Stellate Ganglion Block in Richmond, TX: Rapid Relief for PTSD, Anxiety, and Trauma
Richmond is one of Texas’s oldest incorporated cities — founded on the Brazos River in 1837 under the Republic of Texas, home to Texas legends Jane Long and Deaf Smith, and still serving as the seat of Fort Bend County while master-planned communities like Pecan Grove, Harvest Green, and Long Meadow Farms grow rapidly in its orbit. It’s a city with deep roots and a rapidly expanding population of young families who have brought new energy to the Fort Bend corridor. Within those households — veterans, first responders, new parents, healthcare workers, agricultural workers — PTSD and chronic anxiety often go unaddressed not for lack of desire to heal, but for lack of an accessible intervention that reaches the biological mechanism maintaining the symptoms. Stellate ganglion block is that intervention. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness for Richmond residents and patients from Rosenberg, Sugar Land, Missouri City, Pecan Grove, and greater Fort Bend County. Three Houston locations, open 5am–9pm, seven days a week.
Richmond TX - Care Closing the Gap
Fort Bend County has grown faster than nearly any county in the United States over the past two decades — one of the most diverse, economically dynamic counties in Texas, with Richmond at its center. That growth has brought enormous demographic diversity to the region: military families relocating to take advantage of southwest Houston’s housing values, agricultural and ranching workers managing the health consequences of physically and emotionally demanding work, healthcare workers at OakBend Medical Center absorbing occupational stress, and a large population of young families in the surrounding master-planned communities navigating the particular challenges that new parenthood brings.
What hasn’t grown at the same pace is access to specialized, evidence-based PTSD and anxiety care in the Fort Bend corridor. The gap between need and access is real — and it’s one reason stellate ganglion block matters particularly here. The 2026 PMC comprehensive review “Application of Stellate Ganglion Modulation in Mental Disorders” — published in Frontiers in Psychiatry — documents that SGB’s reach extends to postpartum depression, where patients experienced significant reductions in Hamilton Depression Rating Scale scores, Edinburgh Postnatal Depression Scale scores, and Pittsburgh Sleep Quality Index scores following SGB, “along with markedly decreased serum levels of adrenocorticotropic hormone, corticotropin-releasing hormone, and cortisol.” The shared biological substrate — HPA axis dysregulation and elevated stress hormones — connects postpartum depression and anxiety, PTSD, and chronic anxiety through the same autonomic mechanism that SGB directly addresses.
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 — connects the brain’s central autonomic control network to the sympathetic nerve supply of the head, neck, upper body, cardiovascular system, and thoracic organs. Its connections extend to the hypothalamus, amygdala, prefrontal cortex, and insular cortex — structures governing stress response, emotional regulation, temperature control, and threat detection. In PTSD, anxiety, and postpartum mood disorders, the dysregulation of this system through elevated nerve growth factor, chronically elevated norepinephrine, and HPA axis stress hormone overproduction maintains a state of physiological activation that therapy and medication often can’t fully resolve because they approach these conditions from the top down rather than at the autonomic system’s biological root.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
Understanding SGB's mechanism helps explain why a single anatomical intervention can address PTSD, chronic anxiety, postpartum depression, and sleep disorders through overlapping biological pathways.
Resetting the Sympathetic Nervous System
The 2026 Frontiers in Psychiatry review describes SGB's mechanism through two complementary regulatory pathways. The first — descending regulation — directly modulates sympathetic outflow from the stellate ganglion to the peripheral organs: reducing the elevated norepinephrine that chronic trauma, anxiety, and HPA axis dysregulation maintain, lowering the amygdala's threat-detection hyperresponsiveness, and allowing the autonomic nervous system to shift from sympathetic dominance toward parasympathetic balance. This descending pathway is responsible for the immediate, physical sense of release that many Richmond patients notice during the procedure itself.
The second pathway — ascending regulation — modulates neuroendocrine activity through the stellate ganglion's connections to the hypothalamus and the HPA axis. Trauma, chronic stress, and postpartum hormonal shifts all dysregulate the HPA axis: elevated cortisol and corticotropin-releasing hormone maintain a state of physiological stress that amplifies amygdala sensitivity and perpetuates anxiety, depression, and sleep disruption. SGB's connections to the hypothalamus allow it to moderate this HPA overactivation — which is why postpartum depression patients in the clinical studies showed measurable decreases in ACTH, CRH, and cortisol following SGB, alongside the improvements in mood and sleep quality that those hormone reductions produce.
Reducing Brain Inflammation and Hyperactivity
SGB's effects extend into the brain's inflammation and neuroplasticity domains. Animal model research documented in the 2026 review shows that "SGB suppresses hippocampal microglia inflammation" — the same inflammatory pathway that contributes to fear memory consolidation in PTSD and cognitive difficulties in postpartum depression. By reducing hippocampal inflammation, SGB may improve both the emotional processing capacity and the cognitive clarity that these conditions impair. The review also notes that "following SGB, weight and serum melatonin significantly increased" in research models — consistent with the sleep quality improvements that both PTSD and postpartum patients report as among the earliest and most consistent benefits of the procedure.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step has been designed for clarity, efficiency, and genuine accessibility for Richmond and Fort Bend County patients navigating the demands of family life, work, and a commute to Houston.
Step 1: Free Phone Consultation
No cost, no commitment. A clinical team member discusses your symptoms, treatment history, and what you’re hoping to change. You receive an honest assessment of whether SGB is clinically appropriate — including a direct answer if it isn’t.
Step 2: Medical Evaluation
Dr. Ho conducts a thorough pre-procedure evaluation: medical history, current medications, prior procedures, and contraindication review. Every question is answered before anything is scheduled.
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. 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 — 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 2026 Frontiers in Psychiatry comprehensive review — “Application of Stellate Ganglion Modulation in Mental Disorders and the Future Prospects of Physical Therapies” — synthesizes the complete spectrum of SGB’s evidence base and mechanisms. The review documents SGB’s dual pathway mechanism (ascending neuroendocrine modulation and descending sympathetic outflow regulation), confirms its established efficacy for PTSD, and provides the first comprehensive synthesis of emerging evidence for postpartum depression (measurable reductions in ACTH, CRH, cortisol, depression, and sleep disruption), treatment-resistant depression, generalized anxiety disorder, and sleep disorders. The review describes SGB as “suppressing hippocampal microglia inflammation and enhancing cognitive function” — providing a neuroinflammatory mechanism for the cognitive improvements patients report alongside emotional symptom reductions.
Key research findings:
- SGB’s dual pathway — ascending HPA axis modulation and descending sympathetic outflow regulation — addresses the biological substrate shared by PTSD, anxiety, postpartum depression, and sleep disorders simultaneously
- SGB for postpartum depression produced significant reductions in ACTH, corticotropin-releasing hormone, and cortisol — the stress hormones maintaining postpartum HPA axis dysregulation — alongside measurable improvement in mood and sleep scores
- The 2020 JAMA Psychiatry RCT established Level 1B evidence — the highest standard achieved for SGB in PTSD
- SGB suppresses hippocampal microglia inflammation, providing a neuroinflammatory mechanism for the cognitive improvements patients report in PTSD and postpartum presentations

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.
