The stellate ganglion is a group of nerves in your neck on either side of your voice box. These nerves are not the usual nerves that allow us to feel or move but rather they have specialized functions and work on the blood vessels, sweat glands and hair follicles.
A stellate ganglion block is an injection of local anesthetic (numbing medication) near the stellate ganglion that “turns off” these specialized nerves. It is used to help with pain in the head, arm and upper chest
You will lie down on your back on the procedure table. The front of your neck will be cleaned and a sterile towel placed over the area.
A specialized x-ray machine called a fluoroscope will be used to locate the area of the ganglion.
A localized anesthetic is administered into the skin of the neck for numbing. This will cause a second or two of discomfort.
The doctor will then insert a second needle into the area of the ganglion, again, using the fluoroscope for guidance. A small amount of dye will be injected through the needle to make sure that it spreads to the correct area.
Finally, the medication will then be injected through the needle and the needle will be removed. The procedure will only take a few minutes.
Stellate Ganglion Blocks are most often used to help with painful injuries to the nervous system such as:

A stellate ganglion block is a low risk procedure. There is a chance of bruising or soreness at the injection site following the procedure. Common side effects associated with numbing of the sympathetic nerves that indicate that the injection is on target are:
