Epidural Steroid Injections
Epidural Steroid Injections for Spine Pain and Nerve Compression in New Jersey.
Epidural steroid injections are one of the most commonly performed and most effective non-surgical treatments for spine pain involving nerve root compression or irritation. They are used for a wide range of spinal conditions, from herniated disc causing sciatica to spinal stenosis causing leg cramping and heaviness with walking, and they occupy a central place in the non-surgical management of spine pain because of their ability to provide targeted, meaningful relief without the risks and recovery of surgery.
The basic principle behind an epidural steroid injection is straightforward. When a nerve root in the spine is compressed or irritated, whether by a herniated disc, bone spur, thickened ligament, or narrowed foramen, the nerve and the surrounding tissues become inflamed. That inflammation amplifies the pain signal the nerve sends, turning what might be mechanical compression into the burning, electric, shooting pain that patients with sciatica and radiculopathy describe. Delivering a powerful anti-inflammatory steroid medication directly into the epidural space surrounding the affected nerve root reduces that inflammation at its source, which reduces the pain signal, often substantially.
What distinguishes a well-performed epidural steroid injection from a poorly performed one is the accuracy of the medication delivery. An injection that places the steroid in the general vicinity of the affected nerve may provide some relief. An injection that places the steroid precisely at the level and side of the compressed nerve root, confirmed under live fluoroscopic imaging, provides targeted relief that is more likely to be meaningful and more likely to last.
Rishi N. Sheth, MD performs all epidural steroid injections at Spine Care New Jersey under fluoroscopic guidance, using real-time X-ray imaging to confirm needle placement before any medication is delivered. His background as a fellowship-trained spine neurosurgeon means that every injection is performed with a precise understanding of the anatomy involved and the specific nerve root being targeted.
Different Injection Approaches for Different Pain Patterns and Spinal Conditions.
Not all epidural steroid injections are performed the same way. The approach used depends on the specific condition being treated, the level and location of nerve root compression, and the pattern of the patient's symptoms. Understanding the differences helps patients know what to expect and why a particular approach was recommended for their situation.
Interlaminar Epidural Steroid Injection
The interlaminar approach accesses the epidural space from the back of the spine, through the space between two adjacent laminae. The needle is directed toward the central epidural space and the steroid bathes the area broadly, reaching nerve roots on both sides at and near the injection level. This approach is most appropriate when the source of pain is not precisely lateralized to one side or when bilateral symptoms are present. It is a widely used and well-established technique.
Transforaminal Epidural Steroid Injection
The transforaminal approach, also called a selective nerve root block, targets the specific foramen through which the symptomatic nerve root exits the spine. The needle is placed directly at the entry point of that foramen under fluoroscopic guidance, and the steroid is delivered precisely around the target nerve root. This approach provides more targeted medication delivery than the interlaminar technique and is particularly effective when symptoms are clearly unilateral and imaging confirms nerve root compression at a specific level. Rishi N. Sheth, MD uses this approach for patients with well-localized radicular symptoms corresponding to a clearly identified level on MRI.
Caudal Epidural Steroid Injection
The caudal approach enters the epidural space through the sacral hiatus, an opening at the base of the sacrum. Medication placed here can flow upward into the lower lumbar epidural space and is used for patients with lower lumbar and sacral nerve root pain, particularly those with prior lumbar surgery where the more direct approaches may be altered by postoperative scarring. It is also used for patients with bilateral lower extremity symptoms from lower lumbar stenosis.
Cervical Epidural Steroid Injection
Cervical epidural injections target the epidural space of the cervical spine and are used for patients with neck pain combined with arm pain, numbness, or weakness from a cervical herniated disc or cervical foraminal stenosis. The anatomy of the cervical spine requires particular care and experience, and cervical epidural injections are best performed by a physician with specific training in the cervical spine. Dr. Sheth's neurosurgical training and deep familiarity with cervical anatomy make him well suited to perform these injections safely and effectively.
The Spine Conditions That Respond Best to Epidural Steroid Injections.
Epidural steroid injections are not appropriate for all causes of back or neck pain. They are specifically designed to address pain that is driven by nerve root inflammation and compression. Understanding which conditions respond best helps set realistic expectations before the procedure.
Lumbar herniated disc
Lumbar herniated disc with sciatica is one of the most common and most responsive indications for epidural steroid injection. When a herniated lumbar disc compresses a nerve root and produces radiating leg pain, targeted epidural steroid delivery around the inflamed nerve root can produce significant and rapid reduction in the leg pain. For many patients with acute disc herniation causing severe sciatica, a well-timed ESI can provide enough relief to avoid surgery while the disc heals naturally.
Lumbar spinal stenosis
Lumbar spinal stenosis causing neurogenic claudication responds to epidural steroid injections when the claudication is driven by nerve root inflammation within a narrowed spinal canal. The steroid reduces the inflammatory component of the nerve irritation, which can meaningfully improve walking tolerance and reduce leg pain even when the structural narrowing itself remains unchanged.
Cervical radiculopathy
Cervical radiculopathy from a cervical herniated disc or foraminal stenosis causing arm pain, numbness, and tingling responds well to cervical epidural steroid injections, particularly when the symptoms are acute or subacute and the degree of nerve root compression is not severe enough to cause progressive neurological deficit.
Degenerative disc disease
Degenerative disc disease that produces radicular symptoms from disc space narrowing and foraminal compromise is another indication where epidural steroid injections can provide meaningful relief as part of a comprehensive conservative treatment plan.
Postoperative nerve root pain following spine surgery, where persistent nerve root irritation continues despite adequate surgical decompression, is also a situation where epidural steroid injections serve an important role in the ongoing management of the patient’s symptoms.
What Happens Before, During, and After Your Epidural Steroid Injection.
Many patients approach their first epidural steroid injection with a mixture of hope and apprehension. Knowing what the procedure actually involves removes most of the anxiety.
Before the Procedure
At Spine Care New Jersey, every epidural steroid injection is preceded by a thorough clinical evaluation during which Rishi N. Sheth, MD reviews the patient's imaging, confirms the diagnosis, and selects the most appropriate injection approach for that patient's specific pain pattern and anatomy. Patients are asked to inform Dr. Sheth of any blood thinning medications they take, as these may need to be temporarily held before the procedure. Most patients do not need to fast before an epidural steroid injection, though they are advised to arrange for someone to drive them home afterward.
During the Procedure
The procedure is performed with the patient lying on a procedure table in a position that provides the best fluoroscopic access to the injection site. The skin over the injection area is cleaned and a local anesthetic is applied to numb the superficial tissues. Dr. Sheth then carefully advances the injection needle toward the target location under continuous fluoroscopic guidance, confirming the position at each step before advancing further. Contrast dye is injected first to confirm that the needle tip is correctly positioned in the epidural space and that the medication will flow to the intended target before the steroid is delivered. Patients may feel pressure during the procedure but significant pain during a well-performed injection is uncommon.
The procedure typically takes between 15 and 30 minutes from start to finish. Patients rest briefly in the recovery area and are discharged home once they are comfortable and their vital signs are stable.
After the Procedure
Most patients experience some temporary increase in their usual pain in the first 24 to 48 hours after the injection, which reflects the small volume of fluid added to the epidural space and any local irritation from the needle. This is normal and resolves quickly. The therapeutic benefit of the steroid typically begins to develop over the first three to seven days after the injection and reaches its maximum effect at approximately two weeks.
Patients are advised to avoid heavy lifting and strenuous activity on the day of the procedure. Normal daily activities can typically resume the following day. Physical therapy, if prescribed alongside the injection, usually continues through the post-injection period and benefits from the pain relief the injection provides.
What Epidural Steroid Injections Can and Cannot Do.
This is a conversation Rishi N. Sheth, MD has with every patient before an epidural steroid injection, because setting honest expectations is one of the most important things a physician can do for their patients.
Epidural steroid injections are anti-inflammatory treatments. They reduce nerve root inflammation. They can provide significant and sometimes dramatic relief from the radiating pain, numbness, and tingling that inflammation-driven nerve compression produces. For many patients, they provide enough relief to allow full participation in physical therapy, to avoid surgery, or to bridge the time until the underlying condition improves naturally.
What they do not do is fix a structural problem. A herniated disc is still herniated after an epidural steroid injection. A narrowed spinal canal from stenosis is still narrowed. Bone spurs are still present. The injection addresses the inflammatory component of the nerve pain, not the structural cause. This is why the relief from an epidural steroid injection, when it works, is meaningful but typically temporary. Most patients experience relief lasting anywhere from several weeks to several months. Some experience relief that lasts considerably longer, particularly those whose underlying condition has a significant inflammatory component or those who use the relief period to make lasting improvements through physical therapy and lifestyle modification.
For patients whose pain is driven entirely by structural compression with very little inflammatory component, such as a nerve root that is mechanically pinched by a bone spur with no surrounding inflammation, the response to epidural steroid injection may be limited. Identifying these patients through careful clinical evaluation before injection is part of what Rishi N. Sheth, MD does to avoid exposing patients to a procedure that is unlikely to benefit them.
A single injection can be repeated if it provides meaningful but temporary relief, with most physicians recommending no more than three injections in a twelve-month period to limit the systemic effects of repeated steroid exposure. If repeated injections fail to provide adequate benefit, or if the duration of relief progressively shortens, that is a clinical signal that a different treatment approach is warranted.
Conservative Care That Actually Works, Overseen by a Spine Neurosurgeon Who Knows When It Is Enough.
One of the most valuable things a fellowship-trained spine neurosurgeon can offer a patient with a spine condition is something that might seem counterintuitive. The ability to tell them honestly that they do not need surgery yet, and to design a conservative treatment plan that is genuinely likely to help them avoid it.
This requires exactly the expertise that surgical training provides. You have to know what surgery can and cannot accomplish to know when it is and is not necessary. A spine surgeon who only offers surgery is not serving their patients well. A spine surgeon who understands the full treatment spectrum, knows when conservative care is the right tool, and can design and oversee that care with the same rigor they bring to surgical planning, that is what comprehensive spine care looks like.
At Spine Care New Jersey, every patient who can reasonably be managed without surgery is offered the most thoughtfully designed and closely monitored conservative treatment plan that Dr. Sheth can provide. Physical therapy is at the center of that plan for the majority of patients. It is prescribed specifically, monitored consistently, and adjusted based on real outcomes rather than left to run its course and hope for the best.
For patients who ultimately do need surgery after a genuine trial of conservative care, they arrive at that decision with the confidence of knowing that every appropriate non-surgical option was genuinely tried. That confidence is worth something, and it is something Rishi N. Sheth, MD provides to every patient who comes through the door at Spine Care New Jersey.
Common Questions About Epidural Steroid Injections at Spine Care New Jersey.
The most common reasons for an epidural steroid injection are a herniated lumbar disc causing sciatica, lumbar spinal stenosis causing leg pain and cramping with walking, cervical herniated disc causing arm pain and numbness, and foraminal stenosis causing radicular nerve pain. ESI is specifically designed for pain driven by nerve root inflammation and compression. It reduces the inflammatory component of the nerve irritation, providing meaningful relief that allows patients to participate in physical therapy and in many cases avoid surgical intervention.
The duration of relief from an epidural steroid injection varies considerably between patients. Most experience meaningful relief beginning three to seven days after the injection,
with maximum effect at approximately two weeks. The duration of relief typically ranges from several weeks to several months. Some patients experience relief lasting six months or longer, particularly those who combine the injection with active physical therapy during the relief period. If relief is meaningful but temporary, the injection can be repeated, with most physicians recommending no more than three in a twelve-month period.
Before an epidural steroid injection, ask your physician whether imaging confirms that nerve root inflammation is likely the primary driver of your pain, what approach will be used and why, whether fluoroscopic guidance will be used to confirm needle placement, what you should realistically expect in terms of degree and duration of relief, how many injections are appropriate
if the first one helps, and what the next step is if injections do not provide adequate benefit. Rishi N. Sheth, MD discusses all of these questions during the pre-procedure consultation at Spine Care New Jersey.
