Lumbar Epidural Steroid Injection (ESI)

What is a lumbar epidural steroid injection?

An epidural steroid injection is a procedure in which your doctor injects steroid medication into the epidural space. The epidural space is located inside the bony spinal canal but outside the tube that holds the spinal fluid. It extends from the base of the skull to the base of the spine.

When a steroid (a strong anti-inflammatory medicine) is put into the epidural space, it can reach the spinal discs and nerves, reducing inflammation and relieving pain. The goal of a lumbar epidural steroid injection is to decrease lower back or lower extremity pain caused by one or more compressed or inflamed spinal nerves in the lower back (lumbar spine).

Overview of the epidural steroid injection procedure

Here’s what to expect during an epidural steroid injection procedure:

The steroid usually starts to work two days to two weeks after the injection. The pain relief varies for each individual, from no relief to long-term pain relief. Patients can have up to four steroid injections per year, depending on their other health problems or steroid injections into different areas of the body.

Preparing for the epidural steroid injection

Possible side effects of the steroid

Side effects of steroid injections are usually minimal and go away within one to three days after the procedure. Possible side effects of the steroid include:

After the injection

Remember that your usual pain may go away for a few hours, but after the local anesthetic wears off, it is normal for your pain to return. The full effects of the steroid may take two days to two weeks to work, and its lasting effects vary from person to person. You may also have some temporary discomfort at the puncture site.

Potential risks of epidural steroid injections

The risks of epidural steroid injections are minimal and are similar to any procedure involving a needle placement. These include, but are not limited to:

If your procedure includes sedation
