Stellate Ganglion Block in La Porte, TX: Rapid Relief for PTSD, Anxiety, and Trauma
La Porte sits at the edge of Galveston Bay — a working waterfront city where petrochemical plants, industrial facilities, and the Port of Houston channel define the skyline and the workforce. If you live or work here, you know what occupational stress actually looks like: the incident response calls, the industrial emergencies, the years of high-stakes, high-exposure work that leaves residue on the nervous system long after the shift ends. Stellate ganglion block offers a direct biological intervention for that residue — a minimally invasive procedure that targets the sympathetic nerve cluster keeping your stress response locked in overdrive. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness, serving La Porte patients and those from Deer Park, Pasadena, Baytown, Webster, and southeast Harris County. Three Houston locations, open every day, 5am–9pm.
La Porte TX — Beyond the Shift
La Porte was there when Texas wrote its history. The Battle of San Jacinto was fought on its soil in 1836. Sylvan Beach has drawn families to Galveston Bay for over a century. Today, the city hosts one of the most concentrated industrial corridors in the nation — the Texas Ship Channel, refineries, chemical plants, and the infrastructure that keeps the region’s energy economy running. The people who work those facilities — operators, engineers, first responders, emergency crews — carry a particular kind of occupational exposure that doesn’t fully leave when they drive home.
Chronic occupational trauma rarely announces itself as PTSD. It shows up as difficulty sleeping through the night. A startle response that’s embarrassingly strong. A baseline tension that makes relaxation feel impossible. The inability to sit still in quiet environments that would have felt restorative before. The anger that arrives faster and louder than the situation warrants. These aren’t personality traits — they’re signatures of a sympathetic nervous system that’s been conditioned to stay ready, long past the point where readiness serves any useful purpose.
A 2023 case series published in the Journal of Personalized Medicine documented what happens when that overactivated state is addressed directly. Across 285 patients who received stellate ganglion block for anxiety associated with PTSD and trauma, GAD-7 scores measuring anxiety severity dropped by more than 50% — from a mean baseline of 15.9 (indicating severe anxiety) to well within the mild range at one-month follow-up. The researchers’ framing is precise: SGB works by “turning off the dysfunctional circuit” between the brain and the body, allowing the cervical sympathetic chain to reset itself. For La Porte patients whose anxiety has a clear occupational or trauma-driven character, that reset is directly available at Catalyst Health & Wellness.
What is Stellate Ganglion Block?
The stellate ganglion is a cluster of sympathetic nerves located at the base of the neck, formed by the fusion of the inferior cervical ganglion and the first thoracic ganglion — positioned just in front of the seventh cervical vertebra. As the primary sympathetic relay between the brain’s threat-detection circuitry and the upper body, it governs the speed and intensity of the fight-or-flight response. In healthy stress regulation, this system activates under threat and quiets when the threat passes. Under prolonged occupational or traumatic stress, the quieting mechanism fails — the stellate ganglion maintains elevated sympathetic outflow and keeps the body in a state of physiological readiness that no longer serves the situation.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
The mechanism behind SGB's effectiveness emerges directly from the physiology of how trauma rewires the autonomic nervous system — and why conventional treatments often can't fully reach that rewiring.
Resetting the Sympathetic Nervous System
Trauma — whether from a single overwhelming event or years of occupational exposure — drives the sympathetic nervous system into a pattern of chronic overactivation. The mechanism involves nerve growth factor (NGF): trauma triggers elevated NGF, which causes sympathetic nerve fibers to sprout and densify, increasing norepinephrine production and maintaining the amygdala in a state of persistent high alert. The stellate ganglion is the anatomical chokepoint where this dysregulation can be most precisely interrupted.
The 2023 Lynch et al. case series frames the mechanism clearly: SGB works by "turning off this dysfunctional circuit by temporarily numbing the cervical sympathetic chain" — disrupting the loop between brain and body and allowing it to "reset itself." This reset principle, they note, has been validated in pain medicine for decades: nerve blocks resetting nerve signals is an established clinical strategy, not a novel hypothesis. What's newer is its application to psychiatric conditions. For La Porte patients whose nervous systems have been conditioned by years of high-stakes occupational exposure, the reset SGB provides is precisely targeted to the biological substrate of what they're experiencing.
Reducing Brain Inflammation and Hyperactivity
Beyond the immediate sympathetic nervous system reset, SGB appears to produce lasting changes in how the amygdala — the brain's threat-detection center — processes incoming information. In PTSD and chronic anxiety, the amygdala is chronically hyperresponsive, treating neutral stimuli as threatening and maintaining a state of heightened reactivity that makes genuine relaxation impossible. Neuroimaging studies have documented measurable reductions in amygdala hyperactivity following SGB, correlating with the symptom improvements patients report.
The 2023 case series specifically tracked generalized anxiety disorder scores, capturing an aspect of SGB's effects beyond PTSD — recognizing that the same sympathetic dysregulation driving PTSD also drives the chronic anxiety that often accompanies occupational trauma without meeting the clinical threshold for a full PTSD diagnosis. The more than 50% reduction in anxiety scores confirms that SGB's amygdala-calming effects extend meaningfully into the anxiety spectrum.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step of the process at Catalyst has been built to be clear, supported, and genuinely safe for La Porte patients approaching trauma care for the first time or after other approaches haven't fully worked.
Step 1: Free Phone Consultation
No cost, no pressure. A clinical team member discusses your symptoms, treatment history, and what you’re looking for. You receive an honest assessment of whether SGB makes clinical sense — including if it doesn’t.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough pre-procedure evaluation: medical history, current medications, prior procedures, contraindications review. Every question you have is addressed before anything is scheduled.
Step 3: Day of Procedure
Budget two to three hours at the clinic. Arrange transportation — driving immediately after SGB isn’t advisable. Wear comfortable clothing with an accessible collar area. Eat normally unless instructed otherwise.
Step 4: The SGB Procedure
Dr. Ho positions you on a procedure table with your neck slightly extended. Real-time ultrasound imaging identifies the stellate ganglion and the anatomical structures surrounding it — blood vessels, nerves, and tissue planes that landmark techniques can’t visualize. Skin is numbed before the injection. The anesthetic is placed precisely near the stellate ganglion under continuous imaging guidance. The injection takes approximately 15–20 minutes. Warmth, slight hoarseness, or a sense of physical release are expected responses confirming the block is working.
Step 5: Recovery & Observation
You’re monitored for one to two hours. Temporary Horner syndrome effects — drooping eyelid, hoarse voice, warmth on the treated side — indicate successful stellate ganglion interruption and resolve within a few hours. Our team remains present throughout.
Step 6: Assessing Response & Follow-Up
Most patients notice changes within hours to days. Our team follows up to track response and recommend next steps: a second procedure two weeks later (standard protocol), maintenance scheduling, or complementary treatments at Catalyst.
The Science Behind Stellate Ganglion Block
A systematic review published in Chronic Stress examined 17 published studies on SGB for psychiatric disorders and found preliminary evidence supporting feasibility for treating conditions involving sympathetic nervous system dysregulation. Improvements were observed within 5 minutes of SGB and lasted one month or longer.
The 2020 randomized controlled trial in JAMA Psychiatry enrolled 113 active-duty military service members at three military hospitals. Two SGBs were administered two weeks apart. The SGB group achieved a mean PTSD symptom reduction of −12.6 points on the CAPS-5 versus −6.1 for sham — establishing Level 1B clinical evidence, the highest standard yet achieved for SGB.
A 2023 case series published in the Journal of Personalized Medicine enrolled 285 patients and tracked GAD-7 anxiety scores before SGB and at one week and one month post-procedure. The mean baseline score of 15.9 — indicating severe anxiety — declined significantly at both follow-up intervals. At one month, anxiety scores had dropped by more than 50%. The researchers described SGB as working by disrupting the “dysfunctional circuit” between the brain and the body, allowing the sympathetic system to reset — confirming that SGB’s benefits extend meaningfully to generalized anxiety, not only PTSD.
Key research findings:
- SGB reduced mean anxiety (GAD-7) scores by more than 50% in a 285-patient case series — from severe to mild range within one month
- The 2020 JAMA Psychiatry RCT established Level 1B evidence for SGB in PTSD — the strongest clinical evidentiary standard yet achieved for this procedure
- Effects appear within minutes to hours and last one month or longer, with growing evidence for multi-month durability
- 70–83% of treated patients achieve clinically significant positive outcomes across the published evidence base
Why Choose Catalyst Health & Wellness for Stellate Ganglion Block in La Porte
01
Led by Dr. Ho – Anesthesiology Expertise
SGB requires a physician with genuine procedural expertise in nerve blocks — not a peripheral skillset. Dr. Ho's board certification in anesthesiology places him among the small group of physicians whose training centers on exactly this: nerve block anatomy, ultrasound guidance, procedural precision, and the clinical management of anesthetic effects. For an industrial and occupational workforce that values competence above reassurance, Dr. Ho's credentials matter. His background as a former pediatrician adds a care culture that is patient-centered and genuinely attentive to comfort at every step.
02
Ultrasound-Guided Precision
Real-time ultrasound imaging is how Dr. Ho performs every SGB — visualizing the stellate ganglion and surrounding anatomy before placing the needle, not estimating from bony landmarks. The 2023 Lynch et al. case series specifically cites ultrasound as enabling SGB to be performed with the accuracy that maximizes both effectiveness and safety. This is the standard of care, and it’s the only approach used at Catalyst.
03
Whole-Person Approach
Occupational trauma often doesn’t arrive with a clean narrative — it’s accumulated, complicated by professional identity, and frequently entangled with concerns about how seeking care will be perceived. From the first phone call, our team engages with your full picture: what you’ve experienced, what you’ve tried, what daily life actually looks like, and what recovery would mean for you personally. Treatment plans reflect that full picture. What this means for you:
- Treatment shaped around your specific symptom profile and trauma history
- Active coordination with your existing therapist, psychiatrist, or VA provider if desired
- Guidance on combining SGB with other Catalyst treatments for stronger outcomes
- Ongoing clinical support that extends beyond the procedure itself
04
Extended Hours & Flexible Scheduling
Refineries, chemical plants, and port facilities don’t operate on 9-to-5 schedules — and neither do the people who work them. Our 5am to 9pm hours, Monday through Sunday at all three Houston locations, were specifically built for real schedules: pre-dawn appointments before day shifts, evening procedures after night turnover, weekend sessions that don’t require burning vacation time. If scheduling has been the reason care has been delayed, it isn’t anymore.
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.
