Stellate Ganglion Block in Cinco Ranch, TX: Rapid Relief for PTSD, Anxiety, and Trauma
The 7,200 acres that became Cinco Ranch were designed for quality — master-planned trails along Buffalo Bayou, resort-style recreation, Katy ISD schools that consistently rank among the best in Texas, and a community identity built around the idea that where you live shapes who you can be. The people who chose Cinco Ranch expect what they invest in to perform. When PTSD, anxiety, or trauma-driven symptoms haven’t responded to therapy or medication — when the nervous system is still running at high alert despite everything that should have calmed it — stellate ganglion block is the intervention that operates at that biological level. Dr. Ho, board-certified anesthesiologist and former pediatrician, performs this ultrasound-guided procedure at Catalyst Health & Wellness, serving Cinco Ranch residents and patients from Katy, Fulshear, Westheimer Corridor, Sugar Land, and greater west Houston. Three Houston locations, open 5am–9pm, seven days a week.
Cinco Ranch One Procedure Many Conditions
Cinco Ranch is home to one of the more distinctive demographic profiles in the Houston metro: a large proportion of women between 40 and 60, many managing complex intersecting health conditions that conventional medicine often treats in separate siloes. PTSD or anxiety from life experience. Perimenopausal hot flashes that disrupt sleep, mood, and daily functioning. The chronic stress that compounds both. And an emerging body of research revealing that all three conditions share a common biological driver: elevated nerve growth factor, dysregulated norepinephrine, and a stellate ganglion that’s part of the overactivated sympathetic system maintaining them all.
The Cleveland Clinic Journal of Medicine has published a peer-reviewed review of SGB for vasomotor symptoms — the hot flashes and night sweats that affect 75% of menopausal women — noting that the procedure “may also have a modulatory role in thermoregulatory areas of the brain” and that it represents a promising nonhormonal treatment option for women with severe symptoms refractory to conservative care. A 2023 randomized controlled trial published in Frontiers in Endocrinology enrolled 40 perimenopausal women and found that SGB “significantly relieved perimenopausal hot flashes and effectively improved sleep quality” at 12-week follow-up — with Kupperman Menopause Scale scores and Pittsburgh Sleep Quality Index scores improving alongside hot flash frequency and severity. The mechanism — stellate ganglion blockade reducing the overactivated sympathetic signals maintaining both hot flashes and stress-related symptoms — is the same mechanism documented in PTSD research. For Cinco Ranch patients managing anxiety, PTSD, and perimenopausal symptoms simultaneously, that shared biological substrate means one intervention may address multiple conditions at once.
What is Stellate Ganglion Block?
The stellate ganglion is a cluster of sympathetic nerves at the base of the neck — the anatomical product of the inferior cervical and first thoracic ganglia fusing into a single relay node, positioned just anterior to the seventh cervical vertebra. It connects the brain’s central autonomic network to the sympathetic nerve supply of the head, neck, upper body, and cardiovascular system. Its connections extend to the hypothalamus, amygdala, prefrontal cortex, and insular cortex — structures central to temperature regulation, stress response, emotional regulation, and threat detection.
Research consistently shows powerful results:
What Our Patients Say
How Stellate Ganglion Block Works
For Cinco Ranch's analytically oriented community, the shared mechanism connecting PTSD, anxiety, and perimenopausal symptoms through the stellate ganglion is worth understanding in full.
Resetting the Sympathetic Nervous System
The nerve growth factor (NGF) and norepinephrine cascade is central to all three conditions that SGB addresses most powerfully. In PTSD and anxiety, trauma drives elevated NGF, which causes sympathetic nerve sprouting and increased norepinephrine production, maintaining the amygdala in a hyperresponsive state. In perimenopause, estrogen decline allows NGF to rise unchecked — the same pathway, triggered by hormonal change rather than trauma — producing the sympathetic surges in the hypothalamic thermoregulatory center that generate hot flashes and night sweats. The mechanism is so similar that the original hypothesis connecting PTSD and hot flash treatment through SGB was published by Dr. Eugene Lipov in 2009: both conditions share the estrogen-NGF-norepinephrine interaction, and both respond to stellate ganglion blockade interrupting that interaction at the same anatomical source.
By temporarily blocking stellate ganglion nerve conduction, SGB allows NGF to normalize, norepinephrine to drop, and the downstream systems — amygdala threat-detection in PTSD, hypothalamic thermoregulation in menopause — to recalibrate. The Cleveland Clinic Journal of Medicine notes that SGB's benefit for hot flashes may be related to its "modulatory role in thermoregulatory areas of the brain" — specifically its connections to the hypothalamus, the temperature-regulating center where the sympathetic surges of hot flashes originate.
Reducing Brain Inflammation and Hyperactivity
Beyond the NGF/norepinephrine reset, SGB produces measurable changes in how the brain's autonomic network processes signals. The stellate ganglion's documented connections to the hypothalamus, amygdala, insular cortex, and prefrontal cortex are why a 15–20 minute neck procedure can produce changes in emotional regulation, threat detection, and even thermoregulation simultaneously. These are not separate systems that SGB happens to benefit in parallel — they are interconnected nodes of the same autonomic network, all of which receive input through the sympathetic pathway that the stellate ganglion relays.
For Cinco Ranch patients who've been asking their gynecologist, their psychiatrist, and their therapist to address what are actually interconnected manifestations of the same underlying sympathetic dysregulation, this convergence around a single anatomical target is both clinically coherent and practically useful.

Your Stellate Ganglion Block Journey at Catalyst Health & Wellness
Every step has been designed to be clear, supported, and accessible for Cinco Ranch patients with demanding schedules and high clinical standards.
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 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 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. 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 PTSD treatment.
The 2023 randomized controlled trial in Frontiers in Endocrinology enrolled 40 perimenopausal women and randomized them to receive either six consecutive SGB treatments or six consecutive saline placebo treatments over 12 weeks. Hot flash symptom scores, Kupperman Menopause Scale scores, and Pittsburgh Sleep Quality Index scores all decreased significantly in the SGB group. Researchers concluded that SGB represents “a safe and effective nonhormone replacement therapy that significantly relieved perimenopausal hot flashes and effectively improved sleep quality.” The underlying mechanism — stellate ganglion blockade reducing the NGF/norepinephrine pathway that estrogen decline has unleashed — directly parallels the PTSD mechanism, explaining why one intervention produces benefit across both conditions.
Key research findings:
- SGB produces significant reductions in perimenopausal hot flash scores, menopausal symptom scores, and sleep quality scores in a 12-week RCT — a clinical benefit sharing the same biological mechanism as SGB’s PTSD effects
- The Cleveland Clinic Journal of Medicine documents SGB as a nonhormonal treatment option for vasomotor symptoms through its modulatory role in thermoregulatory brain areas
- The 2020 JAMA Psychiatry RCT established Level 1B evidence for SGB in PTSD — the highest clinical standard yet achieved for this procedure
- The shared NGF/norepinephrine pathway linking PTSD, anxiety, and menopausal hot flashes explains why a single anatomical intervention can address multiple conditions simultaneously
Why Choose Catalyst Health & Wellness for Stellate Ganglion Block in Cinco Ranch
01
Led by Dr. Ho – Anesthesiology Expertise
SGB requires nerve block anatomy expertise, ultrasound guidance proficiency, and the clinical judgment to manage anesthetic delivery adjacent to major vascular structures. Dr. Ho's board certification in anesthesiology covers those skills at their foundation — not as add-ons. Cinco Ranch residents who apply quality standards to every major decision deserve that standard in their clinical care. His former career as a pediatrician ensures that precision is paired with genuine attentiveness to how care feels from the patient's perspective.
02
Ultrasound-Guided Precision
The 2023 Frontiers in Endocrinology RCT specifically uses “ultrasound-guided SGB” — imaging guidance that allows direct visualization of the stellate ganglion and surrounding anatomy. Every SGB at Catalyst uses real-time ultrasound. This is the standard of care for a procedure performed in proximity to major cervical vascular structures, and it’s the only approach Dr. Ho uses.
03
Whole-Person Approach
Many Cinco Ranch patients present with overlapping conditions — PTSD and anxiety, or perimenopause and panic, or complex trauma and sleep disruption — that conventional medicine addresses separately. Our team engages with the full picture rather than treating each symptom in isolation. Treatment plans reflect the complete clinical context and are coordinated with existing psychiatric, gynecological, and primary care providers. What this means:
- Treatment shaped around your complete symptom profile and clinical history
- Coordination with your gynecologist, psychiatrist, or primary care provider if appropriate
- Guidance on combining SGB with Catalyst’s other treatments for comprehensive outcomes
- Ongoing clinical support extending beyond the procedure itself
04

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.
