An epidural injection is an injection of medication into the epidural space to temporarily relieve low back and leg pain, and may also be effective in relieving cervical and thoracic pain. This treatment is most effective for treating swelling, pain and inflammation caused by conditions such as:
- Lumbar disc herniation
- Degenerative disc disease
- Lumbar spinal stenosis
- Vertebral compression fractures
- Facet joint or nerve root cysts
- Annular tear
Epidural injections are comprised of cortisone and a local anesthetic or saline solution. These injections work by reducing inflammation and flushing out the particles that cause swelling and pain. Medication is delivered directly to the source of the pain, rather than dispersing it throughout the body as oral painkillers and steroids do.
This form of pain management treatment can be used alone to provide pain relief or as part of a customized rehabilitation program to help the patient perform his/her exercises with less discomfort. Relief from a single injection typically lasts from one week up to one year, depending on the patient’s individual condition.
