What is an epidural nerve block?
An epidural nerve block is the injection of corticosteroid medication into the epidural space of the spinal column. This space is located between the dura (a membrane surrounding the nerve roots) and the interior surface of the spinal canal formed by the vertebrae. After a local skin anesthetic is applied to numb the injection site, a spinal needle is inserted into the epidural space. To ensure accuracy and safety, our physicians perform the procedure under fluoroscopic (x-ray) guidance, using a contrast agent to confirm needle placement. Local anesthetic and corticosteroid anti-inflammatory medication are delivered into the epidural space to shrink the swelling around nerve roots, relieving pressure and pain. How long does it take? Epidural nerve blocks are performed on an outpatient basis. The procedure typically requires 20 to 30 minutes, including preparation time. It is followed by 45 minutes of observed recovery time. How often should this procedure be done? Up to three injection
