What is a Stellate Ganglion Block?

A stellate ganglion block, also known as a sympathetic block, involves the injection of a local anesthetic into the front of the neck. Its primary purpose is to diagnose the source of pain in the head, face, arms, and chest. By blocking the sympathetic nerves that supply these areas, a stellate ganglion block may alleviate pain, swelling, color changes, and sweating in the upper extremities and improve mobility.

Am I a candidate for a Stellate Ganglion Block?

Your healthcare provider may suggest a stellate ganglion block if you are experiencing Reflex Sympathetic Dystrophy (RSD), Sympathetic Maintained Pain, Complex Regional Pain Syndrome, or Herpes Zoster (shingles) affecting your head, face, or arm.
