In short — Occipital neuralgia causes sharp, shock-like pain from the base of the skull and can be mistaken for migraine, but it comes from irritated nerves rather than the brain's pain-processing pathways. A focused exam and, when needed, a diagnostic nerve block — interpreted alongside the history and exam rather than on its own — can help point to the likely source and guide more targeted treatment.
A patient describes years of headaches labeled "migraine" that never quite fit the textbook description. The pain does not build slowly. It jolts, starting at the base of the skull and shooting toward the scalp, sometimes triggered by nothing more than brushing their hair.
Another patient in Jacksonville, Mandarin, or Orange Park has a headache that consistently follows neck stiffness after a long day at a desk or a fender-bender months earlier, and migraine medication has never touched it.
Both scenarios are common reasons for a pain-management evaluation, and both illustrate the same point: not every headache that starts at the back of the head is a migraine.
Two head-pain patterns that get mistaken for migraine
Occipital neuralgia is irritation or entrapment of the greater or lesser occipital nerves, which run from the upper neck up over the back of the scalp. When irritated, they can produce sudden, sharp, electric-shock-like pain distinct from the throbbing, pulsing quality more typical of migraine.
Cervicogenic headache is pain that is referred to the head from structures in the upper neck, often arthritic facet joints or irritated nerves at the top of the cervical spine. It frequently starts on one side, may worsen with certain neck movements or positions, and can be accompanied by neck stiffness.
Migraine, by contrast, is a neurological condition involving the brain's own pain-processing pathways. It often includes throbbing pain, sensitivity to light or sound, and sometimes nausea or visual aura, and it does not depend on ongoing nerve or joint irritation in the neck.
Why the mix-up happens so often
A common misconception is that any headache starting at the back of the head, or any headache that is severe and recurring, must be migraine. That is not always true. Occipital neuralgia and cervicogenic headache can mimic migraine closely enough that patients, and sometimes clinicians, treat them the same way for years before the pattern is reconsidered.
The distinction matters because migraine-specific medications are not designed to treat nerve irritation or joint-related referred pain, and a patient who has tried and failed several migraine therapies may actually have a different source, one that may call for a more targeted approach.
What this means for patients
If headache medication has never worked as well as it should, if the pain reliably starts at the base of the skull or worsens with neck movement, or if pressing on the back of the head reproduces the pain, it is reasonable to ask whether occipital neuralgia or cervicogenic headache should be part of the conversation.
This is not a suggestion to stop primary headache care. Many patients benefit from coordinated management between a neurologist or primary care physician and a pain-management evaluation focused on the neck and occipital nerves.
How the pattern is confirmed
Evaluation usually starts with a history and a focused exam, including checking whether pressing over the occipital nerves or moving the neck reproduces the familiar pain. Imaging of the neck may be reviewed if there is a history of injury or arthritis, though imaging alone does not diagnose occipital neuralgia or cervicogenic headache.
When the pattern remains unclear, a diagnostic occipital nerve block, an injection of numbing medication around the suspected nerve, can help confirm the source. Meaningful, even if temporary, relief after the block supports the diagnosis and helps plan next steps.
Treatment options, depending on the diagnosis
Care depends on which pattern fits, prior treatment, and the patient's goals. Options that may be considered, alone or in combination, include:
- Activity and posture modification, physical therapy, and medication review for muscular or joint-related neck contributions
- Occipital nerve blocks, which can serve as both diagnosis and treatment and may provide weeks to months of relief in patients who respond
- Radiofrequency ablation of the upper cervical facet nerves for confirmed cervicogenic headache after diagnostic blocks
- Peripheral nerve stimulation in selected patients with occipital neuralgia that has not improved enough with more conservative measures
None of these options is a guaranteed fix, and not every patient needs a procedure. The right plan depends on the diagnosis, exam findings, prior care, and what has and has not already been tried.
When headache needs urgent care
Most recurring headaches are not emergencies, but some warning signs deserve immediate attention. Seek emergency care for a sudden, severe "worst headache of your life," a headache with fever and stiff neck, or a headache accompanied by new weakness, numbness, confusion, vision loss, or trouble speaking. These can signal a serious underlying condition and should not wait for a scheduled visit.
The bottom line
Not every headache that starts at the back of the head, or that has resisted migraine treatment, is actually migraine. Occipital neuralgia and cervicogenic headache are two often-overlooked patterns that can be confirmed with a focused exam and, when needed, a diagnostic nerve block, opening the door to treatment options that migraine therapy alone does not address.
A careful evaluation can help sort out which pattern, or combination of patterns, best explains a patient's headaches and what the most reasonable next step should be.

Frequently Asked Questions
What is the difference between occipital neuralgia and a migraine?
Migraine is a neurological condition involving the brain's pain-processing pathways, often with throbbing pain, nausea, and light sensitivity. Occipital neuralgia comes from irritation of the occipital nerves at the base of the skull and tends to cause sharp, shooting, or electric-shock pain in a more specific location. The two can look similar and even occur together, which is why the pattern of pain matters.
What does occipital neuralgia feel like?
Patients often describe brief, stabbing or shock-like jolts of pain starting at the base of the skull and radiating toward the scalp, sometimes with tenderness when touching that area or brushing the hair. Between jolts, there may be a duller ache or scalp sensitivity, but the sharp shooting quality is the most distinctive feature.
How is occipital neuralgia or cervicogenic headache diagnosed?
Diagnosis starts with a history and physical exam, including pressing over the occipital nerves and assessing neck motion and tenderness. When the pattern is unclear, a diagnostic nerve block, an injection of numbing medication around the suspected nerve, can help confirm the source by temporarily relieving the pain.
What is an occipital nerve block, and how long does relief usually last?
An occipital nerve block is an injection of local anesthetic, often combined with a small amount of steroid, around the greater or lesser occipital nerve. It can serve as both a diagnostic test and a treatment, and relief may last anywhere from weeks to a few months in patients who respond, though results vary and repeat blocks are sometimes needed.
When is a headache a medical emergency?
Seek emergency care for a sudden, severe "worst headache of your life," a headache with fever and stiff neck, or a headache with new weakness, numbness, confusion, vision loss, or trouble speaking. These can signal a serious underlying condition and should not wait for a scheduled evaluation.
