Stellate Ganglion Block in Atascocita, TX: Rapid Relief for PTSD, Anxiety, and Trauma
Sleep used to come easily. Then it stopped. Not dramatically — just gradually, night by night, the rest getting shallower and the mornings getting harder, until a full night of sleep became something you remember having rather than something you do. That slow withdrawal of rest is one of the most common ways PTSD and chronic anxiety announce themselves — quietly, in the dark, long before the hypervigilance and reactivity become impossible to ignore. Stellate ganglion block addresses the biological mechanism driving that withdrawal: the sympathetic nerve cluster in your neck that’s maintaining an overactivated state your daily circumstances no longer require. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness, serving Atascocita residents and patients from Kingwood, Humble, Generation Park, Summerwood, and northeast Harris County. Three Houston locations open daily, 5am–9pm.
Atascocita TX — Beyond Treatment Stigma
Atascocita today bears little resemblance to the rural community it was forty years ago. Sprawling across the unincorporated northeast corner of Harris County along Lake Houston, it’s now one of the region’s most populous communities — family-oriented, well-resourced, served by an excellent school district, and home to a working population that ranges from oil and gas professionals to military families, first responders, teachers, and healthcare workers. The community here takes care of its own.
But the culture of taking care of your own can make PTSD and trauma harder to address. A 2024 review published in Neurorehabilitation — examining the full evidence base for SGB and trauma-informed care — noted that “over two-thirds of respondents agreed that a name change from PTSD to PTSI (‘Post Traumatic Stress Injury’) would reduce the stigma associated with the term.” More than half agreed the change would “increase their hope of finding a solution and their likelihood of seeking care.” The language matters because the stigma is real — particularly in communities where self-reliance is a cultural value and where the people most likely to be carrying trauma-related symptoms are also the least likely to ask for help.
Stellate ganglion block offers a pathway that sidesteps that stigma barrier. It frames trauma symptoms as what they are: a biological injury — an overactivated sympathetic nervous system, elevated nerve growth factor, elevated norepinephrine — rather than a psychological failing. It doesn’t require detailed trauma disclosure. It doesn’t require reliving anything. It works directly on the nervous system through a 15–20 minute procedure that many Atascocita patients describe as one of the least difficult clinical experiences they’ve had — and one of the most consequential.
What is Stellate Ganglion Block?
The stellate ganglion is a cluster of sympathetic nerves located at the base of the neck — the anatomical product of the inferior cervical and first thoracic ganglia fusing into a single relay node. It connects the brain’s central autonomic network to the sympathetic nerve supply of the upper body, governing the speed and intensity of the fight-or-flight response. In trauma-related conditions, this node becomes chronically overactive: maintaining elevated norepinephrine, keeping the amygdala hyperresponsive, and sustaining the physiological state of readiness that was adaptive during the traumatic experience and is now simply exhausting.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
For Atascocita patients who've done the therapy work and found a persistent physiological floor beneath which nothing can lower them, understanding what SGB does biologically — not just behaviorally — is the key to understanding why it can succeed where other approaches haven't.
Resetting the Sympathetic Nervous System
Trauma imprints itself on the autonomic nervous system through a biological cascade that the 2024 Neurorehabilitation review describes as "a potentially life-altering" physiological injury. The process begins with elevated nerve growth factor (NGF), which triggers sympathetic nerve sprouting — literally increasing the density of sympathetic nerve fibers — and drives up norepinephrine production throughout the system. Elevated norepinephrine keeps the amygdala hyperresponsive and maintains a state of sympathetic dominance that no amount of cognitive reappraisal or narrative processing can fully override from the top down.
SGB interrupts this cascade at its anatomical source. By temporarily blocking stellate ganglion nerve conduction, the anesthetic interrupts the sympathetic traffic sustaining the overactivated state — allowing NGF to normalize, norepinephrine to drop, and the amygdala to begin recalibrating toward a baseline the body hasn't accessed since before the trauma. The 2024 review specifically notes that SGB works best when combined with trauma-focused therapy — not as an alternative, but because lowering the biological floor makes what therapy offers clinically reachable in a way it wasn't before.
Reducing Brain Inflammation and Hyperactivity
Beyond the sympathetic nervous system reset, SGB produces measurable changes in how the amygdala processes incoming information. In sustained trauma-related dysregulation, the amygdala becomes chronically overresponsive — treating neutral stimuli as threats, maintaining intrusive memories, and fueling the emotional reactivity that makes daily functioning and therapeutic engagement difficult. Neuroimaging studies have documented reduced amygdala hyperactivity following SGB, correlating with the symptom improvements patients report.
The 2024 Neurorehabilitation review makes a point worth repeating: the average PCL score decrease in the largest real-world cohort studied was "nearly three times higher than the established 'clinically significant outcome'" threshold. That isn't a marginal effect. That's a categorical change in how the nervous system is functioning — the kind of change that opens space for relationships, sleep, productivity, and engagement with the life patients have built in communities like Atascocita.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step has been structured to be transparent, efficient, and genuinely respectful of what Atascocita patients need in order to actually follow through on care.
Step 1: Free Phone Consultation
No cost, no commitment. 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 for your situation — including if it doesn’t.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough evaluation before proceeding: medical history, medications, contraindications review, and a complete procedure discussion. Every question is addressed before anything is scheduled.
Step 3: Day of Procedure
Budget two to three hours. Arrange transportation — driving immediately after SGB isn’t advisable given temporary anesthetic effects. 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 identify the stellate ganglion and surrounding anatomy before placing the needle — visualizing blood vessels, nerves, and tissue planes that landmark techniques can’t see. 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 during the procedure are expected signs the block is working.
Step 5: Recovery & Observation
One to two hours of monitored recovery follows the procedure. Temporary Horner syndrome effects — drooping eyelid, hoarseness, warmth — 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 your response and recommend 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.
The 2024 review in Neurorehabilitation — authored by Springer, Whitmer, Steinlin, Gray, and Blankfield — synthesized the full international evidence base, including a 327-patient US cohort showing PCL decreases of 28.59 (men) and 29.2 (women) — nearly three times the established clinically significant threshold. It also cited an Australian multi-center civilian study across four cities (Sydney, Brisbane, Perth, Melbourne) showing statistically significant PCL improvement regardless of trauma type — converging evidence from a non-military population that broadens the clinical application of SGB beyond combat PTSD. The review specifically addresses how SGB combined with trauma-informed therapy optimizes outcomes, positioning the procedure as a biological foundation for psychological work rather than an alternative to it.
Key research findings:
- The 327-patient real-world US cohort showed PCL decreases nearly three times the threshold for clinical significance — a magnitude of change that goes beyond symptom management into genuine recovery territory
- The Australian multi-center civilian study confirmed statistically significant improvement “regardless of the type of trauma” — extending SGB’s evidence base to civilian, relational, and occupational trauma
- The 2020 JAMA Psychiatry RCT established Level 1B evidence — the highest standard yet achieved for SGB
- SGB combined with trauma-informed therapy produces stronger outcomes than either alone — the physiological floor SGB creates makes the therapeutic work reachable in ways it previously wasn’t
Why Choose Catalyst Health & Wellness for Stellate Ganglion Block in Atascocita
01
Led by Dr. Ho – Anesthesiology Expertise
SGB is an interventional procedure requiring nerve block anatomy expertise, ultrasound guidance training, and the clinical judgment to manage local anesthetic delivery adjacent to major vascular structures. Dr. Ho's board certification in anesthesiology places him precisely among the physicians whose core training covers these skills. His former career as a pediatrician ensures that procedural precision is paired with a patient-centered care culture — unhurried, attentive, and genuinely present throughout the experience.
02
Ultrasound-Guided Precision
Every SGB at Catalyst uses real-time ultrasound imaging — visualizing the stellate ganglion and surrounding structures before needle placement, not estimating from anatomical landmarks. This is the current standard of care for SGB, and it’s the only approach Dr. Ho uses. For Atascocita patients accustomed to working with professionals who do their job correctly rather than approximately, this matters.
03
Whole-Person Approach
The 2024 Neurorehabilitation review positions SGB specifically as part of a comprehensive trauma care approach — biological foundation plus therapeutic support. Our team engages with your full clinical picture: symptoms, prior treatment history, what’s worked and what hasn’t, and how SGB fits within your overall care. Treatment plans are built around that full picture and updated as you respond. We coordinate with your existing therapist, psychiatrist, or VA provider rather than operating as a separate track. What this means:
- Treatment tailored to your specific trauma history and symptom profile
- Active integration with your existing care team
- Guidance on how SGB positions you for stronger outcomes from subsequent therapy
- Ongoing clinical support extending beyond the procedure itself

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.
