An occipital nerve block is a small injection at the base of the skull, done sitting up, with no sedation. The needle part takes seconds. Most of the appointment is the conversation before it.
How do I prepare for an occipital nerve block?
We establish what we are treating and why, because the block is often diagnostic as well as therapeutic. Tell us where the pain starts, whether your scalp is tender to a hairbrush or a pillow, and whether neck position changes anything — those answers determine the target.
Bring your medication list. You do not need to fast, you do not need a driver, and you can eat normally beforehand.
How is an occipital nerve block done?
You sit leaning slightly forward. The landmarks are identified, the skin is cleaned, and we place the injection under ultrasound guidance — the occipital artery runs alongside the nerve, and ultrasound shows both so the needle can be steered around the vessel.
A small volume of local anesthetic goes in, sometimes with a corticosteroid depending on what we are treating. The needle is fine. Most people describe pressure and a brief sting.
What should I expect after an occipital nerve block?
- Numbness over the back of the head on the treated side. Expected, and it wears off over several hours.
- A heavy or odd-feeling scalp for the rest of the day.
- Occasional light-headedness for a few minutes — we will have you sit before you stand.
- Tenderness at the injection site for a day or two.
You walk out and drive yourself home. There is no recovery period and no sedation to sleep off. Most people go back to work.
What counts as a result
Two things happen on different timescales, and they mean different things.
The immediate effect — within minutes, while the anesthetic is working — is the diagnostic part. If the pain goes, that nerve was carrying it. If it does not, the pain is arising elsewhere and the diagnosis moves. See do nerve blocks for headache actually work.
The durable effect is the therapeutic part. Relief frequently outlasts the anesthetic by weeks — longer than the pharmacology alone explains, probably because interrupting the pain signal lets an irritated nerve settle. Duration varies widely between people.
How often can you get an occipital nerve block?
There is no fixed series of three. That number is a convention, not a clinical finding. We time the next block by how long the last one held and by what is happening clinically.
If a block gives four months of relief, we repeat it at four months. If it gives four days, repeating it is not the answer and we look again at the diagnosis.
What does an occipital nerve block treat?
The strongest fit is occipital neuralgia and cervicogenic headache. It is also used as a transitional treatment during a cluster bout, where a meta-analysis found 50% of patients pain-free at one month.1 In migraine the evidence is more mixed and the clearest indication is where there is a cervical or occipital contribution.
Common questions
Do I need someone to drive me?
No. There is no sedation, and you drive yourself home. See occipital nerve block.
Is the numbness afterwards normal?
Yes — numbness over the back of the head on the treated side is the expected result of anesthetizing that nerve, and it wears off over several hours. See occipital nerve block.
What if it wears off after a few days?
That is useful information. A short-lived response suggests the nerve is involved but is not the whole story, and we look at the upper cervical joints — see is your headache coming from your neck.
Can I have it during pregnancy?
It is sometimes appropriate, and the calculation differs from most headache drugs because the exposure is local and small. Tell us and we will discuss it — contact us.
Does an occipital nerve block hurt?
Most people describe pressure and a brief sting. The needle is fine, the injection is placed under ultrasound guidance, and the needle part takes seconds. There is no sedation because none is needed. You sit leaning slightly forward, and afterward we have you sit for a moment before you stand in case of brief light-headedness. See why image guidance matters.
How long does an occipital nerve block last?
The numbness over the back of the head wears off over several hours. The relief is a different matter: it frequently outlasts the anesthetic by weeks, and how long it holds varies widely from person to person. That duration sets the schedule. If a block gives four months of relief, we repeat it at four months. See how long an occipital nerve block lasts.
Does an occipital nerve block work right away?
The first effect comes within minutes, while the anesthetic is working, and it answers a diagnostic question. If the pain goes, that nerve was carrying it. If it does not, the pain is coming from somewhere else and the diagnosis moves. The lasting, therapeutic effect shows over the following weeks. See do nerve blocks for headache work.
How long does an occipital nerve block appointment take?
The injection itself takes seconds. Most of the appointment is the conversation before it, where we establish what we are treating and choose the target. There is no recovery period and no sedation to sleep off, so you walk out, drive yourself home, and most people go back to work. See occipital nerve block.
An occipital nerve block takes minutes, needs no sedation, and you drive yourself home. Read the occipital nerve block page, or book it as part of same-day headache care in St. Louis.
