Treatment Choice - Treatment Choice | Compare Prices | Find Hospital | An epidural injection is delivered into the epidural space of the spine to provide temporary or prolonged relief from pain or inflammation. The epidural space is located outside the dural membrane. Steroids, anesthetics and anti-inflammatory medications are typically delivered in an epidural injection. The injection may reduce pain and swelling in and around the spinal nerve roots, as well as around damaged nerves which in time may heal.<br/>Imaging guidance, such as fluoroscopy or computed tomography (CT or "CAT" scan), may be used to help the doctor place the needle in exactly the right location so the patient can receive maximum benefit from the injection.
