The epidural steroid injection is the placement of a steroid and local anesthetic, a powerful antinflammatory agent, into the epidural space which approximates the disc and spinal column.

What is the purpose of this procedure?

The goal of the epidural injection is to shrink the swelling in the bulging or herniated disc, and to decrease any inflammation that surrounds the disc and may be pressing on a spinal nerve.

What happens during the procedure?

• The epidural is done as an outpatient procedure
• A local anesthetic is used to numb the skin.
• The epidural space is located and the needle is positioned appropriately.
• If the injection is done under fluoroscopy, dye may be injected into the epidural space followed by a test dose.  
• The patient's blood pressure, pulse, oxygen saturation and respiration are monitored when necessary.
• The steroid is injected into the epidural space.
• The patient is monitored for 30 minutes and then discharged. Typically, the patient is driven home by a spouse or friend.
• The patient is followed up in one week to assess the efficacy of the injection.
