The Stellate Ganglion Block is an injection that is used to diagnose and treat pain coming from the sympathetic nerves. Shingles and complex regional pain syndromes are commonly treated with a Stellate Ganglion Block.
To receive this treatment, a patient lies on his/her back and anesthetics are administered to help the patient relax and to numb the associated tissue down to the Ganglion nerves. A needle is then inserted through the anesthetized tissue, and a contrast dye is injected to identify the painful areas. The Stellate Ganglion Block, an injection combining anesthetics, saline and anti-inflammatory medicine, are inserted around the Ganglion nerves to prevent pain signals from reaching the brain.
