A lumbar epidural injection is a minimally invasive procedure used to alleviate pain and inflammation in the lumbar (lower back) region of the spine. During the procedure, a corticosteroid medication is injected into the epidural space, which surrounds the protective covering (dura) of the spinal cord and nerve roots in the lumbar spine. This medication helps reduce inflammation and may provide relief from symptoms such as lower back pain, leg pain, and numbness or tingling caused by conditions like herniated discs, spinal stenosis, or nerve compression.

Lumbar epidural injections are often considered as part of non-operative management for lumbar spine disorders before considering surgical options. They can provide temporary relief and may be repeated as needed for ongoing symptom management. The procedure is typically performed under fluoroscopic or ultrasound guidance to ensure accurate placement of the medication.
