Lumbar radiculopathy is something I see all the time in my practice, and it’s actually one of the most common reasons people end up seeing a surgeon. About 3% to 5% of the population will deal with it at some point in their lives.
Men usually notice symptoms in their 40s, while women tend to feel it a little later, often in their 50s or 60s.
When that happens, it’s common to feel back pain paired with sharp, burning, or “electric” sensations radiating down your leg, sometimes one side, sometimes both.
Here at The Disc Chiropractic, I take a hands-on, evidence-based approach.
My goal is always the same: help you get back to your daily life without pain, prevent flare-ups, and address the underlying cause instead of just masking symptoms with medication.
What Is Spinal Radiculopathy?
Spinal radiculopathy is essentially what happens when one of the nerves branching off your spine gets irritated or compressed.
When this occurs, it sends abnormal signals down the nerve that your brain interprets as pain, tingling, numbness, or weakness.
In the lower back, this is often called lumbosacral radiculopathy, and you might know it as sciatica.
In the lumbar spine, radiculopathy often follows predictable patterns based on the nerve root involved:
- L1 nerve root – Pain or discomfort is typically felt in the groin area. Weakness may affect your hip flexors, but reflexes are usually normal.
- L2 nerve root – Pain can appear in the front of the thigh, sometimes accompanied by weakness in hip flexion. Reflexes remain largely unchanged.
- L3 nerve root – Discomfort radiates down the front of the thigh. You may notice weakness in your hip flexors and knee extension, and your knee-jerk reflex might be reduced or absent.
- L4 nerve root – Pain often travels along the inner lower leg and into the foot. Weakness can appear in your knee extension and ankle dorsiflexion, and the knee-jerk reflex may be diminished.
- L5 nerve root – Discomfort typically follows the outside of the leg down to the top of the foot and big toe. You might experience weakness when lifting your big toe (hallux extension) or pointing your foot down (plantarflexion). Reflexes at the ankle can also be reduced.
- S1 nerve root – Pain often runs along the outside of the foot and heel. Weakness can occur in ankle plantarflexion and foot eversion, with reduced or absent Achilles reflexes.
Common Causes We See in Wheat Ridge, CO
Understanding why spinal radiculopathy develops is key to preventing flare-ups and restoring long-term spinal health. Here are the causes I see most often in my Wheat Ridge patients:
Herniated or Bulging Discs
A disc that protrudes or herniates can press directly on a nerve root, triggering the classic shooting leg pain, numbness, or tingling associated with sciatica. This is the most common cause in patients under 50 and is often linked to lifting injuries or sudden movements that strain the spine.
Spinal Stenosis
Spinal stenosis occurs when the spinal canal narrows, either from congenital factors or age-related changes. This narrowing can squeeze nerve roots, causing pain, weakness, or difficulty walking. Symptoms often improve when sitting or leaning forward, but worsen with prolonged standing or walking.
Scoliosis
An uneven curve in the spine can compress nerves on one side, producing localized or radiating pain. Over time, compensatory muscle tension can further irritate nerve roots, increasing discomfort.
Trauma or Injury
Falls, car accidents, or sports injuries can create scar tissue, misalignments, or joint restrictions in the spine that irritate nerves. Even minor trauma can trigger a cycle of nerve compression and muscle compensation, leading to chronic radiculopathy.
Less Common Causes
Rare causes include tumors, intraspinal cysts, infections like osteomyelitis, and inflammatory or metabolic conditions (e.g., diabetes, ankylosing spondylitis, Paget’s disease, sarcoidosis). While uncommon, these are important to rule out during a thorough evaluation.
How We Treat Spinal Radiculopathy at The Disc Chiropractic
At The Disc Chiropractic, we take a multimodal, evidence-based approach to spinal radiculopathy. Our goal is to simply relieve nerve pressure, restore proper spinal mechanics, and get you back to your life.
Chiropractic Adjustments
Gentle, precise adjustments to the lumbar and thoracic spine help restore proper joint motion and alignment. By improving spinal mechanics, we reduce pressure on the affected nerve roots, which decreases pain and improves function.
Spinal Decompression Therapy
For patients with bulging or herniated discs pressing on nerve roots, we use spinal decompression therapy with the Triton DTS system. This gentle, controlled traction reduces pressure on the affected discs and nerve roots, promotes nutrient flow, and creates an environment for healing.
Shockwave Therapy
Chronic soft tissue tightness around the spine and nerve roots can prolong symptoms. Using high-energy acoustic waves, shockwave therapy targets trigger points, adhesions, and stiff muscles around the lumbar spine. This therapy stimulates tissue repair, increases circulation, and reduces inflammation, helping your adjustments and decompression sessions hold longer and work more effectively.
FAQs About Spinal Radiculopathy
What is spinal radiculopathy and how does it cause pain?
Spinal radiculopathy occurs when a spinal nerve is compressed or irritated, leading to pain that travels along the nerve’s path. The pressure on the nerve causes abnormal signaling, which the brain interprets as sharp, burning, or “electric” pain, often radiating from the lower back into the leg or from the neck into the arm.
How common is lumbar radiculopathy?
Lumbar radiculopathy affects an estimated 3%–5% of the general population, making it a common condition seen by spine specialists. Symptoms typically begin in midlife—men often notice them in their 40s, and women in their 50s and 60s.
What symptoms should make me suspect radiculopathy?
Typical symptoms include pain that radiates below the knee, numbness or tingling along a specific dermatome (nerve distribution), muscle weakness in the affected limb, and reduced reflexes. Many patients describe the pain as “electric” or “burning.”
What’s the difference between radiculopathy and sciatica?
“Radiculopathy” refers to nerve root compression anywhere along the spine, while sciatica specifically involves irritation of the sciatic nerve from the lower back into the leg. Sciatica is a common subtype of lumbar radiculopathy.
What causes spinal radiculopathy?
The most common causes include herniated or bulging discs, degenerative spine changes (arthritis, disc height loss), spinal stenosis (narrowing of nerve passageways), scoliosis, and less frequently tumors or infections. Herniated discs alone account for about 90% of radiculopathy cases in younger adults.
Can poor posture or repetitive strain cause radiculopathy?
Yes. Poor lifting mechanics, prolonged sitting with forward head posture, and repetitive strain from bending or twisting can stress spinal structures, contribute to degenerative changes, and increase pressure on nerve roots.
Who is at higher risk for developing spinal radiculopathy?
Risk factors include age (45–64 years), repetitive physical work or lifting, smoking, whole‑body vibration (e.g., long‑distance driving), mental stress that increases muscle tension, and a history of spinal degeneration or injury.
Can spinal radiculopathy go away on its own?
Many cases improve with conservative care—especially when treated early. Studies show a large proportion of patients with lumbar radiculopathy respond well to non‑surgical treatments like chiropractic care.
How is spinal radiculopathy diagnosed?
Diagnosis combines your history, symptom pattern, and physical examination. Tests like strength, sensation, and reflex checks help identify which nerve is involved. Imaging (MRI or CT) may be used when symptoms are severe, persistent, or worsening.
Why does radiculopathy cause weakness or numbness?
Nerve compression disrupts normal electrical signals from the spinal cord to muscles and skin. This can lead to muscle weakness in specific movements (e.g., foot dorsiflexion) and sensory changes (numbness or tingling) in precise nerve regions.
How long does it take to recover from radiculopathy?
Recovery depends on severity and underlying cause. Many patients notice improvement within 4–8 weeks with consistent conservative care. More chronic or severe nerve compression may take 3–6 months for lasting results.
Can chiropractic care help with spinal radiculopathy?
Yes. Research supports spinal adjustments for relieving nerve pressure and improving function. At The Disc Chiropractic, precise chiropractic care restores proper motion, reduces irritation of the nerve root, and improves spinal mechanics.
When is spinal decompression therapy appropriate?
Spinal decompression is especially useful when disc bulges or herniations contribute to nerve root compression. By gently relieving disc pressure, it promotes nutrient flow, reduces inflammation, and creates space around irritated nerves.
How does shockwave therapy help radiculopathy symptoms?
Shockwave therapy uses acoustic waves to stimulate blood flow and soft tissue healing around the spine. It’s particularly helpful for chronic muscle tightness and persistent trigger points that pull on spinal structures and worsen nerve irritation.
Should I avoid activity if I have radiculopathy?
Not necessarily. While heavy lifting and exacerbating positions should be moderated, gentle movement and guided therapeutic exercises help improve mobility, strengthen supporting muscles, and prevent stiffness that can worsen nerve compression.
Do I need surgery for spinal radiculopathy?
Most people with radiculopathy improve with conservative care. Surgery is typically considered only when symptoms are severe, progressive, or associated with significant weakness or loss of function. Studies show many non‑surgical cases stabilize or improve without invasive intervention.
Can radiculopathy cause permanent nerve damage?
If nerve compression is prolonged and severe, there is a risk of lasting changes. Early, targeted care—like adjustments, decompression, and soft tissue work—helps reduce pressure on the nerve early to protect function.
How do I know which nerve root is affected?
Symptom location often reflects the specific nerve root involved. For example, pain down the outside of the leg and into the foot suggests L5 involvement, while pain along the back of the leg and heel points to S1. A clinical exam combined with imaging helps confirm the diagnosis.
What lifestyle changes help manage or prevent radiculopathy?
Ergonomic improvements, weight management, regular core and spinal stabilization exercises, smoking cessation, and stress reduction all support spinal health and reduce the risk of recurrent nerve compression.
