An epidural injection can provide temporary or prolonged relief from pain or inflammation in the spine or extremities. It is one of many methods use to relieve pain, along with physical therapy, oral medications and surgery if a patient is not responding to conservative treatments.
An epidural injection may be performed to alleviate pain caused by:
• A herniated or bulging disk that impinges nerves causing pain
• Spinal stenosis
• Post-operative “failed back” surgery syndromes (chronic back or leg pain after spinal surgery)
• Other injuries to spinal nerves, vertebrae and surrounding tissues
• Bone spurs
Imaging guidance, such as fluoroscopy or computed tomography (CT) , may be used to place the needle into the right location for maximum benefit. The injection may also help confirm the exact site of the pain generator.
