Occipital Nerve Block

An occipital nerve block is used to diagnose and treat occipital neuralgia — sharp, shooting pain at the base of the skull and over the back of the head — and to help some people with migraine, cluster headache or headaches that start in the neck^[1]. It places numbing medicine, sometimes with a steroid, next to the greater occipital nerve. If your usual pain fades while the nerve is numb, the nerve is likely involved, which helps guide the next step in your care.

Common causes include occipital neuralgia, tight or tender neck muscles, migraine, and cervicogenic headache, which starts in the joints and nerves of the upper neck^[2][12]. Occipital neuralgia tends to feel sharp, shooting or electric, often on one side, while muscle and joint pain is more of a steady ache. A careful exam helps tell these apart. When the upper neck joints are suspected, a cervical medial branch block may be the better test.

The injection is given at the back of the head, just above the hairline and a little to one side of the center of the skull base, where the greater occipital nerve comes up through the neck muscles into the scalp. The lesser occipital nerve, a bit closer to the ear, may be blocked as well. One or both sides can be treated, depending on where your pain is^[10].

Most people feel a quick pinch and a few seconds of pressure or stinging as the medicine goes in, followed by numbness of the scalp. The needle is very fine and the injection takes only a few minutes^[12]. Sedation is rarely needed for this kind of injection^[10]. The area can be sore for a day or two afterward, and ice or an over-the-counter pain reliever usually helps.

When it works, the numbing medicine usually eases pain within 20 to 30 minutes, and relief can last from several hours to several months^[1]. If a steroid is included, it may take 48 to 72 hours to add its effect^[9]. Because the response is hard to predict, a headache diary for the following weeks helps you and your physician judge the result.

It can help some people with migraine, especially chronic migraine, but it is not a stand-alone treatment. Meta-analyses found fewer headache days and lower intensity during the first one to two months compared with placebo, although the studies were small and the evidence quality is low^[6][7]. Adding a steroid did not seem to improve migraine results^[7]. Blocks work best alongside preventive care such as the options on our chronic migraine page.

It depends on your diagnosis and how you respond. The New York workers’ compensation guidelines allow one to three injections when each produces progressive improvement^[9], and Medicare in New York allows up to four in 12 months for occipital neuralgia^[10]. If you need more than three blocks within six months, it is generally time to explore other options^[1]. Limiting repeat steroid doses also lowers the chance of skin thinning or hair loss at the site.

Most people return to normal activities the same day. Rest a few minutes before leaving, because brief unsteadiness is common in the first half hour^[9]. Bring a driver for your first block, and do not drive at all if you had sedation. Use ice for soreness, record your headaches in a diary, and call us for fever, spreading redness, a severe new headache or weakness.

Usually not. Peripheral nerve blocks, including occipital nerve blocks, are classed as low bleeding-risk procedures in interventional pain guidelines^[11], and the American Headache Society’s consensus lists blood-thinner use as a situation that calls for extra care during the injection^[4]. Never stop a blood thinner on your own — we will coordinate with the doctor who prescribed it if any change is needed.

Serious problems are rare. Common effects include soreness at the site, scalp numbness, and brief dizziness or light-headedness; some people faint during the injection^[12]. A steroid can cause a small patch of hair loss or skin thinning. Rare risks include infection, bleeding, nerve injury and medicine entering the nearby occipital artery, which can cause toxicity or, very rarely, a seizure^[9].

Often, when coverage rules are met. Under Medicare’s local policy for New York, effective October 25, 2026, occipital nerve blocks are covered for occipital neuralgia after a positive diagnostic block and documented failure of medical treatment, up to four a year; Medicare treats their use for other headache types as investigational^[10]. Commercial plans often require prior authorization. New York workers’ compensation recommends the block for occipital neuralgia^[9], and no-fault claims follow their own rules. We verify your benefits first.

A block that does not help is still useful: it suggests the occipital nerve is not the main source of your pain. Your physician may test the upper neck joints with a medial branch block, adjust migraine prevention through chronic migraine treatment, try trigger point injections for tight muscles, or discuss peripheral nerve stimulation. Medicare currently considers radiofrequency ablation of the occipital nerves investigational^[10].
