Epidural Injections (ESIs) are a common method of treating inflammation associated with low back related leg pain, or neck related arm pain. In both of these conditions, the spinal nerves become inflamed due to narrowing of the passages where the nerves travel as they pass down or out of the spine.
How Are Epidural Injections Performed?
There are three common methods for delivering steroid into the epidural space. All three approaches entail placing a thin needle into position using fluoroscopic (x-ray) or ultrasound guidance. Prior to the injection of steroid, contrast dye is used to confirm that the medication is traveling into the desired area. Often, local anesthetic is added along with the steroid to provide temporary pain relief.
All three procedures are performed on an outpatient basis, and you can usually return to your pre-injection level of activities the following day.
