There are other nerve blocks as well for nerve pain relief: A sympathetic nerve block is performed in order to determine if damage has occurred to the sympathetic nerve chain, a network of nerves that extends the length of the spine. Nerves of this kind control a portion of the involuntary functions of our bodies, like the opening and narrowing blood vessels. A stellate ganglion block is a type of sympathetic nerve block that can be performed to discern if there is damage to the nerve chain supplying the neck, head, arms and chest and, if so, whether it is the source of pain in those areas. While the stellate ganglion block is used mainly to diagnose pain and its source, it may provide nerve pain relief that will last past the duration of the anesthetic.
