Sphenopalatine Ganglion Block in Energy Corridor: A Targeted Nerve Block for Migraine and Facial Pain
A minimally invasive, nonopioid procedure for stubborn head and face pain, delivered by Dr. Ho, a board-certified anesthesiologist. Serving the Energy Corridor from three Houston area locations, open daily from 5 am to 9 pm.
When Head and Face Pain Keep Coming Back
You already know the cycle. A migraine that wipes out an entire workday at your desk in the Energy Corridor. A cluster headache that hits on schedule and buckles your knees. A jolt of facial nerve pain triggered by nothing more than a gust of wind or a bite of lunch. You’ve tried the triptans, the daily preventives, maybe a nerve pain prescription, and the pain still finds its way home.
Sphenopalatine Ganglion Block, often shortened to SPG block, targets a nerve cluster tucked deep behind the nose that plays a central role in a lot of head and face pain. It’s a procedure many patients explore once standard headache and facial pain management hasn’t gone far enough. At Catalyst Health & Wellness, serving patients across the Energy Corridor, Dr. Ho performs the block in the office, with a full medical screening beforehand and observation afterward. Considered for head and face pain, it’s an off-label option, meant to work alongside the care you already receive from your neurologist or headache specialist, not to take its place. Every patient responds differently.

What Is an SPG Block, Exactly?
The sphenopalatine ganglion is a compact bundle of nerve cells resting deep behind your nose, inside a narrow space called the pterygopalatine fossa. It ranks as the largest nerve cell cluster in the head outside the brain, sitting at a busy junction of sensory and autonomic pathways connected to head and face pain.
An SPG block bathes that ganglion in local anesthetic to quiet the signals moving through it. The transnasal approach is the most common. Dr. Ho threads a thin, flexible catheter through the nostril and releases the anesthetic at the back of the nasal cavity, right beside the ganglion. There’s no facial needle with this method, and the whole procedure wraps up in only a few minutes.
What the research points to:
What Our Patients Say
The Mechanism Behind Sphenopalatine Ganglion Block
Think of the sphenopalatine ganglion as a switchboard for much of the feeling and involuntary activity across your face, sinuses, and forehead. In many headache and facial pain conditions, that switchboard stays stuck in an overactive state, driving the pain itself along with the stuffy nose, watery eyes, and facial pressure that so often tag along during a flare.
Quieting an Overworked Nerve Hub
By coating the ganglion with local anesthetic, an SPG block briefly interrupts the messages traveling through it. For some patients, calming that hub can help unwind a pain cycle that has become self-sustaining. Since the anesthetic sits directly on the ganglion, its effect stays concentrated on the pathways tied to head and face pain instead of spreading through the entire body.
Interrupting the Pain and Reflex Loop
The sphenopalatine ganglion carries fibers from the parasympathetic system, which is why so many headaches show up alongside a runny nose, teary eye, or pressure on one side of the face. Calming that loop may settle both parts together for some people. Responses differ from patient to patient, and the block is designed to support your current care plan and build on it, not stand in for it.
Head and Face Pain We Evaluate for SPG Block
We consider sphenopalatine ganglion block for Energy Corridor patients whose head or face pain hasn’t improved with first-line care. Whether it’s a fit depends on your diagnosis, history, and goals.
Chronic or Refractory Migraine
When migraines keep breaking through preventive and acute medications.
Cluster Headache
The condition with the strongest research support for SPG block.
Trigeminal Neuralgia and Facial Nerve Pain
Sharp, shocking facial pain that's hard to control.
Persistent Facial Pain
Ongoing facial pain without a clear structural cause.
Post-Traumatic Headache
Headache lingering after a head injury, an area still being studied.
Other Head and Face Pain
Where your physician believes a nerve block may be worth exploring.
If you're weighing this alongside other options for migraine or chronic pain, Dr. Ho can talk you through how a nerve block might fit in. For a deeper walkthrough of the full procedure, our detailed Houston area guide covers what to expect step by step.
Your Sphenopalatine Ganglion Block Journey at Catalyst Health & Wellness
Every step is clear, comfortable, and built around your needs. Here's what to expect.
Step 1: Free Phone Consultation
Your journey starts with a no cost, confidential phone call. It isn’t a sales pitch, just a real conversation about whether an SPG block makes sense for you. You’ll:
- Ask any questions about the procedure
- Share your headache or facial pain history and current symptoms
- Learn what a transnasal SPG block involves
- Get honest guidance on whether it fits your situation
There’s no charge and no obligation to continue.
Step 2: Medical Evaluation
If you decide to move forward, you’ll complete a medical evaluation so we can confirm the block is appropriate for you. This includes:
- Review of your diagnosis, medical history, and current medications
- A look at which headache or facial pain treatments you’ve already tried
- Any imaging or records your referring physician has shared
- A clear explanation of what to expect during and after the procedure
Step 3: Day of Procedure
Preparation is simple:
- No special fasting for most patients
- Wear comfortable clothing
- Arrange transportation if we advise it for your situation
- Plan for an easy rest of your day
Step 4: The Sphenopalatine Ganglion Block Procedure
The block itself takes just a few minutes, and you stay awake and alert the whole time.
- You recline comfortably while Dr. Ho positions a slim, soft catheter in the nostril
- He delivers the local anesthetic to the back of the nasal cavity, at the ganglion
- Most people find any discomfort mild
- You may notice a bitter taste, mild numbness at the back of the throat, or a little nasal drip
Those sensations are expected and pass on their own.
Step 5: Recovery and Observation
After the block, you’ll rest while we monitor you.
- We observe you for a short period afterward
- You take it easy for the remainder of the day
- Most people return to normal activity soon after
Step 6: Assessing Response and Follow-Up
Responses to SPG block vary widely from person to person. Some notice a change within the same day, others need a short series of visits.
- We’ll track how you respond
- Repeat blocks may be recommended based on your results
- Together we’ll decide whether and when to continue
Since everyone’s different, we personalize follow up around your individual response.
The Science Behind Sphenopalatine Ganglion Block
Interest in the sphenopalatine ganglion for head and face pain stretches back to 1908, and the approach has kept advancing since. An overview from Barrow Neurological Institute describes SPG block as a targeted way to reach the trigeminal pathways tied to headache and facial pain. Evidence points most strongly toward cluster headache, with encouraging findings in trigeminal neuralgia and migraine, and researchers note that larger controlled trials are still needed to firm up these findings.
A peer-reviewed study published through the National Institutes of Health examined a repeated nasal delivery approach to SPG block for chronic daily headache and found it generally well tolerated across a multi-week schedule, while the authors called for larger, controlled research to confirm the findings.
What the evidence shows:
- The longest history and steadiest support sits with cluster headache
- Encouraging findings exist for migraine and trigeminal neuralgia
- The procedure is minimally invasive, nonopioid, and repeatable
- Larger controlled trials are still called for across most uses
- Careful candidate selection and monitoring shape the results
That’s the honest state of the science: used for well over a century, encouraging, and still being refined through ongoing research. Part of your consultation is Dr. Ho walking you through how that research applies to your particular case.

Commonly Asked Questions
Get Help NowDoes a sphenopalatine ganglion block hurt?
Most people find it easy to tolerate. Because the common approach goes through the nostril instead of a needle into the face, any discomfort is usually mild. You might feel the catheter and notice a bitter taste as the anesthetic settles in.
How is an SPG block different from a stellate ganglion block?
They target different nerves for different problems. Stellate ganglion block goes to a bundle of nerves in the neck and is used for trauma and anxiety symptoms. Sphenopalatine ganglion block sits behind the nose and is used for head and face pain. Dr. Ho performs both.
How long does relief last?
It varies quite a bit from person to person, and some people need more than one visit. There’s no set timeline we can promise. We’ll track how you respond and plan any follow up around your results.
How many treatments will I need?
That depends on your condition and how you respond. Some people are managed with occasional single blocks, while others do better with a short series. Dr. Ho will recommend an approach based on your results.
Is the sphenopalatine ganglion block FDA approved for headaches?
The block is an established anesthetic procedure. Used for headache and facial pain, it’s an off label option and isn’t FDA approved for those specific conditions. We’ll always be straight with you about that.
Can I drive myself home?
For many patients the transnasal block doesn’t require sedation, but we’ll tell you at your evaluation whether to arrange a ride based on your specific plan. When in doubt, bring someone along.
Can an SPG block be combined with my current headache treatment?
Yes. It’s meant to work alongside the care you already have, not replace it. We’re glad to coordinate with your neurologist or headache specialist so everyone’s on the same page.
Will insurance cover a sphenopalatine ganglion block?
Coverage varies by plan and diagnosis. We can help check your benefits and go over payment options during your consultation.
