Lumbar Transforaminal Epidural Steroid Injection

A Lumbar Epidural Steroid Injection (LESI) is a common and highly effective treatment for patients suffering from chronic lower back and leg pain. This procedure involves injecting a combination of a local anesthetic and a powerful anti-inflammatory corticosteroid into the epidural space—the area surrounding the spinal nerves. By targeting the specific site of inflammation caused by conditions like herniated discs, spinal stenosis, or degenerative disc disease, LESIs work to “flush out” inflammatory proteins that cause nerve irritation. This results in reduced swelling, significant pain relief, and improved physical function, often helping patients avoid the need for more invasive surgical interventions.
