ABSTRACT
For the last century, physicians have employed epidural injections to treat low back and radicular pain. Corticosteroids have been included in this technique for the last 50 years. As we continue to refine this technique and study its effects, it has become clear that epidural steroid injections (ESIs) are an important part of the armamentarium for treating low back pain, sciatica, and, to a lesser degree, neck pain.
