If you’re living with chronic nerve pain, Complex Regional Pain Syndrome (CRPS), or certain conditions involving the sympathetic nervous system, a Stellate Ganglion Block (SGB) may provide meaningful relief. At TOPS Institute, our board-certified interventional pain management specialists perform Stellate Ganglion Block procedures in Los Angelesusing advanced image-guided techniques to ensure precision, safety, and patient comfort.
SGB is a specialized sympathetic nerve block designed to interrupt abnormal nerve activity that contributes to chronic pain and dysfunction of the autonomic nervous system.
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:
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.
Stellate Ganglion Block may be recommended for carefully selected patients with conditions involving the sympathetic nervous system, including:
SGB has also been studied as an off-label treatment for conditions including:
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.
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.
You may be a candidate for an SGB if you:
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.
Our board-certified physicians specialize in advanced image-guided procedures that precisely target pain while minimizing discomfort and recovery time.
We utilize modern imaging technology, including ultrasound and fluoroscopy, to improve needle accuracy and maximize patient safety.
Every patient receives an individualized evaluation to determine whether SGB or another minimally invasive pain treatment offers the greatest potential benefit.
Stellate Ganglion Block may be incorporated into a broader treatment strategy that includes physical therapy, medications, regenerative medicine, or additional interventional procedures to optimize long-term outcomes.
SGB is commonly used to help manage:
By reducing abnormal sympathetic nerve activity, many patients experience improvements in pain, sensitivity, and function.
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.
For select patients, SGB may improve circulation by reducing excessive sympathetic nerve activity.
It has been used in patients with:
Patient outcomes vary depending on the underlying condition.
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.
Researchers continue to study Stellate Ganglion Block as a possible treatment for selected patients experiencing persistent symptoms following COVID-19 infection, including:
Although early reports are encouraging, more research is needed to fully establish effectiveness.
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.
Patients may benefit from:
Stellate Ganglion Block is generally considered safe when performed by experienced physicians using image guidance. As with any injection procedure, potential risks include:
Our physicians carefully review all risks, expected benefits, and alternative treatment options during your consultation.
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.
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.
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.
Most Stellate Ganglion Block procedures take approximately 15 to 30 minutes and are performed on an outpatient basis.
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.
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.
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.
Stellate Ganglion Block has been investigated as an off-label treatment for PTSD and certain anxiety-related symptoms. While some patients report improvement, evidence is still evolving, and SGB should not replace established psychiatric care or evidence-based mental health treatments.
Candidates are determined after a comprehensive evaluation that considers your diagnosis, symptoms, medical history, physical examination, imaging findings, and previous treatments.
Insurance coverage varies depending on the diagnosis. SGB is more commonly covered for recognized pain management indications than for off-label uses such as PTSD or anxiety. Our team can help review your insurance benefits and discuss available options.
If chronic nerve pain or dysfunction of the sympathetic nervous system is affecting your quality of life, our experienced interventional pain specialists can help determine whether Stellate Ganglion Block (SGB) is the right treatment for you.
