epidural steroid injections are most commonly used in situations of radicular pain which is a radiating pain that is transmitted away from the spine by an irritated spinal nerve. irritation of a spinal nerve in the low back (lumbar radiculopathy) causes pain that goes down the leg. epidural injections are also used to treat nerve compression in the neck (cervical spine) referred to as cervical radiculopathy.
