Stellate ganglion block
A stellate ganglion block is done most often for people with RSD (Reflex Sympathetic
Dystrophy), also called CRPS (Complex Regional Pain Syndrome) of the arms. RSD
may result from an impaired sympathetic nervous system (the fight or flight part of our
nervous system). Typically RSD occurs after an injury, fracture, or surgery to the arm
resulting in a very sensitive upper extremity with vascular changes such as edema
and/or color changes and often decreased range of motion. The stellate ganglia lives
in front of the lower cervical spine on each side of your voice box. Blocking the ganglia
interrupts the sympathetic nervous system in an attempt to “reset” the sympathetic
nervous system. With a sympathetic block, you should not experience numbness or
weakness, however, you should feel a warmth in your extremity. A sympathetic block
allows less pain and better movement of the extremity
