Epidural Steroid Injection
Epidural Steroid Injections (ESIs) can relieve pain in the lower back and legs, as well as reducing numbness and weakness caused by inflamed nerves in the spine. These injections are delivered in the epidural space around the spinal cord.
The procedure may consist of injecting several medications into the epidural space, including a contrast material to visualize spread within the epidural space, a local anesthetic to reduce pain, and cortisone to reduce inflammation of the nerves.
Caudal and lumbar epidural steroid injections are used to treat lower back, buttock, and leg pain. Thoracic epidural steroid injections treat mid-back pain. Cervical epidural steroid injections treat neck, shoulder and arm pain.
