    Sympathetic Nerve Block

    What is it?

    A sympathetic nerve block is a nerve block of a nerve plexus, or bundle of nerves, that lie on the front side of the vertebral column. These bundles of nerves sense pain in the abdomen and pelvis.

    How does it work?

    Using fluoroscopic guidance, a needle is placed in the proximity of the nerve plexus and then local anesthetic, and sometimes steroid, are injected into the area.

    What conditions does it treat?

    Sympathetic nerve blocks are helpful for patients with abdominal or pelvic pain who have not received pain relief from more conservative therapies like physical therapy and medication management.
