Stellate Ganglion Block in Bellaire, TX: Rapid Relief for PTSD, Anxiety, and Trauma
Catalyst Health & Wellness’s South Loop clinic sits inside Bellaire’s city limits — making SGB treatment genuinely walkable for some residents and a short drive for the rest. But proximity isn’t the only reason Bellaire residents are choosing stellate ganglion block. SGB addresses what years of therapy and medication often can’t: the sympathetic nervous system’s persistent overactivation that keeps PTSD and anxiety locked in place long after the triggering circumstances have changed. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness for Bellaire residents and patients from West University Place, Southside Place, Meyerland, Medical Center, and inner-loop Houston. Open every day, 5am–9pm.
Bellaire TX — Medically Savvy, Treatment Ready
Bellaire is compact by design. At 3.5 square miles, it’s one of the smallest incorporated cities in Texas — a tight-knit enclave of shaded streets, custom homes, and a community character that has held steady since the city’s incorporation in 1918. Bordered by the Texas Medical Center to the east and surrounded entirely by Houston, Bellaire draws an unusually high proportion of physicians, nurses, researchers, and healthcare executives who work at one of the world’s largest medical complexes and choose to live minutes from it.
That proximity shapes how Bellaire residents approach healthcare decisions. They tend to read the research. They ask clinical questions. They want the mechanism explained, not just the outcome. And when it comes to PTSD, anxiety, and trauma — conditions that frequently coexist with medical careers, caregiving roles, and the secondary trauma that accumulates in healthcare environments — they want treatment that reflects the same standard of evidence they apply in their professional lives.
Stellate ganglion block meets that standard. A 2025 case series published in the Scandinavian Journal of Pain — using a multidisciplinary team assessment that included a psychiatrist, clinical psychologist, and pain medicine physician — evaluated SGB in 36 patients with treatment-resistant mental health disorders ranging from PTSD to OCD, bipolar disorder, and substance use disorder. Across that diverse cohort, SGB was effective in 30 of 36 patients — an 83% success rate, consistent regardless of the specific diagnosis. The researchers attributed this breadth to a shared biological substrate: autonomic nervous system dysregulation with sympathetic dominance, which SGB directly addresses. For Bellaire’s medically sophisticated population, that mechanistic coherence is precisely the right kind of evidence.
What is Stellate Ganglion Block?
The stellate ganglion occupies a precisely defined anatomical location: where the inferior cervical ganglion and the first thoracic ganglion fuse at the base of the neck, just anterior to the seventh cervical vertebra. As a primary node in the sympathetic nervous system, it relays fight-or-flight signals from the brain’s threat centers — the amygdala, hypothalamus, and their downstream circuits — to the heart, lungs, and upper body. When trauma, chronic stress, or repeated difficult experiences push this system into a state of persistent dysregulation, the stellate ganglion continues signaling as if danger is present even when the environment has long since become safe.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
For a medically literate community like Bellaire, the mechanism deserves the full explanation — not a simplified version.
Resetting the Sympathetic Nervous System
The stellate ganglion sits at the center of a two-way neural highway between the brain's autonomic control centers and the body. In normal stress physiology, this highway activates during perceived threat and quiets through parasympathetic rebound when the threat passes. In PTSD and sustained anxiety, two disruptions maintain the overactivated state: first, elevated nerve growth factor (NGF) drives sympathetic nerve sprouting and increased norepinephrine production; second, the hypothalamic-pituitary-adrenal (HPA) axis maintains elevated cortisol, which in turn interacts with norepinephrine to consolidate and reinforce trauma-associated memories and threat-detection patterns.
SGB interrupts both pathways simultaneously. By temporarily blocking stellate ganglion nerve conduction, it reduces NGF and norepinephrine in the downstream sympathetic circuit. The 2025 Scandinavian Journal of Pain research team noted that "autonomic dysfunction with sympathetic dominance" is the shared neurobiological substrate across the diverse mental health disorders in their cohort — bipolar disorder, OCD, substance use disorder, PTSD, and health anxiety — explaining why a single anatomical intervention produced measurable improvement across all of them. The stellate ganglion, with its extensive connections to the hypothalamus, amygdala, infralimbic cortex, insula, and ventromedial prefrontal cortex, is a more central node in the emotional regulation network than its location in the neck suggests.
Reducing Brain Inflammation and Hyperactivity
Beyond the sympathetic reset, SGB produces downstream changes in the amygdala's threat-detection calibration. The amygdala receives sympathetic input via the stellate ganglion pathway; when that input is excessive and sustained, the amygdala becomes chronically hyperresponsive — treating neutral stimuli as threatening, maintaining intrusive re-experiencing, and driving the emotional reactivity that makes both daily functioning and therapeutic progress difficult. By reducing the sympathetic input sustaining this hyperresponsiveness, SGB creates a physiological window in which the amygdala can recalibrate — a window that neuroimaging studies have documented through measurable changes in amygdala activity following the procedure.
For many Bellaire patients — particularly those in healthcare roles who've found that insight-oriented therapy hasn't produced the bottom-up physiological change they need — this top-down effect that starts with the sympathetic nervous system and reaches the amygdala represents something fundamentally different from anything tried before.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step is designed for clarity, clinical rigor, and genuine patient agency — standards that Bellaire's medically informed population should expect.
Step 1: Free Phone Consultation
No charge, no obligation. A clinical team member discusses your full symptom picture, treatment history, and what you’re hoping to change. You receive an honest, evidence-based assessment of whether SGB is clinically appropriate — including if it isn’t.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough pre-procedure evaluation: complete medical history, current medications, contraindication review, and procedural discussion. Every question is addressed before any commitment is made.
Step 3: Day of Procedure
Budget two to three hours. Arrange transportation — post-procedure driving isn’t advisable. Comfortable clothing with accessible collar area. Normal eating unless specifically instructed otherwise.
Step 4: The SGB Procedure
Dr. Ho uses real-time ultrasound imaging to visualize the stellate ganglion and surrounding anatomical structures — blood vessels, nerves, tissue planes — before needle placement. The skin is numbed first. The anesthetic is delivered with precision under continuous imaging guidance. The injection takes approximately 15–20 minutes. Temporary Horner syndrome effects — slight drooping eyelid, hoarse voice, warmth on the treated side — are expected clinical signs confirming the block’s success.
Step 5: Recovery & Observation
One to two hours of monitored observation follows the procedure. Horner syndrome effects resolve within a few hours. Our team remains present throughout.
Step 6: Assessing Response & Follow-Up
Changes typically emerge within hours to days. Our team follows up to assess response and discuss next steps: a second procedure two weeks later, maintenance scheduling, or complementary treatment options within Catalyst’s South Loop location.
The Science Behind Stellate Ganglion Block
A systematic review in Chronic Stress examined 17 published studies on SGB for psychiatric disorders, finding preliminary evidence supporting feasibility for sympathetic nervous system dysregulation conditions. Improvements were observed within 5 minutes and lasted one month or longer.
The 2020 randomized controlled trial in JAMA Psychiatry enrolled 113 active-duty service members across three military hospitals. Two SGBs administered two weeks apart produced a mean PTSD symptom reduction of −12.6 points on the CAPS-5 versus −6.1 for sham — establishing Level 1B clinical evidence for SGB.
A 2025 case series published in the Scandinavian Journal of Pain by Niraj et al. evaluated SGB in 36 patients with treatment-resistant mental health disorders assessed by a multidisciplinary team. The cohort included PTSD, OCD with alcohol addiction, substance abuse disorder, bipolar disorder, and health anxiety. SGB was effective in 30 of 36 patients (83%). The researchers attributed this breadth to the common biological substrate — autonomic dysfunction with sympathetic dominance — shared across these conditions, and noted the stellate ganglion’s connections to the hypothalamus, amygdala, infralimbic cortex, insula, and ventromedial regions as the anatomical explanation for SGB’s wide-ranging effects.
Key research findings:
- SGB was effective in 83% of treatment-resistant mental health disorder patients across diverse diagnoses — not only PTSD — when assessed by a multidisciplinary team using validated outcome measures
- The 2020 JAMA Psychiatry RCT established Level 1B evidence: the highest clinical evidentiary standard yet achieved for SGB in PTSD
- The stellate ganglion’s neuronal connections to the hypothalamus, amygdala, infralimbic cortex, insula, and ventromedial regions explain why a single anatomical intervention produces broad psychiatric benefit
- Research continues expanding SGB’s evidence base, with ongoing trials exploring its use in MDD, borderline personality disorder, and post-cardiac arrest PTSD
Why Choose Catalyst Health & Wellness for Stellate Ganglion Block in Bellaire
01
Led by Dr. Ho – Anesthesiology Expertise
SGB requires a physician whose foundational training is built around nerve block anatomy, precision injection technique, and the physiological monitoring that administering a local anesthetic adjacent to major vascular structures demands. That description is anesthesiology training, not a peripheral qualification. Dr. Ho's board certification places him in the small group of physicians for whom these are core skills rather than add-ons. His former career as a pediatrician defines a clinic culture that is patient-centered, attentive, and unhurried — qualities that Bellaire's medically sophisticated residents recognize and expect.
02
Ultrasound-Guided Precision
Real-time ultrasound visualization of the stellate ganglion and surrounding anatomy is how every SGB at Catalyst is performed. For physicians and healthcare professionals in Bellaire who understand the difference between landmark-based and imaging-guided procedures, this isn’t a marketing point — it’s the clinical standard that matters for both accuracy and safety.
03
Whole-Person Approach
Bellaire patients — many of them healthcare professionals navigating the particular complexity of treating their own mental health — often arrive with a sophisticated understanding of their situation and a specific picture of what hasn’t worked. Our team engages with that complexity rather than simplifying past it. Treatment plans reflect the full clinical picture and are coordinated with existing psychiatric, psychological, and primary care providers. What this means:
- Treatment shaped around your specific diagnosis, symptom profile, and prior treatment history
- Active integration with your existing care team
- Clinical discussion of how SGB fits within a comprehensive approach — not as a replacement but as a complement
- Ongoing support extending well beyond the procedure itself
04
Extended Hours & Flexible Scheduling
Healthcare professionals don’t work 9-to-5. Rounds start at 6am. Procedures run until 9pm. Schedules rotate, change on call, and rarely create predictable weekday windows for personal appointments. Our 5am to 9pm hours, Monday through Sunday at all three Houston locations, were built for exactly that reality. Pre-dawn sessions before hospital arrival, evening appointments after discharge duties end, weekend procedures between weekend calls — all available.
05

Commonly Asked Questions
Get Help NowHow quickly does stellate ganglion block work?
Many patients notice improvement within days of the procedure, and some experience relief within minutes. Research shows that effects can appear within 5 minutes and last a month or longer. This rapid onset is one of SGB’s most remarkable features, especially for people who’ve been suffering with trauma symptoms for years.
Is stellate ganglion block safe?
Yes, SGB has been performed safely since the 1920s for various conditions. The procedure has a well-established safety profile with decades of clinical use. Common temporary effects include drooping eyelid, hoarse voice, and warmth on the treated side—all of which resolve within hours. Dr. Ho’s expertise as an anesthesiologist and use of ultrasound guidance ensures the highest safety standards.
Does the procedure hurt?
Most patients experience minimal discomfort. You’ll feel a small pinch from the initial numbing injection, followed by pressure as the medication is administered. The procedure itself takes only minutes, and most patients tolerate it very well. Dr. Ho’s gentle technique and experience help ensure your comfort.
How many SGB treatments will I need?
Many patients experience significant improvement after one or two treatments. Research protocols typically involve two SGBs administered two weeks apart. Some patients benefit from additional treatments over time. We’ll assess your response and recommend a treatment schedule based on your individual results.
How long do the effects last?
Effects typically last one month or longer, with some patients experiencing sustained improvement for many months. A 2025 study found that 96% of patients maintained significant improvement at 6-month follow-up. If symptoms return, the procedure can be repeated.
Can I combine SGB with other treatments?
Yes, many patients find that SGB works best as part of a comprehensive treatment approach. Combining SGB with ketamine therapy, for example, can provide both rapid sympathetic nervous system reset and enhanced neuroplasticity for processing trauma. SGB may also make traditional trauma therapy more tolerable and effective.
Do I need to talk about my trauma during treatment?
No. Unlike trauma-focused therapies that require detailed discussion of traumatic events, SGB works on the biological mechanisms underlying PTSD symptoms. You can share as much or as little as you’re comfortable with. The procedure addresses the physical hyperarousal component of trauma without requiring you to revisit painful memories.
Will insurance cover stellate ganglion block for PTSD?
Coverage varies by insurance plan. SGB for PTSD may be covered by some insurers, particularly when documented as treatment for a recognized condition with failed conventional treatments. We can help verify your benefits and discuss payment options during your consultation.
