Targeted Treatment for Sciatica and Lumbar Nerve Root Pain
Pain that travels from the lower back into the buttock, leg, or foot may occur when a lumbar spinal nerve root becomes irritated or inflamed. When the affected nerve can be identified, a lumbar transforaminal epidural steroid injection (TFESI) provides a targeted way to deliver anti-inflammatory medication near that specific nerve root.
Lumbar transforaminal epidural injections are commonly considered for lumbar radiculopathy and sciatica associated with conditions such as lumbar disc herniation or foraminal stenosis.
At TOPS Institute, we provide image-guided lumbar transforaminal epidural steroid injections in Los Angeles and Beverly Hills. Our diagnosis-driven approach focuses on identifying the nerve responsible for a patient’s symptoms and determining whether a targeted epidural injection is appropriate.

What Is a Lumbar Transforaminal Epidural Steroid Injection?
A lumbar transforaminal epidural steroid injection is a minimally invasive procedure that delivers anti-inflammatory medication into the epidural space near a specific lumbar spinal nerve root.
Spinal nerves exit the lumbar spine through openings between adjacent vertebrae called the neural foramina.
The term transforaminal refers to the approach used to access the epidural space through this foraminal region.
By positioning medication near the affected nerve root, a TFESI can provide targeted treatment for inflammation contributing to radiating nerve pain.
The procedure does not remove a herniated disc, reverse arthritis, or permanently widen a narrowed foramen. Its purpose is to address inflammation surrounding an irritated spinal nerve.
What Does a Lumbar Transforaminal Epidural Injection Treat?
A lumbar TFESI is primarily used for radicular pain, meaning pain associated with irritation or inflammation of a spinal nerve root.
Depending on the patient’s diagnosis, the procedure may be considered for:
- Lumbar radiculopathy
- Sciatica
- Lumbar disc herniation
- Foraminal stenosis
- Selected cases of lumbar spinal stenosis
- Degenerative changes affecting a lumbar nerve root
Symptoms may include:
- Shooting leg pain
- Burning pain
- Electric-like sensations
- Numbness
- Tingling
- Pins and needles
- Other nerve-related symptoms
Because the procedure targets a particular nerve root, determining which nerve is responsible for the patient’s symptoms is an important part of treatment planning.
Lumbar Transforaminal Epidural Injection for Sciatica
Sciatica commonly refers to pain traveling from the lower back or buttock into the leg.
A frequent underlying cause is lumbar radiculopathy, which occurs when a lumbar spinal nerve root becomes irritated or compressed.
Depending on which nerve root is affected, symptoms may travel into different areas of the:
- Buttock
- Thigh
- Lower leg
- Foot
- Toes
A lumbar transforaminal epidural steroid injection may be considered when the patient’s symptoms, examination, and imaging suggest inflammation involving a particular lumbar nerve root.

Lumbar Transforaminal Epidural Injection for a Herniated Disc
A lumbar disc herniation can irritate or compress a nearby spinal nerve.
In addition to mechanical pressure, inflammation surrounding the affected nerve root can contribute to radicular pain.
A transforaminal epidural injection delivers corticosteroid medication near the affected nerve root to help reduce this inflammatory component.
The procedure does not physically remove or repair the herniated disc.
Instead, the goal is to reduce nerve inflammation, improve pain, and potentially make rehabilitation and normal activity more manageable.

Lumbar Transforaminal Epidural Injection for Spinal Stenosis
Lumbar spinal stenosis involves narrowing within portions of the lower spine.
When narrowing occurs around the opening through which a spinal nerve exits, it is known as foraminal stenosis.
Foraminal narrowing may irritate or compress an individual nerve root and contribute to lumbar radiculopathy.
For appropriately selected patients, a transforaminal epidural injection may be considered to deliver medication near the affected nerve.
The procedure does not reverse or physically widen the underlying spinal stenosis.

How Does a Lumbar Transforaminal Epidural Steroid Injection Work?
A lumbar TFESI typically uses corticosteroid medication to reduce inflammation around an irritated spinal nerve.
Depending on the procedure, a local anesthetic may also be used.
The medication is delivered into the epidural region near the affected nerve root.
Reducing inflammation may help decrease symptoms such as:
- Radiating leg pain
- Burning discomfort
- Tingling
- Other nerve-related pain
Pain reduction may also help some patients participate more comfortably in physical therapy, exercise, and rehabilitation.
Individual responses vary, and complete or permanent pain relief cannot be guaranteed.
How Is a Lumbar Transforaminal Epidural Injection Performed?
Lumbar transforaminal epidural steroid injections are generally performed as outpatient procedures using image guidance.
The procedure typically involves:
- The patient is positioned to allow access to the lumbar spine.
- The treatment area is cleaned and prepared.
- Local anesthetic may be used to numb the skin and surrounding tissues.
- Using imaging guidance, the physician carefully advances the needle toward the neural foramen associated with the affected nerve.
- Contrast material may be used when appropriate to evaluate needle placement and medication distribution.
- Medication is carefully delivered near the targeted nerve root.
- The needle is removed, and the patient is monitored after the procedure.
The exact approach is individualized according to the patient’s anatomy and affected spinal level.
Why Is Image Guidance Used?
The lumbar spine contains spinal nerves, blood vessels, bones, and other important anatomical structures.
Image guidance allows the physician to visualize spinal anatomy while positioning the needle.
Contrast material may also be used to help confirm appropriate distribution before medication is administered.
This is particularly important with a transforaminal approach because the goal is to precisely access the region surrounding a specific spinal nerve root.
Lumbar Transforaminal vs. Interlaminar Epidural Steroid Injection
Both procedures deliver medication into the lumbar epidural space, but they use different approaches.
Transforaminal Epidural Injection
A transforaminal epidural steroid injection approaches the epidural space through the neural foramen and delivers medication near a specific spinal nerve root.
Interlaminar Epidural Injection
An interlaminar epidural steroid injection enters the epidural space between adjacent vertebral structures and generally allows medication to spread within a broader portion of the epidural space.
Neither approach is automatically better.
The appropriate technique depends on:
- Location of nerve irritation
- Pattern of symptoms
- Imaging findings
- Patient anatomy
- Previous procedures
- Clinical goals

Lumbar Transforaminal vs. Caudal Epidural Injection
A caudal epidural steroid injection enters the epidural space through the sacral hiatus at the base of the spine.
Medication then travels upward within the epidural space.
A transforaminal epidural injection approaches a particular nerve root through the neural foramen.
The primary difference is therefore the route and degree of targeting.
The caudal approach may distribute medication across a broader lower epidural region, while the transforaminal approach is designed to deliver medication near a selected nerve root.

Who Is a Candidate for a Lumbar Transforaminal Epidural Steroid Injection?
A lumbar TFESI may be considered when symptoms and clinical findings suggest irritation of a specific lumbar spinal nerve.
Potential candidates may include patients who:
- Have lumbar radiculopathy or sciatica
- Experience persistent radiating leg pain
- Have a lumbar disc herniation affecting a nerve
- Have foraminal stenosis
- Have selected forms of lumbar spinal stenosis
- Continue to experience symptoms despite conservative treatment
- Have symptoms that interfere with walking, exercise, work, or sleep
A TFESI is generally not intended as a treatment for nonspecific lower back pain without evidence of nerve-root involvement.
How Long Does a Lumbar Transforaminal Epidural Injection Last?
The duration of relief varies.
Some patients may experience meaningful improvement lasting weeks or months, while others may experience shorter or limited relief.
Results depend on factors including:
- Underlying spinal condition
- Severity of nerve inflammation
- Duration of symptoms
- Degree of structural compression
- Response to previous treatment
- Individual patient factors
The procedure is generally used as part of a broader treatment plan rather than as a permanent cure for the underlying spinal condition.
How Quickly Does a Transforaminal Epidural Injection Work?
Some patients notice improvement relatively soon, while the anti-inflammatory effect of the corticosteroid may take several days to become more noticeable.
Temporary soreness or a temporary increase in symptoms may occur after treatment.
Patients should follow the post-procedure instructions provided by their physician.
How Many Lumbar Transforaminal Epidural Injections Can You Have?
The appropriate frequency varies by patient.
Factors considered may include:
- Response to the previous injection
- Duration of improvement
- Underlying diagnosis
- Overall health
- Medication history
- Steroid exposure
- Clinical guidelines
- Treatment goals
Injections should not simply be repeated automatically.
At TOPS Institute, additional treatment is considered according to the patient’s clinical response and ongoing symptoms.
Are Lumbar Transforaminal Epidural Steroid Injections Safe?
Lumbar TFESIs are commonly performed interventional procedures, but all medical procedures have potential risks.
Potential risks and side effects may include:
- Temporary injection-site soreness
- Temporary increase in pain
- Headache
- Bleeding
- Infection
- Medication-related effects
- Allergic reaction
- Nerve injury
- Blood vessel injury
- Other uncommon but potentially serious complications
Certain medications, including blood thinners, and some medical conditions may require additional planning.
Potential risks, benefits, and alternatives should be reviewed before treatment.
What Is Recovery Like?
Lumbar transforaminal epidural steroid injections are generally outpatient procedures.
Patients are typically monitored after the injection before returning home.
Temporary soreness around the injection area may occur.
Specific recommendations regarding activity, exercise, medications, and return to normal activities depend on the individual patient.
When symptoms improve, patients may be better able to participate in rehabilitation, exercise, and other strategies designed to support long-term function.
