Lumbar Plexus Block: Targeted Nerve Block for Hip, Groin, and Anterior Thigh Pain

A lumbar plexus block is a deep image-guided injection placed near the lumbar plexus, a nerve network that travels through the psoas muscle and supplies important nerve branches to the hip, groin, anterior thigh, medial thigh, and part of the lower extremity.

This block is sometimes called a psoas compartment block. In anesthesia, it is commonly discussed for hip, thigh, and knee surgery pain control. In pain medicine, it may be useful in selected patients when the clinical question involves the femoral nerve, obturator nerve, lateral femoral cutaneous nerve, or broader lumbar plexus pathway.

At SpinePain Solutions, a lumbar plexus block is not treated as a routine injection for all hip, groin, or thigh pain. It is a deeper and more advanced block than many peripheral nerve injections. The key question is specific: is pain being carried through the lumbar plexus or one of its major branches?

This matters because hip, groin, and thigh pain can come from many sources: the lumbar spine, hip joint, SI joint, femoral nerve, obturator nerve, lateral femoral cutaneous nerve, genitofemoral nerve, ilioinguinal nerve, vascular disease, pelvic pathology, muscle injury, or prior surgery.

A lumbar plexus block may be diagnostic, therapeutic, or both. If numbing the lumbar plexus region temporarily improves the familiar pain, the response may help confirm that this nerve pathway is involved. If relief allows better walking, therapy participation, sleep, or movement, the block may also have therapeutic value.

Important: This Is a Deep Plexus Block

A lumbar plexus block is performed near deep anatomy in and around the psoas muscle. This region is close to blood vessels, the retroperitoneal space, the kidney region, lumbar nerve roots, and the epidural space.

Because of that, this block requires careful patient selection, imaging review, medication review, and a clear reason for doing it.

Quick Answer: What Is a Lumbar Plexus Block?

It is a deep nerve block near the lumbar plexus. The lumbar plexus gives rise to nerves that supply the hip, groin, anterior thigh, medial thigh, and parts of the lower extremity.
It may help selected hip, groin, or anterior thigh nerve pain. It is not for every patient with back or leg pain.
It can be diagnostic. Temporary relief may help confirm that the lumbar plexus or one of its branches is involved.
It can be therapeutic. Pain reduction may improve movement, therapy tolerance, sleep, or function in selected patients.
It is different from a lumbar epidural. A lumbar epidural targets nerve roots near the spine. A lumbar plexus block targets a deeper peripheral nerve network in the psoas region.
It is different from a lumbar sympathetic block. Lumbar sympathetic block targets autonomic nerves. Lumbar plexus block targets sensory and motor nerves.
Sometimes a more targeted block is better. Femoral, lateral femoral cutaneous, obturator, genitofemoral, or ilioinguinal blocks may be more appropriate depending on the pain map.

What Is the Lumbar Plexus?

The lumbar plexus is a network of nerves formed from upper lumbar nerve roots. It lies deep within the psoas muscle and gives rise to several important branches that supply the lower abdomen, groin, hip, anterior thigh, medial thigh, and parts of the leg.

Major branches associated with the lumbar plexus include:

Femoral nerve
Obturator nerve
Lateral femoral cutaneous nerve
Iliohypogastric nerve
Ilioinguinal nerve
Genitofemoral nerve

Because these nerves serve different regions, symptoms may vary. One patient may have anterior thigh pain. Another may have groin pain. Another may have hip-region pain or post-surgical nerve pain after hip, pelvic, or abdominal surgery.

The lumbar plexus carries both sensory and motor fibers. That means a block may temporarily reduce pain and sensation, but it may also cause temporary weakness or heaviness in the thigh or leg depending on medication spread.

The Lumbar Plexus Is a Nerve Crossroads

Hip, groin, and thigh pain can travel through several overlapping nerve branches. A lumbar plexus block tests a broader upstream pathway, while smaller nerve blocks test more specific roads.

What Conditions May Benefit From a Lumbar Plexus Block?

A lumbar plexus block may be considered when the pain pattern suggests involvement of the lumbar plexus or one of its major branches and when a broader plexus-level block would help guide treatment.

Possible situations include:

Selected anterior thigh nerve pain
Selected hip or groin nerve pain when lumbar plexus involvement is suspected
Femoral nerve-related pain patterns
Obturator nerve-related medial thigh or hip-region pain patterns
Lateral femoral cutaneous nerve-related thigh pain when broader plexus involvement is suspected
Post-surgical hip, pelvic, or lower abdominal nerve pain
Post-traumatic hip, pelvis, thigh, or femoral nerve irritation
Selected postherpetic neuralgia involving lumbar plexus distributions
Diagnostic clarification when pain overlaps multiple lumbar plexus branches

This block is not usually the first step for ordinary low back pain, classic lumbar radiculopathy, hip arthritis, meralgia paresthetica, or isolated groin nerve pain. In many cases, a more targeted block may answer the question with less risk.

Lumbar Plexus Block vs. Other Lower-Body Nerve Blocks

Several procedures can sound similar. They are not interchangeable. Each one tests a different part of the pain map.

Procedure	Main Target	Typical Question It Answers
Lumbar Plexus Block	Lumbar plexus in or near the psoas muscle	Is a broader lumbar plexus pathway carrying hip, groin, or anterior thigh pain?
Lumbar Epidural Injection	Lumbar nerve roots or epidural space	Is pain coming from disc herniation, stenosis, foraminal narrowing, or lumbar radiculopathy?
Lumbar Sympathetic Block	Sympathetic nervous system	Is pain sympathetically maintained, such as selected CRPS or vascular-type limb pain?
Femoral Nerve Block	Femoral nerve	Is anterior thigh or knee-region pain traveling through the femoral nerve?
Lateral Femoral Cutaneous Nerve Block	Lateral femoral cutaneous nerve	Is burning outer thigh pain from meralgia paresthetica or lateral thigh nerve irritation?
Genitofemoral / Ilioinguinal Blocks	Groin and lower abdominal wall nerves	Is groin, pubic, genital-region, or post-hernia pain coming from a specific groin nerve?

The Block Helps Answer a Question

The key question is not simply “Do you have hip or thigh pain?” The better question is: “Which nerve pathway is carrying the pain, and will blocking that pathway change the plan?”

Who May Benefit From a Lumbar Plexus Block?

A lumbar plexus block may be reasonable when symptoms suggest a lumbar plexus-level pain pathway and when a broader block is more useful than a smaller branch block.

Patients Who May Be Better Candidates

Patients with complex hip, groin, or anterior thigh nerve pain where several lumbar plexus branches may overlap
Patients with post-surgical hip, pelvic, or lower abdominal nerve pain
Patients with post-traumatic femoral, obturator, or lumbar plexus irritation
Patients with anterior thigh pain that does not clearly match lumbar spine imaging
Patients with groin and thigh symptoms that cannot be explained by one small peripheral nerve
Patients who need diagnostic clarification before longer-term nerve treatment is considered
Patients who can carefully track pain relief, numbness, weakness, walking, and functional change after the block

Who May Not Be a Good Candidate?

A lumbar plexus block may not be appropriate when the pain is clearly coming from another source or when the risk profile is too high for a deep plexus procedure.

Patients Who May Not Be Good Candidates

Patients with lumbar disc herniation, stenosis, or radiculopathy clearly explaining symptoms
Patients with isolated meralgia paresthetica where a lateral femoral cutaneous nerve block is more specific
Patients with isolated groin pain better evaluated with genitofemoral, ilioinguinal, or iliohypogastric nerve blocks
Patients with hip arthritis, fracture, infection, or implant problem requiring orthopedic evaluation
Patients with progressive weakness, foot drop, bowel/bladder symptoms, or neurologic decline
Patients with active infection near the injection site
Patients with unsafe anticoagulation status or high bleeding risk
Patients with widespread pain where one deep nerve block is unlikely to answer the main question
Patients expecting one injection to permanently cure all hip, groin, thigh, or leg pain

Hip, Groin, and Thigh Pain Red Flags Need Prompt Evaluation

New or progressive leg weakness
Loss of bowel or bladder control
Saddle numbness
Fever, chills, redness, or concern for infection
Severe pain after trauma, fall, or suspected fracture
Sudden groin pain with inability to bear weight
History of cancer with new severe pelvic, hip, or spine pain
Sudden cold, pale, swollen, or pulseless leg

What Happens During a Lumbar Plexus Block?

The exact procedure depends on the target, anatomy, medical history, and physician judgment. A lumbar plexus block is a deep procedure and is usually performed with imaging and careful monitoring.

Step 1: Evaluation and Target Selection

The physician reviews the pain pattern, neurologic findings, lumbar spine imaging, hip and pelvic history, prior surgery, trauma history, medications, anticoagulation status, and possible competing diagnoses. The goal is to decide whether a lumbar plexus-level block is appropriate or whether a more specific block would be safer and more useful.

Step 2: Positioning and Monitoring

The patient is positioned to allow access to the deep psoas or lumbar plexus target region. Vital signs may be monitored because the procedure involves local anesthetic near a major nerve network.

Step 3: Image-Guided Needle Placement

Fluoroscopy, ultrasound, nerve stimulation, or a combination of techniques may be used depending on the target and anatomy. Because the lumbar plexus is deep, image guidance and careful depth control are especially important.

Step 4: Safety Checks

The physician may use aspiration, contrast when appropriate, nerve stimulation response, incremental injection, and other safety steps to reduce the chance of vascular injection, unintended neuraxial spread, or injection in the wrong tissue plane.

Step 5: Medication Injection

Medication is placed near the lumbar plexus region, not intentionally inside a nerve. The medication may include local anesthetic and other medication depending on the purpose of the block and the patient’s condition.

Step 6: Response and Follow-Up

The patient should track pain relief, numbness pattern, thigh or leg heaviness, walking tolerance, groin pain, hip motion, anterior thigh symptoms, and how long the effect lasts. This information helps guide the next step.

Track the Pain Map Carefully

After a lumbar plexus block, patients should notice whether groin, hip, anterior thigh, medial thigh, or walking-related symptoms improve and whether numbness or weakness appears in the expected region.

Why Precision Matters

The lumbar plexus sits deep in the psoas muscle region. It is not a surface-level nerve block. The target area is close to deep blood vessels, the retroperitoneal space, lumbar spine structures, the kidney region, and the epidural or paravertebral space.

Precision matters because the block must be useful enough to justify its depth and risk. In many patients, a smaller, more targeted nerve block may answer the clinical question with less anatomical turbulence.

Precision may help the physician:

Confirm whether a broader lumbar plexus pathway is involved
Distinguish lumbar plexus pain from lumbar radiculopathy
Distinguish groin nerve pain from femoral or obturator nerve pain
Reduce unnecessary spread to unintended structures
Improve confidence that the block result is meaningful
Decide whether a more specific nerve target should be treated next

Deep Block, Clear Reason

A lumbar plexus block should not be done because the pain map is vague. It should be done because the pain map points to the lumbar plexus strongly enough to justify a deep target.

Lumbar Plexus Block vs. More Targeted Branch Blocks

One of the most important decisions is whether to block the lumbar plexus broadly or to block a smaller branch more specifically.

A broader lumbar plexus block may be useful when symptoms overlap several branches or when the physician needs to test a larger upstream nerve pathway. A smaller branch block may be better when the symptoms fit one nerve more clearly.

Pain Pattern	Possible More Targeted Block	Why It May Be Preferred
Outer thigh burning or numbness	Lateral femoral cutaneous nerve block	More specific for meralgia paresthetica-type symptoms.
Groin, pubic, or genital-region pain	Genitofemoral, ilioinguinal, or iliohypogastric nerve block	More specific for post-hernia or lower abdominal wall/groin nerve pain.
Anterior thigh or knee-region pain	Femoral nerve or saphenous-related block	May test the suspected branch without blocking the entire plexus.
Medial thigh or obturator-region pain	Obturator nerve block	More specific when obturator distribution or hip adductor-related pain is suspected.
Mixed groin, hip, anterior thigh, and medial thigh pain	Lumbar plexus block	May be useful when several lumbar plexus branches overlap and branch-level diagnosis is unclear.

How Long Does Relief Last?

Relief after a lumbar plexus block varies. Some patients feel relief only while the local anesthetic is active. Others may improve longer if the block reduces a pain flare, permits better movement, or helps clarify the treatment plan.

The duration of relief depends on several factors:

Whether the lumbar plexus is truly part of the pain pathway
Whether the correct target was reached
Whether pain is post-surgical, post-traumatic, neuropathic, spine-related, hip-related, or inflammatory
Whether medication spread included the relevant branches
Whether the pain would have been better tested with a smaller branch block
Whether therapy or movement can be restarted during the relief window
Whether another condition remains untreated

A short but strong response can be diagnostically meaningful. Longer relief may be therapeutic. No relief may suggest that the diagnosis, target, or pain generator needs to be reconsidered.

What If the Lumbar Plexus Block Helps?

If a lumbar plexus block helps, the result may suggest that the lumbar plexus or one of its major branches is part of the pain pathway. The next step depends on the amount of relief, how long it lasted, the numbness pattern, and whether function improved.

Possible next steps may include:

Observation if relief is strong and lasting
Physical therapy or gait work during the pain-relief window
Medication adjustment for nerve pain
More specific branch-level nerve block if the response helps localize the pain
Femoral, obturator, lateral femoral cutaneous, genitofemoral, or ilioinguinal nerve evaluation when appropriate
Hip or orthopedic evaluation if structural disease remains important
Lumbar spine evaluation if radiculopathy remains possible
Peripheral nerve stimulation in selected chronic focal nerve pain patterns
Further diagnostic work if multiple pain generators remain possible

Relief Gives Direction

A helpful lumbar plexus block does not always mean the entire plexus is the only pain source. It may simply show that one or more lumbar plexus branches are important enough to guide the next step.

What If the Block Does Not Help?

If a lumbar plexus block does not help, the information can still be useful. It may mean the lumbar plexus is not the main pain pathway, the pain is coming from the spine, hip, pelvis, SI joint, vascular system, or a more distal peripheral nerve, or the block target did not match the painful region.

When the block does not help, the plan may shift toward:

Rechecking the pain map and neurologic exam
Reviewing lumbar spine imaging for radiculopathy or stenosis
Considering hip joint, labral, tendon, or replacement-related causes
Considering SI joint or pelvic sources
Considering genitofemoral, ilioinguinal, obturator, femoral, or lateral femoral cutaneous nerve blocks
Considering vascular, abdominal, pelvic, urologic, or gynecologic causes when appropriate
Considering EMG/NCS when nerve localization remains unclear

A Negative Block Is Still Information

If the familiar hip, groin, or thigh pain does not improve after a properly performed lumbar plexus block, the diagnosis may need to move beyond the lumbar plexus pathway.

Risks and Side Effects

Lumbar plexus block can be helpful in selected patients, but it is a deep plexus procedure and carries different risks than superficial nerve blocks. Risks depend on the target, medication, patient anatomy, anticoagulation status, medical history, and imaging method.

Possible Risks and Side Effects Include:

Temporary soreness at the injection site
Bruising or bleeding
Temporary numbness, warmth, heaviness, or weakness in the thigh or leg
Temporary difficulty walking while the leg is numb or weak
Temporary increase in pain
Infection, uncommon but possible
Nerve irritation or nerve injury, uncommon but important
Allergic reaction to medication or contrast, uncommon but possible
Local anesthetic side effects or systemic toxicity
Vascular puncture or hematoma
Psoas or retroperitoneal hematoma
Epidural, intrathecal, or unintended neuraxial spread
Low blood pressure or urinary difficulty if neuraxial spread occurs
Kidney, ureter, bowel, or retroperitoneal structure injury, uncommon but important
Fall risk while the leg is numb or weak
Failure to improve

Patients taking blood thinners or patients with bleeding disorders, infection, medication allergies, kidney issues, complex spine or pelvic anatomy, prior surgery, or progressive neurologic symptoms should discuss risks carefully before the procedure.

Bleeding Risk Matters More Here

The lumbar plexus region is deep and not easily compressed from the outside. Blood thinner management and bleeding risk must be handled carefully before this procedure.

Recovery After a Lumbar Plexus Block

Most patients are monitored after a lumbar plexus block before going home. Some patients notice temporary numbness, warmth, heaviness, or weakness in the thigh or leg depending on medication spread.

Patients must be careful while the leg is numb or weak. A painless leg can still buckle, stumble, or be injured by overuse.

General Recovery Tips

Track pain relief during the first few hours after the block.
Notice which regions become numb: groin, hip, anterior thigh, medial thigh, or knee region.
Use fall precautions until strength and sensation return.
Avoid driving until numbness, heaviness, or weakness has resolved and instructions allow it.
Avoid heavy activity, stairs, or aggressive exercise immediately after the procedure.
Do not overuse the leg just because pain is temporarily reduced.
Call the office if symptoms are severe, worsening, or unusual.

If the block is diagnostic, the early response is especially important. Patients should write down how much relief occurred, where numbness occurred, how long it lasted, and whether walking, hip motion, sitting, standing, or therapy tolerance improved.

Do Not Waste the Diagnostic Window

Track the pain map carefully: groin, hip, anterior thigh, medial thigh, knee region, walking, stairs, weakness, numbness, and movement. That map helps interpret the block.

How to Prepare for the Procedure

Preparation depends on the patient’s medical history, medications, planned target, imaging method, and whether sedation is used.

Before the Procedure

Tell the physician about blood thinners, aspirin, anti-inflammatory medications, and supplements.
Report infection, fever, antibiotic use, or recent illness.
Tell the physician about medication allergy, contrast allergy, latex allergy, or prior reaction to injections.
Tell the physician about kidney disease, vascular disease, bleeding disorders, neurologic disease, or prior retroperitoneal bleeding.
Tell the physician about prior lumbar spine surgery, hip surgery, pelvic surgery, hernia repair, trauma, or nerve injury.
Bring or review relevant lumbar spine, hip, pelvic, or nerve testing if available.
Ask whether blood thinners must be held and when they can be restarted.
Ask whether you need a driver, especially if sedation is planned or leg weakness is expected.
Ask exactly what symptoms and activities to track after the block.

Cost, Insurance, and Coverage

Insurance coverage for lumbar plexus block depends on the diagnosis, payer policy, documentation, medical necessity, medication used, image guidance, and whether prior authorization is required.

Coverage may differ depending on whether the block is performed for diagnostic pain evaluation, post-surgical pain, trauma-related pain, postherpetic neuralgia, or another indication.

Patients should ask:

Is the lumbar plexus block covered by my insurance?
Is prior authorization required?
What diagnosis is being used?
Is the block diagnostic, therapeutic, or both?
Will fluoroscopy, ultrasound, nerve stimulation, or contrast be used?
Could a more targeted nerve block be safer or more specific?
Do I need to hold blood thinners?
Will sedation be used?
What are my out-of-pocket costs?
What happens if the block helps?
What happens if it does not help?

For treatments that are not covered or are self-pay, our office can discuss payment options. For eligible patients, CareCredit financing may be available depending on approval and available terms.

Questions to Ask Before a Lumbar Plexus Block

Before the block, patients should understand what nerve pathway is being tested and why a deep plexus block is being chosen instead of a more targeted nerve block.

Helpful Questions Include:

Do my symptoms suggest lumbar plexus involvement?
Could this pain be coming from my lumbar spine, hip joint, SI joint, pelvis, or vascular system instead?
Would a femoral, obturator, lateral femoral cutaneous, genitofemoral, or ilioinguinal block be more specific?
Is this block diagnostic, therapeutic, or both?
What region should become numb if the block works?
Will fluoroscopy, ultrasound, nerve stimulation, or contrast be used?
What medication will be injected?
How much relief would count as a positive response?
How long should relief last?
What should I track after the block?
What are the bleeding risks in my case?
What are the risks for my specific anatomy and medical history?
What are the next steps if the block helps?
What are the next steps if the block does not help?

The Best Question Before the Block

Ask: “Why are we testing the lumbar plexus broadly instead of a smaller branch nerve?” If the answer is clear, the block has a purpose.

Lumbar plexus block is part of a broader nerve pain care map. Patients with overlapping hip, groin, thigh, pelvic, or spine symptoms may also benefit from related topics.

Frequently Asked Questions About Lumbar Plexus Block

What is a lumbar plexus block?

A lumbar plexus block is a deep nerve block placed near the lumbar plexus, a nerve network in the psoas region that supplies branches to the hip, groin, anterior thigh, medial thigh, and parts of the lower extremity.

Is lumbar plexus block the same as a psoas compartment block?

The terms are often used closely together. A psoas compartment block refers to targeting the lumbar plexus region in or near the psoas muscle compartment.

What does a lumbar plexus block treat?

It may be considered for selected hip, groin, anterior thigh, femoral, obturator, lateral femoral cutaneous, post-surgical, post-traumatic, or postherpetic pain patterns when lumbar plexus involvement is suspected.

Is lumbar plexus block used for ordinary low back pain?

Usually no. Ordinary low back pain is more often evaluated through spine, facet, SI joint, disc, muscle, or radicular pathways. Lumbar plexus block is used when the pain map suggests lumbar plexus or branch nerve involvement.

Is lumbar plexus block the same as a lumbar epidural?

No. A lumbar epidural targets nerve roots or the epidural space near the spine. A lumbar plexus block targets a deeper peripheral nerve network in the psoas region.

Is lumbar plexus block the same as a lumbar sympathetic block?

No. A lumbar sympathetic block targets autonomic sympathetic nerves. A lumbar plexus block targets sensory and motor nerves of the lumbar plexus.

Why not just block a smaller nerve?

Sometimes a smaller branch block is better. Femoral, obturator, lateral femoral cutaneous, genitofemoral, ilioinguinal, or iliohypogastric blocks may be more specific when the pain clearly fits one nerve. Lumbar plexus block may be considered when several branches overlap or a broader diagnostic question needs to be answered.

Will my leg go numb or weak?

It may. Because the lumbar plexus contains sensory and motor fibers, temporary thigh or leg numbness, heaviness, or weakness can occur depending on medication spread.

Is image guidance used?

Image guidance, nerve stimulation, contrast, or a combination of techniques may be used depending on the target and physician judgment. Because the lumbar plexus is deep, careful guidance and depth control are important.

How does the block work?

The block places medication near the lumbar plexus region. Local anesthetic may temporarily numb the nerve pathway and reduce pain signaling. The response helps guide diagnosis and treatment planning.

Is the block diagnostic or therapeutic?

It can be both. If the block temporarily relieves the familiar pain, it may help confirm that the lumbar plexus or one of its branches is involved. If relief improves movement, sleep, walking, or therapy tolerance, it may also have therapeutic value.

How long does relief last?

Relief varies. Some patients improve only while the local anesthetic is active. Others may improve longer if the block reduces a pain flare or allows better movement, therapy, or function.

What if the block helps only briefly?

A short but strong response may still be diagnostically meaningful. It may suggest that the lumbar plexus pathway is involved, even if longer-term treatment is needed.

What if the block does not help?

If the block does not help, the lumbar plexus may not be the main pain pathway, the target may not match the painful region, or symptoms may be coming from the lumbar spine, hip joint, SI joint, pelvis, vascular system, or a more specific peripheral nerve.

What are the risks?

Risks may include soreness, bruising, bleeding, infection, temporary numbness or weakness, pain flare, nerve irritation or injury, allergic reaction, local anesthetic side effects or toxicity, vascular puncture, psoas or retroperitoneal hematoma, epidural or intrathecal spread, low blood pressure, urinary difficulty, kidney or retroperitoneal structure injury, fall risk, and failure to improve.

Why do blood thinners matter?

The lumbar plexus region is deep and not easily compressed if bleeding occurs. Patients taking blood thinners or patients with bleeding disorders need careful medication review before the procedure.

Can the block be repeated?

It may be repeated in selected cases when the first block provides meaningful relief and the diagnosis supports repeating treatment. Repeat blocks should have a clear purpose and should not continue indefinitely without benefit.

What are the next steps if the block works?

Next steps may include therapy, medication adjustment, more targeted branch-level nerve evaluation, hip or spine evaluation, repeat block in selected cases, peripheral nerve stimulation in selected chronic focal pain patterns, or further diagnostic work.

Is this nerve block covered by insurance?

Coverage depends on the diagnosis, payer policy, medical necessity, documentation, medication used, image guidance, and whether prior authorization is required.

Because it is deep, the block requires careful patient selection and risk review.
In many cases, a more targeted branch block may be safer and more specific.
Temporary thigh or leg numbness, heaviness, or weakness can occur.
Bleeding risk matters because the psoas and retroperitoneal region are not easily compressed.
A short but strong response can be diagnostically meaningful.
No relief may mean the diagnosis, target, or pain pathway needs to be reconsidered.
The best use of the block is to clarify the nerve map and guide the next step.

Is Your Hip, Groin, or Thigh Pain Coming From the Lumbar Plexus?

Hip, groin, and thigh pain can come from the spine, hip joint, SI joint, pelvis, femoral nerve, obturator nerve, lateral femoral cutaneous nerve, genitofemoral nerve, ilioinguinal nerve, or lumbar plexus.

At SpinePain Solutions, we evaluate the pain map, neurologic findings, imaging, prior surgery, medication risks, and treatment goals to decide whether lumbar plexus block or a more targeted nerve block makes sense.
