Lumbar radiculopathy, commonly called a pinched nerve in the lower back, happens when a nerve root in the lower spine gets squeezed or irritated, causing pain that travels from your back down into your leg. It’s one of the most common reasons people see a spine specialist, and the good news is that most cases get better without surgery.

What Is Lumbar Radiculopathy? Lower Back Pinched Nerves and Sciatica

Your lower back, the lumbar spine, is made up of five vertebrae (the bones that stack to form your spine). Between each pair of vertebrae sits a cushioning disc, and nerve roots branch off the spinal cord and exit through small openings on either side. When one of those openings gets narrowed, the nerve root inside gets pinched.

You may hear lumbar radiculopathy called sciatica, especially when the pain runs down the back of the leg. Technically, sciatica refers to irritation of the sciatic nerve specifically, but the experience is similar: nerve pain that doesn’t stay in one place.

According to research, between 13% and 40% of people will experience lumbar radicular pain at some point in their lives.

Lumbar Radiculopathy Symptoms and Radiating Leg Pain

The most telling sign of lumbar radiculopathy symptoms is pain that moves. Instead of staying in your lower back, it shoots down into your buttock, thigh, calf or foot. Depending on which nerve root is affected, you might also notice:

• Burning, sharp or electric pain running down one leg
• Numbness or tingling along the leg or into the foot
• Muscle weakness, such as difficulty lifting your foot or pushing off your toes
• A deep ache in the buttock or hip that feels separate from back pain
• Symptoms that worsen when you sit for long periods, bend forward or cough

Some people never develop significant back pain at all. The leg symptoms arrive first, which can make it harder to connect the problem to the spine without a proper evaluation.

One important warning: if you experience sudden loss of bowel or bladder control, numbness in the groin or inner thighs, or weakness in both legs at once, go to the emergency room. These can be signs of cauda equina syndrome, a condition that requires immediate treatment.

Degenerative Causes of Lumbar Radiculopathy

Most cases of lumbar radiculopathy result from wear and tear on the spine over time. The discs between your vertebrae gradually lose water content and become less resilient.

When a disc wall cracks or bulges outward, called a herniated disc, it can press directly against a nearby nerve root. This is the most common cause, and it’s why symptoms can come on suddenly after something as ordinary as bending to pick something up.

Other structural changes in the lumbar spine can have the same effect:

• Bone spurs: Arthritic joints at the back of the spine can grow extra bone that crowds the nerve openings
• Thickened ligaments: The tissue lining the spinal canal can stiffen and bulge inward with age, especially at multiple levels
• Spondylolisthesis: When one vertebra slips forward over the one below it, the shift can stretch or compress the nerve roots nearby

Research found that higher BMI, smoking and jobs that involve repeated forward bending all increase the risk. Age is the single strongest factor. People over 30 face more than three times the risk compared to those under 20.

Advanced Lumbar Radiculopathy Treatment and Management

At University Orthopaedic Associates (UOA), we start by identifying exactly which nerve is involved and what’s causing the compression. Our Interventional Physiatry and Pain Management team uses physical examination, MRI and nerve testing (EMG and nerve conduction studies) to build a clear picture before recommending any treatment.

For most patients, non-surgical care resolves lumbar radiculopathy effectively. Options include:

• Physical therapy: Targeted exercises to strengthen the muscles supporting your spine and reduce pressure on the nerve
• Anti-inflammatory medication: To calm the swelling around the irritated nerve root
• Epidural steroid injections: Corticosteroid medication delivered directly to the nerve root
• Nerve root blocks: An injection that both pinpoints the affected nerve level and provides direct pain relief

When those approaches haven’t provided enough relief after six to twelve weeks, or if weakness is getting worse, our spine team offers minimally invasive procedures such as microdiscectomy and endoscopic discectomy. These remove the disc material pressing on the nerve through very small incisions, with faster recovery than traditional open surgery.

If leg pain, numbness or weakness has been slowing you down, don’t wait it out. University Orthopaedic Associates serves patients across New Jersey from offices in Somerset, Princeton, Wall, Woodbridge, Morganville and Monroe. Our team will evaluate your lumbar radiculopathy and build a plan to get you back to normal without relying on opioids. Call (732) 537-0909 or request an appointment online.
