Epidural steroid injections are one of the most common treatments for spine-related pain caused by nerve compression. They deliver anti-inflammatory medication directly to the area around the spinal nerves, reducing inflammation and providing relief from pain that radiates into the arms or legs.

How Epidural Steroid Injections Work

The epidural space is the area surrounding the spinal cord and nerve roots. When a disc herniation, bone spur, or spinal stenosis compresses a nerve, it causes inflammation that leads to pain, numbness, or weakness. An epidural steroid injection places corticosteroid medication into this space to reduce inflammation and calm the irritated nerve.

The injection is performed using fluoroscopic (X-ray) guidance to ensure accurate needle placement. A small amount of contrast dye confirms the medication will reach the correct location before the steroid is injected.

Types of Epidural Injections

Interlaminar epidural injection approaches the epidural space from the back of the spine, between the lamina. This delivers medication over a broader area.

Transforaminal epidural injection targets a specific nerve root by approaching through the foramen, the opening where the nerve exits the spine. This provides more focused delivery to a single nerve.

The approach used depends on the location of nerve compression and your specific condition.

Conditions Treated

Epidural steroid injections are commonly used for cervical radiculopathy, lumbar radiculopathy, herniated discs, spinal stenosis, and degenerative disc disease with nerve involvement. They are most effective when imaging confirms nerve compression that correlates with your symptoms.

What to Expect

The procedure takes approximately 15 to 30 minutes. You will lie face down and the skin is numbed with local anesthetic. Most patients feel pressure but minimal pain during the injection. You will be monitored briefly afterward and can typically go home the same day.

Some patients experience temporary soreness at the injection site. Pain relief may begin within a few days, though it can take up to two weeks for full effect. The duration of relief varies, lasting weeks to months depending on the underlying condition.

Risks and Limitations

Epidural steroid injections are generally safe. Uncommon risks include infection, bleeding, headache, and temporary increases in blood sugar for diabetic patients. Serious complications are rare.

These injections are not a cure. They reduce inflammation and can provide a window of relief that can allow physical therapy and natural healing to occur. Some patients require a series of injections, while others experience lasting relief from a single treatment.https://neckandbacks.com/#contact
