Epidural Steriod Injection
Epidural steroid injection is a minimally-invasive procedure used to inject a steroid (and often an anesthetic) into the spinal region known as the epidural space. In the spine, the actual nerves, spinal cord, and spinal fluid are contained within a membrane called the dura, and the injection is made into the area just outside this membrane, not within it. The technique is often used to treat chronic low back and leg pain from many causes, and epidural steroid injection is often included as part of a comprehensive treatment and rehabilitation program to treat the underlying causes of the pain.

Say goodbye to back pain...
While epidural spinal injection provides only temporary relief from pain – from one week to a year – it can be very beneficial during acute episodes of back or leg pain, providing enough relief for the patient to participate in stretching or rehabilitation exercises that can provide more permanent relief.
Delivery of the epidural injection is usually performed in a hospital or outpatient setting by experienced interventional radiologists, because placement of the injection in the epidural space is critical, and must be guided by X-ray technology. It is considered a non-surgical, minimally-invasive procedure, and involves precisely injecting an anti-inflammatory steroid, often in conjunction with an anesthetic to reduce inflammation and reduce radiatory pain.
