Lumbar sympathetic blocks
Injection needles will be positioned and then there are three main ways to produce the block: injection of a long acting local anaesthetic to produce a diagnostic block to safely see if your pain can be treated this way; injection of a neurolytic substance such as phenol or alcohol to destroy the lumbar sympathetic nerves; and the use of radiofrequency energy to similarly destroy the nerves in a highly controlled way.Stellate ganglion blocks
The stellate ganglion is a collection of autonomic sympathetic nerves, which lies in front of the spine at the level of your larynx. It can be a site where pain signals from the face, heart, or arm are processed. It can therefore sometimes be useful to block it.
