What is an Epidural Steroid Injection and How Does it Work?

An epidural steroid injection (ESI) includes a corticosteroid. All epidural injections, such as corticosteroid injections, help by reducing inflammation when delivered directly into a painful area. They work by flushing away the proteins on your spinal nerves that cause swelling.

An epidural steroid injection is a minimally invasive procedure that helps reduce back, neck, arm, and leg pain. It works by delivering corticosteroid injections to the epidural space, a fat-filled area just outside the dural sac in your lower spinal cord. One corticosteroid injection usually provides pain relief for a few months. The goal of an epidural steroid injection is to diminish pain so that you can enjoy your favorite activities.

What Do Epidural Steroid Injections Treat?

Patients with pain in the neck, arm, low back, or leg may benefit from epidural steroid injections. Specifically, those with the following conditions:

What to Expect From The Epidural Steroid Injection Process

Epidural steroid shots are a quick, non-invasive treatment. They involve cleaning and numbing the injection area and the injection itself. Most patients do not require an anesthetic, but sedation is available when needed.

Regardless, make arrangements to have someone drive you home from your Austin pain center the day of the injection, as you shouldn’t drive or do any rigorous activity for 24 hours after treatment.

Types of Epidural Steroid Injections

Interlaminar Injection

This is the most common type of ESI and is commonly just called an epidural injection. A needle is inserted into the back of the epidural space and delivers the steroid over a wider area.

Caudal Injection

The caudal injection delivers the steroid through the sacral hiatus, a small boney opening just above the tailbone. The needle placement for this approach is lower on the back, at the very bottom of the epidural space.

Transforaminal Injection (Nerve Block)

A transforaminal injection is often referred to as a “nerve block”, as the needle is placed near the nerve where it exits the spine. Medication is delivered here and moves into the epidural space from the side, allowing for a more concentrated delivery of the steroid.

The steroid takes two to three days to start to affect most people, peaking after approximately two weeks. Consequently, it can take a while before you feel a reduction in your pain. You can expect to feel some degree of pain relief from a corticosteroid injection for about three months.

How painful is a lumbar epidural steroid injection?

arrow icon

Most people describe the most painful part of an ESI as a temporary stinging or burning sensation at the site of the injection. If you feel anything more than a slight pressure, an additional local anesthetic can be used.

Why would the pain be worse after an epidural steroid injection?

arrow icon

Although rare, some patients may experience an increase in their usual pain for several days following the procedure. This pain is generally mild and resolves itself within a few days. Epidural steroid injections are a low risk, useful, non-surgical pain relief method.
