Epidural Steroid Injections in San Marcos, TX

What Is an Epidural Steroid Injection and How Does It Work?

An epidural steroid injection (ESI) uses a corticosteroid to target inflammation directly in the affected area. By reducing inflammation around your spinal nerves, these injections help alleviate pain and discomfort. The corticosteroid works by flushing out the proteins that cause swelling, offering relief from the pressure on your nerves.

Targeting Low Back Pain with Lumbar Corticosteroid Injections

Epidural steroid injections are a minimally invasive treatment designed to relieve pain in the back, neck, arms, and legs. The procedure involves injecting corticosteroids into the epidural space, which is located just outside the protective membrane of the spinal cord. Most patients experience significant pain relief lasting several months from a single injection. The primary goal is to reduce discomfort, allowing you to return to your normal activities pain-free.

Different Types of Epidural Steroid Injections

Interlaminar Injection

The most commonly used ESI, this type involves inserting a needle into the back, allowing the steroid to spread across a wider area in the epidural space.

Caudal Injection

Delivered through the sacral hiatus, near the tailbone, this type of injection is placed lower in the back, specifically targeting the bottom of the epidural space.

Transforaminal Injection (Nerve Block)

Often referred to as a “nerve block,” this approach involves placing the needle near the nerve's exit point from the spine. The steroid is delivered into the epidural space from the side, providing more focused relief.
