If you're considering stellate ganglion block (SGB) for trauma, anxiety, or chronic stress, you're probably asking the same questions I hear every day:

Am I a candidate?
Will it work?
How long does it last?
Is it safe?

My goal is simple: help you make an informed, confident decision.

When I sit down with patients to discuss this treatment, I am not just explaining a procedure. I am helping them understand what is driving their symptoms and whether targeting the nervous system makes sense for them.

What most people call a stellate ganglion block is a treatment of the sympathetic nervous system, the part of your body responsible for the fight-or-flight response. In many patients dealing with trauma, anxiety, or chronic stress, that system becomes overactive and remains that way. What I hear most often is not only emotional distress but also physical symptoms, including panic attacks, poor sleep, irritability, and a constant sense of being on edge. The goal is not to mask those symptoms but to address the source of the injury - the overactive response - so the body can begin to regulate again.

It is also important to clarify our approach to SGB at Reset. We do not offer just a standard stellate ganglion block. What we perform is called Neuro Sympathetic Reset (NSR), our more advanced and refined approach designed to optimize outcomes. This includes dual-level targeting of the cervical sympathetic chain, a structured treatment process, and a strong emphasis on trauma-informed care and integration after the procedure. If you would like to learn more about our approach, visit our Neuro Sympathetic Reset (NSR) treatment page.

The key point is that the procedure itself is only one part of the process. How it is performed, how patients are prepared, and how they are supported afterward all play a major role in outcomes.

Am I a Good Candidate?

One of the most important parts of my process is determining who is actually a good candidate.

At Reset, I use a structured, objective intake process with validated clinical

assessments for PTSD, anxiety, and depression. I encourage every patient to start with our free self-assessment, which measures symptoms using tools like the PCL-5, PHQ-9, and GAD-7. This gives both you and me a clearer understanding of what you are experiencing.

At the same time, I always emphasize that numbers alone do not tell the full story. I have seen patients with lower trauma scores still benefit, particularly when their symptoms are more physical in nature. In those cases, the decision becomes more individualized, which is why we offer free consultations to review your specific situation and determine the best path forward.

Another question that commonly comes up is, "Will this help my other conditions?"

Patients often ask whether this treatment can improve issues like chronic pain, POTS, autoimmune or inflammatory conditions, migraines, traumatic brain injury, gastrointestinal symptoms, or functional neurologic disorders. The answer is that these conditions can absolutely improve, but typically not because we are treating them directly. Instead, we are addressing the underlying nervous system dysregulation, including chronic stress, poor sleep, and persistent hyperarousal, all of which can significantly worsen these conditions. As the nervous system begins to regulate, I often see meaningful improvements in both symptom severity and frequency.

In addition, one of my research interests is understanding how the inflammatory system responds after sympathetic blockade and how this may directly influence certain conditions, particularly traumatic brain injury, neurologic disorders, and autoimmune disorders. I recently published a case report on traumatic brain injury and post-concussive symptoms, demonstrating improvement following this approach.

However, it is important to be clear that Neuro Sympathetic Reset is not a direct treatment for these conditions, and the literature is still evolving. That said, we are seeing very encouraging clinical results, especially in conditions that are heavily influenced by stress and nervous system dysregulation.

How Long Does SGB Last?

Another consideration is, "How long will the effects last?"

The honest answer is that it varies. Some patients notice improvement within hours to days, while others experience a more gradual shift. Many patients will have meaningful relief lasting months to years, and some benefit from a repeat treatment. You can view our clinical outcomes here.

What I focus on most is not just duration, but opportunity. When the nervous system is no longer stuck in a constant fight-or-flight state, it creates a window in which real healing can take place.

Is Stellate Ganglion Block Safe?

Safety is understandably a major consideration for most patients.

When performed with real-time ultrasound guidance and precise technique, this procedure is very safe. In my practice, I have extensive experience with cervical spine and ultrasound-guided interventions, and I take every step of the process with careful attention to detail, patient comfort, and safety.

There are expected temporary effects such as a drooping eyelid, regional numbness, or mild hoarseness, all of which resolve within several hours. More serious complications are exceedingly rare. In my experience, patients consistently find the procedure to be much quicker, smoother, and more comfortable than they anticipated.

As I guide patients through this decision, I often come back to a few key questions:

Do your symptoms feel like your body is stuck in overdrive?
Have you tried traditional approaches but still feel limited by your symptoms?
Do you want to stop masking your symptoms and start treating the underlying injury?
Are you open to addressing the nervous system directly while also committing to the work that comes afterward?

If the answer is yes, then Neuro Sympathetic Reset may be a very reasonable option to consider.

Our understanding of trauma continues to evolve. While traditional approaches have often focused on coping and symptom management, growing research highlights the important role of the nervous system in recovery. My goal is not simply to help patients manage symptoms, but to help create the conditions where healing becomes possible.

Over the years, I have had the privilege of watching many individuals reclaim their lives, reconnect with their families, and rediscover hope. Many have generously shared their experiences and recovery stories on our testimonials page, offering encouragement to others considering their own healing journey.

If you are considering this treatment, I encourage you to start with our free online assessment to determine whether Neuro Sympathetic Reset may be right for you.

Frequently Asked Questions

Is Neuro Sympathetic Reset different from a traditional stellate ganglion block?

Yes. Neuro Sympathetic Reset (NSR) is our advanced approach to stellate ganglion block that incorporates dual-level targeting, real-time ultrasound guidance, trauma-informed care, and structured support before and after treatment.

How quickly does SGB work?

Some patients notice improvements within hours, while others experience more gradual changes over several days or weeks. Response times vary from person to person.

How long do the effects of SGB last?

Many patients experience relief lasting months or even years. Some individuals benefit from repeat treatments if symptoms gradually return.

Is a stellate ganglion block safe?

When performed with ultrasound guidance and proper technique, SGB is considered very safe. Temporary effects such as eyelid drooping, hoarseness, or regional numbness are expected and typically resolve within a few hours.

Can SGB replace therapy or medications?

Neuro Sympathetic Reset is not intended to replace therapy, medications, or other treatments. Instead, many patients find that regulating the nervous system helps them engage more effectively in counseling, exercise, healthy sleep, and other aspects of recovery. Treatment plans should always be individualized.

Can SGB help conditions other than PTSD?

Although SGB is most commonly used for PTSD, anxiety, trauma-related symptoms, and chronic stress, some patients also report improvements in sleep, migraines, chronic pain, post-concussive symptoms, and symptoms associated with autonomic dysfunction. Research in these areas is still evolving.
