What Is a Stellate Ganglion Block?

A Stellate Ganglion Block (SGB) is an ultrasound-guided injection of local anesthetic near a cluster of sympathetic nerves in the neck called the stellate ganglion. These nerves play a role in the body's "fight or flight" response, and in some chronic pain conditions, an overactive sympathetic nervous system can keep pain signals firing long after an injury has healed. By temporarily calming this nerve cluster, an SGB can interrupt that cycle and provide meaningful relief for certain chronic pain conditions. At Premium Sports & Orthopedic Center, Dr. Erick Green performs SGB using ultrasound guidance for precision and safety. Book a consultation to find out if SGB may help your condition.

FAQs

Learn More About Stellate Ganglion Block (SGB)

What is a Stellate Ganglion Block?

A Stellate Ganglion Block is an ultrasound-guided injection of local anesthetic near the stellate ganglion, a cluster of sympathetic nerves in the neck, used to calm an overactive nervous system that may be contributing to chronic pain.

How does SGB work?

The sympathetic nervous system can, in some chronic pain conditions, keep pain signals active even after the original injury has healed. Temporarily blocking the stellate ganglion can interrupt that cycle and reduce pain.

Is SGB safe?

SGB is a well-established procedure. Dr. Green uses ultrasound guidance to improve precision and safety, and monitors patients for a short period after the injection.

Does SGB hurt?

Most patients feel a brief pressure or stinging sensation during the injection, similar to other local anesthetic injections.

What conditions is SGB used for?

SGB is most often used for Complex Regional Pain Syndrome (CRPS), sympathetically-maintained chronic pain, and certain cases of chronic neuropathic pain.

How long does relief from SGB last?

This varies by patient and condition. Some people get lasting relief from a single injection, while others need a short series for the best result.

Is there recovery time after SGB?

Most patients are monitored briefly in the office after the injection and can go home the same day, though you'll need someone to drive you.

Has SGB been studied for anything besides pain?

Yes, SGB has also been studied for other sympathetic-nervous-system-related conditions in medical research. Talk to Dr. Green about whether SGB is an appropriate option for your specific situation.

Is SGB covered by insurance?

Coverage varies by plan and diagnosis. Our team can review your options during your consultation.

Who is a good candidate for SGB?

People with chronic pain conditions, particularly those involving an overactive sympathetic nervous system, who haven't found relief with other treatments may be good candidates. Dr. Green will evaluate your history to confirm.
