Stellate Ganglion Nerve Block

The stellate ganglion is part of the sympathetic nervous system that is located in your neck, on either side of your voice box.

What is a Stellate Ganglion Nerve Block?

This minimally invasive procedure is performed by our specialist using a steroid and anti-inflammatory mixture injected into or around your stellate ganglion nerves to relieve pain in the head, neck, upper arm and upper chest. It also can help increase circulation and blood supply to the arm and is performed under fluoroscopy (X-ray) guidance.

What to expect during a Stellate Ganglion Nerve Block procedure

Your pain specialist will have you lay on your back while they numb the surrounding skin with a local anesthetic. With fluoroscopic guidance, a thin needle is guided into your neck, near your voice box, where medication is administered. Usually, the procedure takes less than 30 minutes, and you can go home the same day after being monitored in the recovery room.

What to expect after a Stellate Ganglion Nerve Block procedure

Do not drive or do any rigorous activity for 24 hours after your procedure. You can return to your normal activities the next day. Some patients experience a hoarse voice for a few hours, once your voice returns to normal, you may begin to sip water through a straw and gradually work up to eating solid foods.

Pain relief is different for each patient. Some may be pain-free for days, weeks, or month and usually there is a need for multiple procedures. The relief tends to last longer with each treatment.
