A 2024 comprehensive review found SGB efficacy for PTSD symptoms ranges from 70–83% of treated patients achieving clinically significant positive outcomes across the full range of existing studies
Stellate Ganglion Block in Lazybrook, Houston TX: Rapid Relief for PTSD, Anxiety, and Trauma
Named for the lazy winding of White Oak Bayou along its eastern edge, Lazybrook is one of Houston’s most genuinely intimate neighborhoods — 1,246 residents, a civic club that has been organizing National Night Out and community events for decades, deed-restricted ranch homes built in the 1950s and 1960s on lots larger than almost anything else inside the 610 Loop, and a wooded setting along the bayou that makes it feel miles from the city it’s actually embedded in. People who live here chose it deliberately — for the trails, the Lorraine Cherry Nature Preserve, Jaycee Park’s disc golf and dog park, and the kind of neighbor who actually knows your name. When PTSD, anxiety, or trauma disrupts the capacity to be fully present in exactly that kind of community, stellate ganglion block reaches the biological mechanism maintaining that disruption. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness, with the Heights clinic at 104 W. 12th Street minutes from Lazybrook via TC Jester. Three Houston locations, open 5am–9pm, seven days a week.
Lazybrook Treatment Backed Internationally
Lazybrook’s residents include professionals in medicine, law, academia, and research — people who track evidence in their fields and apply the same analytical lens to their personal health decisions. The SGB evidence base has now reached the international academic mainstream through a channel that matters for that population.
A 2025 systematic assessment published in European Psychiatry — the journal of the European Psychiatric Association and published by Cambridge University Press — reviewed the full body of clinical evidence for stellate ganglion block in PTSD. The authors, drawn from BronxCare Health System, Riga Stradins University in Latvia, Case Western Reserve University in Cleveland, and the University of Arkansas for Medical Sciences, concluded that SGB “acts by blocking sympathetic outflow, offering promise in alleviating autonomic dysfunction associated with PTSD symptoms.” European Psychiatry is not a fringe publication — it’s the flagship journal of the European Psychiatric Association, subjected to full peer review through Cambridge University Press. When an international, multi-institutional academic team publishes a systematic assessment in that venue, it reflects that SGB has crossed from emerging treatment to credible clinical discussion in the international psychiatric mainstream.
For Lazybrook residents who apply evidence standards to their professional lives, that trajectory — from military case series to JAMA Psychiatry RCT to European Psychiatric Association systematic assessment — represents the kind of scientific momentum worth taking seriously.

What is Stellate Ganglion Block?
The stellate ganglion — the sympathetic nerve cluster formed by the fusion of the inferior cervical and first thoracic ganglia at the base of the neck — is the primary relay node connecting the brain’s central autonomic network to the sympathetic nerve supply of the head, neck, upper body, and cardiovascular system. In PTSD and anxiety, trauma elevates nerve growth factor, drives sympathetic nerve sprouting, sustains elevated norepinephrine, and maintains the amygdala in a state of chronic hyperarousal.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
Understanding SGB's mechanism contextualizes why the international academic community has reached the conclusions reflected in the 2025 European Psychiatry systematic assessment.
Resetting the Sympathetic Nervous System
The autonomic dysfunction that European Psychiatry's systematic assessment identifies as SGB's clinical target develops through a well-documented biological cascade: trauma triggers elevated nerve growth factor, which drives sympathetic nerve sprouting and increased fiber density, which sustains elevated norepinephrine production, which maintains the amygdala in a state of chronic hyperresponsiveness. In a neighborhood like Lazybrook — where environmental safety is genuine, community connection is available, and the bayou trails invite the kind of relaxed presence that benefits mental health — the gap between the objective environment and the internal physiological state is the defining feature of untreated PTSD. The environment offers safety. The autonomic nervous system refuses to register it.
SGB interrupts the cascade at the stellate ganglion — the anatomical relay node through which the brain's sympathetic overactivation is maintained. By temporarily blocking stellate ganglion nerve conduction, the local anesthetic allows the NGF cascade to normalize, norepinephrine to drop, and the amygdala to recalibrate. That recalibration is what produces the physical sense of release that many Lazybrook patients report during the procedure itself — and the measurable symptom improvements that follow across the days and weeks after it.
Reducing Brain Inflammation and Hyperactivity
Beyond the immediate sympathetic reset, SGB produces measurable downstream changes in amygdala function. Neuroimaging research — cited in the European Psychiatric Association's review context — documented measurable changes in amygdala activity following SGB, with the right amygdala and hippocampal areas showing reduced overactivation that correlated with patient-reported symptom improvement. The amygdala in PTSD treats neutral stimuli as threats — a bark from a neighbor's dog, a sudden noise on the bayou trail, an unexpected knock at the door — not because those stimuli are actually threatening, but because the amygdala's calibration is stuck in a threat-readiness state it can't exit without biological intervention.
For Lazybrook residents who've built a genuinely safe, community-oriented life and still find themselves unable to rest in it, this amygdala recalibration is the clinical event that makes the environment's actual safety finally accessible.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step is designed for clarity, clinical precision, and genuine accessibility for Lazybrook patients minutes from the Heights clinic.
Step 1: Free Phone Consultation
No cost, no commitment. A clinical team member discusses your full history — symptoms, prior treatments, what daily life looks like — and gives you an honest clinical assessment of whether SGB is appropriate.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough pre-procedure evaluation: medical history, current medications, prior procedures, and contraindication review. Every question is addressed before any commitment is made.
Step 3: Day of Procedure
Budget two to three hours at the clinic. Arrange transportation — post-procedure driving isn’t advisable. Comfortable clothing with accessible collar area. Normal eating unless instructed otherwise.
Step 4: The SGB Procedure
Dr. Ho uses real-time ultrasound imaging to visualize the stellate ganglion and surrounding anatomy before needle placement — blood vessels, nerves, and tissue planes identified before the needle is introduced. Skin is numbed first. The anesthetic is delivered under continuous imaging guidance. The injection takes approximately 15–20 minutes. Warmth, slight hoarseness, or a sense of physical release confirm the block is working.
Step 5: Recovery & Observation
One to two hours of monitored recovery follows. Temporary Horner syndrome effects — drooping eyelid, hoarseness, warmth on the treated side — indicate successful stellate ganglion interruption and resolve within hours. Our team remains present throughout.
Step 6: Assessing Response & Follow-Up
Changes typically emerge within hours to days. Our team follows up to track response and determine next steps: a second procedure two weeks later, maintenance scheduling, or complementary treatment options at Catalyst.
The Science Behind Stellate Ganglion Block
A systematic review published in Chronic Stress examined 17 published studies on SGB for psychiatric disorders, finding preliminary evidence supporting feasibility for treating 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 two weeks apart produced a mean PTSD symptom reduction of −12.6 points versus −6.1 for sham — establishing Level 1B clinical evidence for SGB.
The 2025 systematic assessment published in European Psychiatry — the flagship journal of the European Psychiatric Association, published by Cambridge University Press — reviewed the complete body of SGB evidence for PTSD from an international multi-institutional perspective. Authors drawn from BronxCare Health System (New York), Riga Stradins University (Latvia), Case Western Reserve University (Ohio), and the University of Arkansas for Medical Sciences evaluated SGB’s mechanism, safety profile, and clinical utility. Their conclusion: SGB “acts by blocking sympathetic outflow, offering promise in alleviating autonomic dysfunction associated with PTSD symptoms.” Publication in European Psychiatry reflects peer-review from the international psychiatric academic community — a meaningful evidence threshold for patients and clinicians who track the field’s evolution across geographic and institutional lines.
Key research findings:
- The 2025 European Psychiatry systematic assessment represents the international academic community’s current evaluation of SGB for PTSD — published in the European Psychiatric Association’s flagship Cambridge University Press journal
- The 2020 JAMA Psychiatry RCT established Level 1B evidence — the highest clinical standard yet achieved for SGB
- 70–83% of treated patients achieve clinically significant positive outcomes; standard PTSD treatment achieves remission in 30–40%
- Effects appear within minutes to hours and typically last one month or longer

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.
