What is Stellate ganglion block?
This procedure called a stellate ganglion block is where an injection containing local anaesthetic with or without a steroid is injected on to the Stellate ganglion. The Stellate ganglion is a collection of nerves which can be found either side of the Adams apple in the neck. This part of the nervous system in certain circumstances can cause pain and the other symptoms you are experiencing.
The Consultant feels that by injecting the local anaesthetic and possibly steroid on to Stellate ganglion it may give you some relief from the symptoms you are experiencing.
