An epidural steroid injection is a shot of steroid and numbing medicine that helps relieve pain caused by an irritated or swollen nerve root. The shot is made into the epidural space, which is the space between the spinal cord and the bones in your back (vertebrae).
The amount of pain relief you get from the injection depends on what is causing the nerve to be swollen and irritated and how long the pain lasts. You are more likely to benefit from this injection if your pain comes on strong and suddenly than if you have long-term pain.
