Sympathetic Nerve Blocks
A sympathetic nerve block is an injection of local anesthetic used to diagnose damage in the sympathetic nerve network along the spine. These nerves are located on either side of the lumbar section of the spine, and control some of the involuntary functions of the body, such as sweating, blood flow, and digestion.

Benefits of Sympathetic Nerve Block Injections
While it is mainly used as a diagnostic test, a sympathetic block can also be used for temporary pain relief. Some of the benefits include:
Pain relief in the lower back and lower extremities
Reduced swelling
Allows your physician to better understand the source of your pain
Improved mobility and lower function
Improvement in color
Increased blood flow
Decreased amount of excessive sweating
