Lumbar radiculopathy is irritation or compression of a nerve root in the low back — most commonly L4, L5, or S1. The compressed nerve produces pain, numbness, tingling, and sometimes weakness that radiates down the leg in a specific pattern. While 'sciatica' is often used as a catch-all term, true lumbar radiculopathy has a specific dermatomal pattern that we map carefully on exam.
Also known as: Pinched lumbar nerve, Lumbar nerve root compression, Sciatica (when L5 or S1)
Symptoms of lumbar radiculopathy
- Sharp, shooting, or burning leg pain in a specific stripe down the leg
- Numbness or tingling in the foot, often in a specific toe (big toe = L5, pinky = S1)
- Weakness with heel walking (L5) or toe walking (S1)
- Pain worse with sitting, coughing, or sneezing
- Relief when lying flat with knees bent
Common causes
- Lumbar disc herniation (most common)
- Lumbar spinal stenosis
- Lumbar foraminal narrowing from arthritis
- Spondylolisthesis
- Auto accident, slip and fall, or lifting trauma
How we treat lumbar radiculopathy
We combine multiple disciplines under one roof so you get the right care for your case — not just whatever one provider happens to offer.
Spinal decompression therapy
Lumbar decompression to reduce disc pressure on the affected nerve root — the most effective non-surgical option for disc-related radiculopathy.
Learn more →Chiropractic care
Lumbar adjustments and soft-tissue work to restore mechanics and reduce nerve irritation.
Learn more →Physical therapy
McKenzie exercises, core stabilization, and nerve glides to centralize symptoms and prevent recurrence.
Learn more →Lumbar epidural injections
Transforaminal or interlaminar epidural steroid injections for severe or persistent radicular pain.
Learn more →What to expect on your first visit
- Neurological exam to identify the specific nerve root involved
- Straight-leg-raise and slump tests for nerve tension
- Strength testing and reflexes to grade severity
- MRI review if available — imaging when red flags are present
- Conservative plan with re-eval every 2–4 weeks; injection or surgical referral only when warranted
Frequently asked questions
Is lumbar radiculopathy the same as sciatica?
Sciatica is the common term for radicular pain in the L5 or S1 distribution. Lumbar radiculopathy is the broader medical term and includes higher levels (L1–L4) that produce pain in the front of the thigh or groin.
Can lumbar radiculopathy heal without surgery?
Yes — about 80–90% of patients recover with conservative care. Decompression, chiropractic, PT, and (when needed) epidural injections work well for the vast majority.
When is surgery needed?
Urgent surgery is needed for cauda equina syndrome (saddle numbness, bowel/bladder changes) or rapidly progressive weakness. Otherwise, surgery is considered only after extensive conservative care has failed.
Ready to start treatment?
Same-day appointments available. We accept most major insurance, workers' comp, and personal injury liens.

Sciatica
Sciatica is pain that radiates along the path of the sciatic nerve — from the lower back, through the buttock, and down one leg. It's almost always caused by compression or irritation of a lumbar nerve root, most often from a herniated disc, spinal stenosis, or facet arthritis. The good news: the vast majority of sciatica cases resolve without surgery when treated early with the right combination of decompression, manual therapy, and rehab.
Learn more →Herniated Disc
A herniated disc happens when the soft inner core of a spinal disc pushes through a tear in the tough outer layer, often pressing on a nearby nerve root. It can occur in the cervical (neck), thoracic (mid-back), or lumbar (low back) spine. While the term sounds alarming, most herniated discs respond very well to non-surgical care that combines decompression, chiropractic adjustments, and rehab.
Learn more →Spinal Stenosis
Spinal stenosis is a narrowing of the spinal canal that puts pressure on the spinal cord or nerve roots. It most commonly affects the lumbar (low back) and cervical (neck) regions and is usually age-related. Many patients can manage stenosis effectively with a combination of decompression, manual therapy, targeted exercise, and — when needed — interventional pain procedures.
