This form of chronic pain often extends from its source down the arm or leg. When this condition occurs in the leg, it’s often referred to as sciatica.

An epidural steroid injection is performed under the guidance of an X-ray machine to pinpoint an exact position to provide the dose. A small volume of steroid, known as cortisone, is injected parallel to the affected nerve root to provide significant, and lasting pain relief.

The first line of treatment for this pain is often physiotherapy, although sometimes pain persists. Unless a reason for surgery is identified (such as bladder/bowel disturbance or leg weakness) an epidural steroid injection is often considered.

There are multiple technical differences in the way these injections are performed. We commonly inject close to the affected nerve root – also known as a transforaminal injection, or inject at the base of the spine, which is known as a caudal injection.
