducing pain signals can calm an overactive headache pathway. The nerve block may interrupt a cycle in which repeated pain input keeps the nervous system sensitized.
However, the exact response is difficult to predict. A longer benefit is possible, but it should not be guaranteed.
Can the Procedure Help Confirm the Cause of a Headache?
An occipital nerve block can sometimes serve as a diagnostic tool.
For example, a patient may have pain that begins at the base of the skull and spreads across the scalp. If that pain improves significantly after the nerve is blocked, it supports the possibility that the occipital nerve contributes to the symptoms.
The result must still be interpreted alongside:
- The location and quality of the pain
- Scalp tenderness
- Neck symptoms
- Migraine symptoms
- The neurological examination
- Other possible headache diagnoses
A response to the block is one piece of information, not a replacement for a complete headache evaluation.
What Are the Possible Side Effects?
Occipital nerve blocks are generally considered minimally invasive, but they still have possible side effects and complications.
Common temporary effects may include:
- Pain or soreness at the injection site
- Scalp numbness
- Bruising
- Minor swelling
- Dizziness or lightheadedness
- Temporary worsening of the headache
Less common risks may include:
- Bleeding
- Infection
- An allergic reaction
- Nerve injury
- Injury to a nearby blood vessel
- Temporary difficulty swallowing
When steroid medication is used, localized hair loss or skin thinning may occur in rare cases.
Contact your medical provider if you develop increasing redness, swelling, drainage, fever, persistent weakness, severe burning pain, difficulty swallowing, or other new symptoms after the procedure.
Who May Not Be a Candidate?
A nerve block may need to be postponed or avoided if you have:
- An infection near the planned injection site
- A known allergy to the proposed medication
- An uncontrolled bleeding disorder
- Certain blood-thinning medications that increase procedural risk
- A medical condition that makes the injection unsafe
- A headache pattern that requires urgent testing instead
Every patient should be evaluated individually. A treatment that is appropriate for one headache disorder may not be the right choice for another.
How Is a Nerve Block Different From Migraine Medication?
Oral and injectable migraine medications typically affect neurological pathways throughout the body. An occipital nerve block places medication near a specific nerve at the back of the head.
The two approaches may serve different purposes:
- Acute medication is used when a migraine attack begins.
- Preventive treatment aims to reduce future headache frequency or severity.
- An occipital nerve block may provide targeted, temporary relief.
- A nerve block may be used while a preventive treatment begins working.
- A nerve block may help identify whether occipital nerve pain is part of the problem.
Some patients receive a nerve block alongside medication and other therapies. It does not always replace the rest of the treatment plan.
Is an Occipital Nerve Block the Same as Botox?
No. They are different procedures.
An occipital nerve block places anesthetic near an occipital nerve to temporarily reduce pain signaling. Botox treatment for chronic migraine involves injections into multiple areas of the head and neck to reduce the release of chemicals involved in pain transmission.
Botox is generally used as a preventive treatment for qualifying patients with chronic migraine. An occipital nerve block may be used for several different headache conditions and may produce a faster, shorter-term response.
The more appropriate option depends on the diagnosis, headache frequency, symptoms, past treatments, and overall care plan.
What Should You Track After the Injection?
Keeping a headache diary can help determine whether the nerve block provided meaningful relief.
Track the following information:
- Your pain level before and after the procedure
- How quickly improvement began
- How long the benefit lasted
- The number of headache or migraine days
- Changes in neck pain or scalp sensitivity
- Use of rescue medication
- Nausea, light sensitivity, or sound sensitivity
- Your ability to work, sleep, exercise, and complete daily activities
- Any side effects
The goal is not only to determine whether the pain changed. It is also to understand whether treatment helped you function better.
Why the Correct Headache Diagnosis Matters
An occipital nerve block does not work for every headache because headaches do not all come from the same neurological pathway.
Pain near the back of the head can occur with:
- Migraine
- Occipital neuralgia
- Cervicogenic headache
- Tension-type headache
- Medication-overuse headache
- Post-traumatic headache
- Other neurological or structural conditions
These conditions can overlap, but their treatment plans may be different. A certified headache specialist can evaluate the full symptom pattern before deciding whether an occipital nerve block is appropriate.
Patients deciding where to seek care can also learn more about whether to see a migraine specialist or neurologist.
How Occipital Nerve Blocks Fit Into a Broader Treatment Plan
A nerve block may provide relief, but recurring headaches often require a broader plan.
Depending on the diagnosis, treatment may also include:
- Acute headache medication
- Preventive migraine treatment
- Trigger point injections
- Treatment for neck tension or restricted movement
- Osteopathic manual therapy
- Physical therapy or home exercises
- Sleep and stress support
- Medication-overuse prevention
- Neurologist-led neurostimulation options when appropriate
Navira Brain & Body offers neurologist-led headache and pain services in Rochester, NY. Care may combine headache medicine, nerve blocks, trigger point treatment, osteopathic manual therapy, and supportive neurological care based on the patient’s symptoms and diagnosis.
For patients who experience fatigue, poor concentration, or a post-migraine “hangover,” the evaluation may also consider whether brain fog and focus support should be part of the larger care plan.
When Does a Headache Need Urgent Care?
An occipital nerve block is not the appropriate first step when a headache includes warning signs of a potentially serious condition.
Seek emergency medical care for:
- A sudden, extremely severe headache
- A headache described as the worst of your life
- New weakness, numbness, confusion, or trouble speaking
- A seizure or loss of consciousness
- Fever with a stiff neck
- New vision loss
- A severe headache after a head injury
- A rapidly changing or unusual headache pattern
- A new severe headache during pregnancy or after delivery
New or unusual neurological symptoms should not be evaluated through an online article alone.
Frequently Asked Questions
Does an occipital nerve block stop all headache pain?
No. Some patients experience substantial relief, others notice partial improvement, and some receive no meaningful benefit. The response depends partly on the headache diagnosis and whether the occipital nerves contribute to the pain.
Does the injection go into the nerve?
The medication is generally placed into the tissue near the targeted nerve. The goal is to surround the nerve with anesthetic rather than intentionally inject medication directly into it.
Does an occipital nerve block go into the spine?
No. The injection is performed near the occipital nerve at the back of the head. It is not a spinal injection and does not enter the brain.
Can it help pain behind the eye?
It may help selected patients because occipital nerve signals connect with headache pathways that also receive sensation from the front of the head. Pain relief behind the eye is possible, but it depends on the cause of the headache.
Can both sides of the head be treated?
Yes. A clinician may perform the block on one side or both sides depending on the patient’s symptoms and headache pattern.
How often can occipital nerve blocks be repeated?
Repeat treatment depends on the medication used, how long relief lasts, the patient’s diagnosis, and the clinician’s assessment. There is no single schedule that is appropriate for everyone.
Can I return to normal activities afterward?
Many patients return to routine activities relatively quickly, but instructions vary. Ask your clinician about driving, exercise, bathing, work, and other activities after the procedure.
Is an occipital nerve block a non-drug treatment?
It is a targeted, minimally invasive procedure, but it still uses medication. The medication is injected near a specific nerve rather than taken orally or distributed throughout the body.
Occipital Nerve Blocks in Rochester, NY
Understanding how an occipital nerve block works is only the first step. The more important question is whether the procedure matches your specific headache pattern.
At Navira Brain & Body in Rochester, NY, Dr. Robert Myers provides neurologist-led care as a board-certified neurologist and UCNS-certified headache specialist. Evaluations consider where the headache begins, how it spreads, which symptoms occur with it, how often it happens, and what treatments have already been tried.
When appropriate, a personalized plan may include an occipital nerve block, trigger point injections, osteopathic manual therapy, headache medication management, neurostimulation, or other supportive options.
