At Rushmore Pain & Medicine, we are often asked about the procedures we perform. One of our most common pain-management procedures is an epidural steroid injection, often referred to as an ESI.
An ESI is a corticosteroid injection given in tandem with a local anesthetic. Corticosteroids are anti-inflammatories that relieve the swelling and inflammation that can place pressure on nerves and other soft tissues, often causing pain. The local anesthetic is used to offer immediate pain relief since corticosteroids can take awhile to have an effect.
The term “epidural” refers to where the injection takes place, the area around the spinal cord and nerve roots called the “epidural space.”
