Lumbar Epidural Spinal Injection (LESI)

What is LESI?

A lumbar epidural steroid injection (LESI) is a common procedure performed at the pain clinic. It involves accessing the epidural space with a needle and injecting medications (usually steroids) into the space. The epidural space is the space just outside of the spinal cord. When steroids are injected into the space, they will calm down inflamed nerves in the area.

How does it work?

LESI’s provide a highly variable duration of pain relief. Some patients receive only a few days of pain relief while others have their pain never come back. The duration of pain relief from a LESI all depends on how much inflammation is in the area since the steroids injected in the procedure work by reducing inflammation.

What conditions can it treat?

An LESI is mostly used to treat back and leg pain. The conditions they treat includes radiculopathy, radiculitis, spinal stenosis, degenerative disc disease, herniated discs, post-herpetic neuralgia, and others. The procedure takes about 10 minutes and usually does not require any sedation.
