When the sympathetic nervous system stays locked in a state of high alert, sleep, mood, and focus all suffer, and the body keeps bracing for a threat that never passes. The Dual Stellate Ganglion Block (DSGB) is a non-surgical procedure that places local anesthetic near the stellate ganglion, a cluster of nerves in the neck that drives the fight-or-flight response. By temporarily interrupting that overactive signaling, the procedure is designed to help recalibrate the nervous system toward a calmer baseline, addressing the root mechanism behind PTSD, severe anxiety, and trauma-linked insomnia rather than masking the symptoms with long-term medication.
This guide explains the Nervous System Reset, a Dual Stellate Ganglion Block (DSGB) performed under medical supervision to calm an overactive sympathetic nervous system. It covers what the procedure is, who may be a candidate, how the injection works, what it helps with, the benefits and the real risks, how it compares to medication, what to expect, and what to consider on cost. Every recommendation begins with an individual evaluation, because responses vary and this is specialized care.
What Is Nervous System Reset (SGB)?
Answer: Nervous System Reset is a physician-administered Stellate Ganglion Block, a precise injection of local anesthetic near a cluster of nerves in the neck designed to calm an overactive sympathetic, or fight-or-flight, response.
The stellate ganglion is part of the sympathetic chain that helps regulate the body's stress reactions. By temporarily interrupting overactive signaling at this point, the procedure can support a recalibration of the nervous system toward a calmer baseline. At AgeRejuvenation we use a dual block, treating both sides for a more complete effect, and the procedure is performed with imaging guidance under careful medical supervision. The Cleveland Clinic explains how the sympathetic nervous system drives the fight-or-flight response that this treatment is meant to quiet.
Who Is a Candidate for a Stellate Ganglion Block?
Answer: Candidates are typically adults with PTSD, severe anxiety, or trauma-linked insomnia tied to an overactive stress response, often after medications or therapy alone have not fully calmed the physical alarm.
The strongest fit is someone whose symptoms have a clear physiological component: a racing heart, constant tension, hypervigilance, and broken sleep that persist even with other care. Candidacy is decided after a thorough intake and a safety screen, not by symptoms alone. Because the procedure is not appropriate for everyone, our physicians review your history, current medications, and goals before recommending it.
Signs an Overactive Stress Response May Be the Cause
Answer: Common signs are persistent hypervigilance, a body that stays braced for danger, a racing heart, muscle tension, irritability, and sleep that stays shallow despite exhaustion.
These symptoms often trace back to a sympathetic nervous system stuck in the on position long after a stressful or traumatic period has passed. One symptom rarely travels alone, and the cluster of physical agitation, poor sleep, and emotional reactivity is what points toward an overactive stress response rather than a single isolated problem. An evaluation confirms the pattern before any procedure is considered.
How Does the Dual Stellate Ganglion Block Work?
Answer: A physician places local anesthetic near the stellate ganglion on each side of the neck, briefly interrupting overactive sympathetic signaling so the nervous system can reset toward a calmer baseline.
The injection is guided by imaging for precision, and the medication used is a standard local anesthetic. According to peer-reviewed stellate ganglion block research in military veteran PTSD populations, interrupting signaling at this nerve cluster has been associated with reduced PTSD symptom severity in studied groups. The effect is not a sedative that wears off in hours; the goal is a recalibration that many people describe as a sense of settling within hours to days. Responses vary, which is why follow-up is part of the plan.
What Nervous System Reset (SGB) Helps With
Answer: The treatment is used for trauma-linked stress and hypervigilance, persistent anxiety with a strong physical component, and sleep disruption tied to an overactive stress response.
For individuals carrying the weight of past trauma, the body can remain primed for danger long after the event, and the procedure is designed to ease that physiological hypervigilance. When anxiety has a strong physical component, calming the sympathetic drive can shift how the body feels, which many patients say makes therapy and lifestyle changes feel more accessible. And because an overstimulated nervous system frequently sabotages rest, quieting that signaling can support a return to deeper, more restorative sleep.
Benefits of the Nervous System Reset
Answer: The aim is durable calm at the source rather than ongoing symptom suppression, with potential improvements in hypervigilance, anxiety, sleep, and the ability to engage in other supportive care.
For many patients the practical benefit is that the constant internal alarm finally softens. Unlike daily medication that acts broadly on brain chemistry, the DSGB intervenes at the anatomical structure driving the stress response, which is why some people pursue it after years of managing symptoms without addressing the underlying activation. The size and durability of any benefit depend on the individual, which is exactly why honest evaluation and follow-up matter.
DSGB vs. Medication-Based PTSD Treatment
Answer: Medication manages symptoms through systemic effects on brain chemistry, while the DSGB targets the stellate ganglion directly; some patients combine both rather than choosing one.
| Approach | How it works | Frequency | Often suits |
|---|---|---|---|
| Dual Stellate Ganglion Block | Local anesthetic near the neck nerve cluster interrupts overactive sympathetic signaling | A procedure, with follow-up as needed | Those whose symptoms have a strong physical, hypervigilant component |
| Daily medication | Systemic effects on brain chemistry to manage symptoms | Ongoing, daily | Those who prefer or need continuous pharmacologic support |
| Talk-based therapy | Addresses thoughts, behaviors, and processing of trauma | Recurring sessions | Those working through the cognitive and emotional side of trauma |
The right path is individual, and these approaches are not mutually exclusive. Many people find that calming the physical alarm with a block makes therapy and other supportive practices more effective, which is why our team discusses combinations openly during consultation.
Side Effects and Risks of the Procedure
Answer: Most side effects are temporary and related to the local anesthetic, such as mild neck soreness, a droopy eyelid, a hoarse voice, or facial flushing on the treated side that resolves as the medication wears off.
Like any injection procedure, the DSGB carries risks, and serious complications are uncommon when it is performed by trained physicians with imaging guidance. The U.S. National Library of Medicine describes how a local anesthetic temporarily blocks nerve signaling, which is the mechanism behind both the intended effect and the short-lived side effects. Because individual response and medical history shape risk, we screen carefully beforehand and review what to expect, rather than treating the procedure as routine for everyone.
Is the DSGB FDA Approved for PTSD?
Answer: The medications used are FDA approved, but the FDA has not approved them specifically for PTSD treatment; clinical and military studies show promising results without guaranteed outcomes.
This is an honest distinction we make upfront. The local anesthetic is an established, approved medication; using it as a stellate ganglion block for trauma-linked symptoms is supported by published research but is not an FDA-cleared indication. We encourage patients to review the evidence and their individual situation with our team before deciding.
What to Expect and What It Costs
Answer: The DSGB is an outpatient procedure performed without general anesthesia, with most patients resuming normal activity shortly after; cost varies because it is a specialized service not universally covered by insurance.
The procedure itself is completed in a clinical setting, and protocol length or any follow-up depends on your individual response, which we discuss during consultation. Because coverage varies by insurer and plan, our team walks you through payment options, including our financing program, before you begin. The goal is a clear plan with no surprises, built around an honest conversation about what the procedure can and cannot do.
