If you’ve tried everything from medications and therapy to lifestyle changes and still feel stuck in a cycle of nervous system dysfunction, you’re not alone. At Interventional Orthopedics of Washington (IOW), we understand how exhausting and discouraging that can be. That’s why we offer targeted treatments like the Stellate Ganglion Block (SGB) to help restore calm, function, and hope.
SGB is a specialized, image-guided nerve block that can help reset an overactive sympathetic nervous system. For individuals suffering from post-traumatic stress disorder (PTSD), chronic pain conditions, or dysautonomia, this treatment offers a promising path toward relief.
Understanding The Stellate Ganglion and Sympathetic Nervous System
The stellate ganglion is a collection of sympathetic nerve cells located in the lower neck. These nerves regulate automatic bodily functions including:
Heart rate and blood pressure
Body temperature and sweating
Stress (fight-or-flight) responses
Blood flow to organs and extremities
Chronic trauma, injury, or illness can cause the sympathetic nervous system to become overactive, keeping the body in a constant state of stress and contributing to a range of debilitating symptoms.
What is a Stellate Ganglion Block?
Stellate Ganglion Block (SGB) is a minimally invasive injection of local anesthetic near the stellate ganglion performed under ultrasound or fluoroscopy guidance. This temporarily interrupts sympathetic nerve signals, creating a “reset” that allows the nervous system to return to a more regulated state.
The Procedure Includes:
Ultrasound- or fluoroscopy-guided needle placement
Local anesthetic injection to block the sympathetic nerve cluster
A brief recovery period for monitoring
Potential relief lasting days to months, depending on the individual

How SGB Helps With PTSD, Pain, and Dysautonomia
PTSD Relief
PTSD is not only psychological, it’s also physical. When the fight-or-flight system is stuck in overdrive, symptoms like hypervigilance, panic attacks, and sleep disturbances become daily obstacles. SGB can help:
Reduce nightmares, anxiety, and emotional reactivity
Improve sleep and mental clarity
Enhance outcomes of therapy and other trauma-focused care
Chronic Pain Syndromes
Conditions like Complex Regional Pain Syndrome (CRPS) and other neuropathic pain disorders involve abnormal sympathetic nerve activity. SGB may:
Decrease nerve hypersensitivity and pain
Improve range of motion and reduce inflammation
Enhance tolerance for physical therapy
Dysautonomia and POTS
Dysautonomia, including Postural Orthostatic Tachycardia Syndrome (POTS), can cause extreme fatigue, dizziness, brain fog, and irregular heart rate. SGB helps by:
Normalizing cardiovascular responses
Reducing lightheadedness and fatigue
Supporting nervous system regulation without medications
Though not a cure, SGB is an important tool in a broader, personalized treatment plan that may include functional medicine, nutrition, and rehab.
Who Is a Candidate for Stellate Ganglion Block?
SGB is often considered for individuals with treatment-resistant PTSD, CRPS, or dysautonomia who haven’t found relief through conventional therapies. You may be a candidate if you:
Experience persistent trauma-related or autonomic symptoms
Are in good overall health and not allergic to anesthetics
Are open to a multidisciplinary care approach
A consultation at IOW includes a detailed health assessment, imaging review, and personalized treatment planning.
What to Expect During and After the Procedure
The SGB procedure takes about 15-30 minutes and is done on an outpatient basis. Using ultrasound or fluoroscopy, our specialists carefully inject the anesthetic near the stellate ganglion to ensure maximum precision and safety.
After the injection, you may notice:
Numbness or tingling in the arm or face
Mild drooping of the eyelid (Horner’s Syndrome)
Soreness or minor bruising at the injection site
These effects are temporary and usually resolve within hours. Many patients experience symptom improvement within a few days. Depending on your condition, a single injection may be sufficient, or a series may be recommended.
You can resume most normal activities the same day though we advise avoiding strenuous exercise for 24-48 hours.
Safety and Potential Risks
SGB is a low-risk procedure when performed by trained, board-certified specialists like those at IOW. Our team uses real-time imaging to maximize precision and safety.
Rare risks include:
Infection at the injection site
Nerve injury or bleeding
Temporary difficulty swallowing or hoarseness
We provide thorough pre- and post-care instructions to support your recovery and peace of mind.
