Pain Management
An epidural injection is an injection of medication into the space around the spinal cord, also known as the epidural space, to provide temporary or prolonged relief from pain or inflammation. The epidural space is the outermost part of the spinal canal. 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. (radiologyinfo.org)
Epidural injections can be performed bilaterally (left or right) and on various levels (higher or lower), with the most common being cervical and lumbar.
