Transforaminal and Sympathetic Nerve Blocks

A transforaminal or selective nerve root block is an injection of local anesthetic and steroid injected under x-ray guidance into the area where the nerve exits the spinal column. A block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve. This block may be diagnostic and/or therapeutic.

A sympathetic nerve block is injection therapy that targets the sympathetic nervous system, a series of nerves that spread out from your spine to your body to help control several involuntary body functions or body functions that you have no control over. These include blood flow, digestion, and sweating.
