Stellate Ganglion Block in Deer Park, TX: Rapid Relief for PTSD, Anxiety, and Trauma
You don’t talk about it at work. You don’t bring it home if you can help it. The shift ends, the gate closes behind you, and you’re supposed to leave it there — but the nervous system doesn’t clock out on schedule. What you’ve absorbed over years of working a refinery, responding to industrial emergencies, or carrying combat home doesn’t dissolve at the city limits. It stays in the body, in the chronic tension that doesn’t release, in the sleep that stops being restful, in the reactions that don’t match the situation. Stellate ganglion block is a biological intervention for exactly that kind of accumulated load — targeting the sympathetic nerve cluster at the base of the neck that’s maintaining your stress response in a state your daily life no longer requires. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness for Deer Park residents and patients from Pasadena, La Porte, Baytown, Channelview, and southeast Houston. Three locations, open every day, 5am–9pm.
Deer Park TX — Grit Meets Science
Deer Park has been an industrial city since before it was fully incorporated — home to oil refineries, chemical plants, and the Ship Channel infrastructure that keeps the Houston economy moving. Shell, INEOS, and LyondellBasell are neighbors. The fire department runs on calls that most departments never see. The people who live here tend to work hard, fix things themselves, and not ask for more than they need.
That ethos serves this community well in almost every domain. When it comes to trauma and stress-related conditions, it’s the exact culture that allows symptoms to accumulate unchallenged. Hypervigilance passes for alertness. Sleep disruption is attributed to shift work. Emotional reactivity is chalked up to stress. Years go by before the pattern becomes undeniable — and by then, the sympathetic nervous system has been running overactivated for so long that conventional interventions can only chip at the edges.
A 2025 randomized controlled trial published in Frontiers in Neurology — one of the most rigorous SGB studies specifically focused on anxiety and sleep disruption — enrolled 128 patients with generalized anxiety disorder and sleep disturbance and found that SGB produced significant improvements not only in anxiety scores but also in objective sleep quality measures, including total sleep time and sleep efficiency. Critically, the researchers measured neurochemical changes: SGB produced measurable reductions in norepinephrine — the primary stress hormone driving sympathetic overactivation — alongside increases in serotonin and neuropeptide-Y, both associated with relaxation and mood stabilization. That’s not a subjective effect. That’s the overactivated system actually changing its chemistry.
What is Stellate Ganglion Block?
The stellate ganglion is a cluster of sympathetic nerves at the base of the neck, formed by the fusion of the inferior cervical and first thoracic ganglia, positioned just anterior to the seventh cervical vertebra. It’s a relay node — the anatomical junction where the brain’s central threat-detection circuitry connects to the sympathetic nerve supply of the head, upper body, and cardiovascular system. When trauma or sustained occupational stress drives this node into chronic overactivation, it maintains elevated norepinephrine, keeps the amygdala hyperresponsive, and sustains a physiological state of readiness that was once adaptive and is now simply exhausting.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
For Deer Park patients who've been through enough to want straight answers rather than soft framing, here's the honest mechanism:
Resetting the Sympathetic Nervous System
Chronic occupational and trauma-related stress drives the sympathetic nervous system into a self-sustaining pattern of overactivation. The core mechanism involves nerve growth factor (NGF): sustained stress triggers elevated NGF, which causes sympathetic nerve fibers to sprout and densify, driving up norepinephrine production throughout the system. The 2025 Frontiers in Neurology RCT measured this directly — SGB produced a reduction in circulating norepinephrine alongside increases in serotonin and neuropeptide-Y, confirming that the procedure changes the neurochemical environment maintaining anxiety and sleep disruption, not just the symptoms those neurochemicals produce.
By temporarily blocking stellate ganglion nerve conduction, SGB interrupts the sympathetic signal sustaining this overactivated state. The researchers described the stellate ganglion as a "key node of the cervical sympathetic chain" playing "a critical role in regulating autonomic balance, stress responses, and circadian rhythms" — explaining why a single anatomical intervention produces improvements across anxiety, sleep, and emotional reactivity simultaneously. It's not addressing three separate problems. It's addressing one overactivated system that was driving all three.
Reducing Brain Inflammation and Hyperactivity
Beyond the immediate sympathetic reset, SGB produces downstream effects on amygdala function and the locus coeruleus-amygdala pathway that is "critically involved in fear memory consolidation and hyperarousal responses." In PTSD and sustained anxiety, the amygdala remains chronically hyperresponsive — treating neutral stimuli as threats, maintaining vigilance past appropriate windows, and fueling the emotional reactivity that makes workplace safety cultures and home life difficult to fully inhabit simultaneously.
The 2025 Frontiers in Neurology study also noted that SGB modulates "interactions among the cerebral cortex, brainstem ascending reticular inhibitory system, and hypothalamic-cortical pathways" — creating physiological conditions for longer total sleep duration and improved sleep efficiency. For Deer Park workers whose sleep disruption has been attributed to shift work and chalked up as an occupational reality, this finding establishes that the overactivated sympathetic system is a direct contributor to poor sleep — and that addressing it at the stellate ganglion can restore restorative sleep in a way that sleep medications typically don't, without the risks of dependency those medications carry.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step is built to be efficient, honest, and respectful of Deer Park patients' time and no-nonsense expectations.
Step 1: Free Phone Consultation
No cost, no sales pitch. A clinical team member discusses your symptoms, treatment history, and what you’re hoping to change. You receive an honest clinical assessment — including if SGB isn’t the right fit for your situation.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough evaluation before proceeding: medical history, current medications, prior procedures, and contraindication review. Every question is addressed before anything is scheduled.
Step 3: Day of Procedure
Budget two to three hours. Arrange transportation — post-procedure driving isn’t advisable. Comfortable clothing with accessible collar. 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 placing the needle. Skin is numbed first. The anesthetic is delivered with precision under continuous imaging guidance. The injection takes approximately 15–20 minutes. Warmth, slight hoarseness, or a sense of physical release during the procedure are expected signs confirming 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 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 track your 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 military service members across three military hospitals. Two SGBs administered 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 highest standard yet achieved for this indication.
The 2025 double-blind randomized controlled trial published in Frontiers in Neurology enrolled 128 patients with generalized anxiety disorder and sleep disturbance — specifically excluding patients with comorbid depression to isolate anxiety and sleep as primary outcomes. The SGB group demonstrated significant improvements over the control group in anxiety scores (Hamilton Anxiety Scale and GAD-7), objective sleep quality measures (Pittsburgh Sleep Quality Index, total sleep time, sleep efficiency), and neurochemical markers: norepinephrine decreased and both serotonin and neuropeptide-Y increased, confirming that SGB’s benefit reflects genuine neurochemical recalibration rather than placebo effect.
Key research findings:
- The 2025 Frontiers in Neurology RCT documented measurable reductions in norepinephrine and increases in serotonin and neuropeptide-Y following SGB — the first double-blind RCT to confirm neurochemical changes alongside behavioral improvements in anxiety and sleep quality
- The 2020 JAMA Psychiatry RCT established Level 1B evidence — the highest clinical standard yet achieved for SGB
- Effects appear within minutes to hours and last one month or longer, with the 2025 Uniformed Services University retrospective study confirming 96% improvement at six-month follow-up
- 70–83% of treated patients achieve clinically significant positive outcomes across the full published evidence base
Why Choose Catalyst Health & Wellness for Stellate Ganglion Block in Deer Park
01
Led by Dr. Ho – Anesthesiology Expertise
SGB is a procedural intervention that requires nerve block anatomy expertise, ultrasound guidance proficiency, and the clinical judgment to manage anesthetic delivery in a complex anatomical region. Dr. Ho's board certification in anesthesiology places him precisely in that group. In an industrial community that knows the difference between someone who's done a job before and someone who learned it from a manual, that credential matters. His former career as a pediatrician ensures the precision is paired with genuine attentiveness to patient experience.
02
Ultrasound-Guided Precision
The 2025 Frontiers in Neurology RCT used “ultrasound-guided SGB” as the standard — direct visualization of the target structure and surrounding anatomy, not landmark estimation. Every SGB at Catalyst uses real-time ultrasound imaging. The procedure is done correctly or not at all.
03
Whole-Person Approach
Industrial and occupational trauma often arrives without a clean narrative and without a clinical label — it’s the accumulated weight of years doing a job that asks a lot.

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.
