About the Stellate Ganglion Nerves
The stellate ganglion nerves travel along both sides
of your spine. They are associated with a wide
range of bodily functions that you don't consciously

Inserting the Needle
The physician inserts a needle and carefully guides
it to the nerves of the stellate ganglion. The
physician typically uses an x-ray device called a

where you were given the injection may feel warm
and tingly. Your voice may be hoarse. You may
have nasal congestion, a flushed face and a droopy
eye. These effects are normal, and they usually
disappear after a few hours. You may need to
return for more injections in the future.
