Currently, epidural steroid injections are widely used both in diagnosing and treating neuropathic pain . Lumbar epidural steroid injections, in particular, are performed in the lumbar region of the lower back in order to treat pain that occurs within the lower back and legs. More specifically, corticosteroids are injected into the epidural space surrounding the spinal nerves of the lumbar region. This medication functions to reduce pain and inflammation within the area. The procedure itself is minimally invasive and does not require surgery.
