Stellate Ganglion Block (SGB) Therapy
Transformative Relief for PTSD and Chronic Pain
Stellate Ganglion Block (SGB) therapy is an innovative, evidence-based treatment aimed at providing effective relief for symptoms associated with Post-Traumatic Stress Disorder (PTSD), chronic pain, and related autonomic disorders. This groundbreaking therapy offers new hope for patients seeking to regain control over their lives.
A Stellate Ganglion Block (SGB) is an injection of medication into a collection of nerves at the bottom of the front side of your neck. It can help treat a variety of conditions, such as:
What is Stellate Ganglion Block Therapy?
The anatomical location of the stellate ganglion is on the front side of the neck next to the C7 and T1 vertebrae. SGB therapy is a minimally invasive procedure that involves the precise injection of a local anesthetic into the stellate ganglion—a collection of nerves located in the neck responsible for regulating the body’s stress response. By temporarily blocking these nerves, SGB therapy effectively calms overactive nerve responses, resetting the body’s stress response system and offering rapid, lasting relief.
The entire procedure typically takes between 20 to 30 minutes, and most patients can return home the same day, making it a convenient and efficient option for those seeking relief from debilitating symptoms.
The stellate ganglion provides most of the sympathetic nerve signals to your head, neck, arms and a portion of your upper chest. Your sympathetic nervous system is part of your autonomic nervous system. It’s responsible for many functions your body controls without you thinking about them. This can include control of your heart rate, blood pressure, sweating and other functions.
Stellate Ganglion Blocks Can be Used for Mental Health Conditions
Proven Results: Stellate Ganglion Block (SGB) for PTSD
Since 2010, Stellate Ganglion Block (SGB) has been used in U.S. military treatment centers to help thousands of service members struggling with symptoms of post-traumatic stress disorder (PTSD). Originally developed to support elite combat teams by restoring focus and resilience, SGB is now being recognized more broadly for its therapeutic potential.
Over 15 peer-reviewed studies since 2008 have shown that SGB can significantly reduce PTSD symptoms. In 2019, a major breakthrough came with a large, multi-center clinical trial published in JAMA Psychiatry. This study confirmed that SGB produced twice the effect compared to a placebo procedure—meeting the highest standard of medical evidence (Level 1).
With this strong scientific backing, many leading clinicians now recommend SGB as part of comprehensive PTSD treatment. At Neurotherapy Montreal, we are proud to offer this cutting-edge, evidence-based intervention to support your healing journey.

Q & A at Neurotherapy Montreal: Stellate Ganglion Block
1. A healthcare provider may give you IV medication to help you relax.
2. You will lie on your back on a procedure table, and your neck will be cleaned and disinfected.
3. A thin needle will be used to inject a local anesthetic near your voice box.
4. Using ultrasound or fluoroscopic imaging guidance, a second needle will be inserted to carefully inject the anesthetic medication.
5. The entire procedure typically takes less than 30 minutes.
After the procedure, you will be monitored in a recovery room for about 40 to 60 minutes to ensure there are no complications. Your healthcare provider will give you post-care instructions, and you will need someone to drive you home.
The success of the stellate ganglion block varies from person to person. Some individuals experience immediate pain relief, but it may return as the anesthetic wears off. Others may enjoy longer-term relief, allowing them to reduce medication use and increase physical therapy participation.
The duration of pain relief varies among individuals. Some people may be pain-free for days or weeks. A series of injections is often necessary to maintain pain relief, ranging from two to more than ten treatments. Typically, the relief lasts longer with each successive treatment.
