What Is a Stellate Ganglion Block (SGB)?
A Stellate Ganglion Block (SGB) is a minimally invasive procedure that involves injecting a local anesthetic around the stellate ganglion, a collection of sympathetic nerves located in the lower neck.
The stellate ganglion is part of the sympathetic nervous system, which regulates many involuntary body functions, including:
- Blood flow
- Heart rate
- Sweating
- Temperature regulation
- Stress (“fight-or-flight”) response
When the sympathetic nervous system becomes overactive or contributes to chronic pain, temporarily blocking these nerves may help reduce symptoms and improve function.
Stellate ganglion blocks have long been used in interventional pain management for select chronic pain conditions affecting the head, neck, upper extremities, and upper chest. Research continues to explore additional applications involving autonomic nervous system dysfunction.
What Conditions Can Stellate Ganglion Block Help Treat?
Stellate Ganglion Block may be recommended for carefully selected patients with conditions involving the sympathetic nervous system, including:
- Complex Regional Pain Syndrome (CRPS Type I & II)
- Reflex Sympathetic Dystrophy (RSD)
- Neuropathic pain
- Post-herpetic neuralgia (shingles nerve pain)
- Certain vascular disorders such as Raynaud’s phenomenon
- Sympathetically maintained pain affecting the arm, shoulder, neck, or face
SGB has also been studied as an off-label treatment for conditions including:
- Post-Traumatic Stress Disorder (PTSD)
- Anxiety related to sympathetic nervous system overactivity
- Dysautonomia
- Long COVID-associated autonomic symptoms
- Persistent post-concussion symptoms (Traumatic Brain Injury)
While early research is promising in some of these areas, evidence continues to evolve. Your physician will discuss whether SGB is appropriate based on your individual diagnosis and treatment goals.
What to Expect During an SGB Procedure
A Stellate Ganglion Block is performed as an outpatient procedure and typically takes 15 to 30 minutes.
Before treatment, the skin is cleaned and numbed with a local anesthetic. Using ultrasound guidance, fluoroscopy (X-ray guidance), or both, your physician carefully advances a small needle to the targeted nerve bundle before injecting a precise amount of local anesthetic.
Patients are observed for a short period following the procedure before returning home the same day.
Temporary effects such as drooping of the eyelid (Horner’s syndrome), nasal congestion, or a warm sensation in the arm are expected signs that the block has reached the intended nerves and usually resolve within several hours.
Is Stellate Ganglion Block Right for You?
You may be a candidate for an SGB if you:
- Have chronic neuropathic pain
- Have been diagnosed with Complex Regional Pain Syndrome (CRPS)
- Experience sympathetically maintained pain
- Have persistent nerve-related pain that has not improved with conservative treatment
- May benefit from modulation of sympathetic nervous system activity
During your consultation, our pain management specialists will review your symptoms, medical history, imaging studies, and previous treatments to determine whether a Stellate Ganglion Block is an appropriate part of your personalized care plan.

Potential Benefits of Stellate Ganglion Block
Advanced Neuropathic Pain Management
SGB is commonly used to help manage:
- Complex Regional Pain Syndrome (CRPS)
- Reflex Sympathetic Dystrophy (RSD)
- Chronic nerve pain
- Post-herpetic neuralgia
- Sympathetically maintained pain
By reducing abnormal sympathetic nerve activity, many patients experience improvements in pain, sensitivity, and function.
Support for PTSD & Stress Response Regulation
Stellate Ganglion Block has been investigated as an off-label treatment for PTSD and certain anxiety-related conditions. Some patients report improvements in hyperarousal, anxiety, and stress-related symptoms following treatment.
Although early clinical research is encouraging, SGB is not considered a first-line treatment for PTSD or anxiety, and it should be used alongside comprehensive mental health care when appropriate.
Improved Circulation & Autonomic Function
For select patients, SGB may improve circulation by reducing excessive sympathetic nerve activity.
It has been used in patients with:
- Raynaud’s phenomenon
- Certain vascular disorders
- Dysautonomia
- Sympathetic-mediated circulation problems
Patient outcomes vary depending on the underlying condition.
Migraine & Chronic Headache Management
Some patients with chronic migraines, cluster headaches, or occipital neuralgia may benefit from sympathetic nerve block therapy when conventional treatments have not been successful.
Treatment recommendations are individualized based on diagnosis and response to prior therapies.
Emerging Research in Long COVID
Researchers continue to study Stellate Ganglion Block as a possible treatment for selected patients experiencing persistent symptoms following COVID-19 infection, including:
- Brain fog
- Fatigue
- Autonomic dysfunction
- Exercise intolerance
Although early reports are encouraging, more research is needed to fully establish effectiveness.
Potential Role in Post-Concussion Recovery
Some patients experiencing persistent post-concussion symptoms have reported improvements in headaches, mental clarity, and autonomic symptoms following SGB.
Clinical research in this area remains ongoing, and treatment decisions should be individualized.
Benefits of Stellate Ganglion Block
Patients may benefit from:
- Minimally invasive outpatient treatment
- Targeted sympathetic nerve modulation
- Reduced chronic nerve pain
- Improved circulation in selected conditions
- Enhanced daily function
- Quick recovery
- Personalized treatment planning
- Reduced reliance on pain medications for some patients
Risks & Possible Side Effects
Stellate Ganglion Block is generally considered safe when performed by experienced physicians using image guidance. As with any injection procedure, potential risks include:
- Temporary hoarseness
- Temporary drooping eyelid (Horner’s syndrome)
- Difficulty swallowing
- Bruising
- Bleeding
- Infection
- Temporary numbness
- Nerve irritation
- Allergic reaction
- Rare injury to nearby structures, including the lung (pneumothorax)
Our physicians carefully review all risks, expected benefits, and alternative treatment options during your consultation.
Frequently Asked Questions
What is a Stellate Ganglion Block?
A Stellate Ganglion Block (SGB) is an image-guided injection of local anesthetic around the stellate ganglion, a group of sympathetic nerves located in the neck. It is commonly used to treat select chronic pain conditions involving the sympathetic nervous system.
What conditions can SGB treat?
SGB is most commonly used for sympathetically mediated pain conditions such as Complex Regional Pain Syndrome (CRPS), post-herpetic neuralgia, and certain vascular disorders. It is also being studied for PTSD, dysautonomia, and Long COVID-related autonomic symptoms, although these uses remain off-label.
How is a sympathetic nerve block different from a Stellate Ganglion Block?
A sympathetic nerve block refers to a group of procedures targeting different areas of the sympathetic nervous system. A Stellate Ganglion Block specifically targets the stellate ganglion located in the lower neck.
How long does an SGB procedure take?
Most Stellate Ganglion Block procedures take approximately 15 to 30 minutes and are performed on an outpatient basis.
Is Stellate Ganglion Block safe?
Yes. When performed by experienced interventional pain specialists using image guidance, SGB is generally considered safe. Serious complications are uncommon but can include bleeding, infection, nerve injury, or temporary changes in voice or swallowing.
How quickly does SGB begin working?
Some patients notice symptom improvement within hours or days, while others may require additional time or multiple treatments. Results vary depending on the condition being treated.
How many SGB treatments are needed?
The number of treatments varies by diagnosis and individual response. Some patients experience meaningful improvement after one injection, while others may benefit from a series of treatments.
Can SGB help with PTSD or anxiety?
