LUMBAR RADICULOPATHY
If you’re suffering from Lumbar Radiculopathy, please schedule an appointment with one of our orthopedic specialists as soon as possible.
What is Lumbar Radiculopathy?
Lumbar radiculopathy develops when a nerve root in the lower back becomes compressed or irritated. A herniated disc, spinal stenosis, or other spinal condition can place pressure on the nerve, causing pain, numbness, tingling, or weakness that travels from the lower back into the buttock, leg, or foot.
The lumbar spine contains nerves that control sensation and movement throughout the lower body. When pressure disrupts normal nerve function, patients often experience symptoms that radiate along the path of the affected nerve. As nerve irritation continues, symptoms may become more frequent, severe, or limiting during daily activities.
What Causes Lumbar Radiculopathy?
Lumbar radiculopathy develops when a structure in the lower spine compresses or irritates a nerve root, disrupting normal nerve signals and causing pain, numbness, tingling, or weakness that travels into the lower body. Common causes include:
- Herniated disc: Disc material bulges or ruptures and presses on a nearby nerve root.
- Spinal stenosis: Narrowing of the spinal canal reduces space for nerve roots and increases pressure on nerves.
- Degenerative disc disease: Age-related disc breakdown reduces cushioning and allows irritation of nearby nerve roots.
- Bone spurs: Extra bone growth narrows nerve pathways and compresses nearby nerves.
- Spinal injury: Trauma shifts spinal structures and places direct pressure on nerve roots.
Symptoms of Lumbar Radiculopathy
Lumbar radiculopathy produces symptoms when a compressed or irritated nerve root disrupts normal communication between the spine and lower body. Pain often starts in the lower back and travels into the buttock, thigh, leg, or foot along the path of the affected nerve. Movement, sitting, coughing, or standing for long periods can worsen symptoms. Many patients also notice reduced strength and difficulty with specific movements.
As nerve irritation continues, symptoms often progress and interfere with daily function. Patients develop numbness, tingling, or burning sensations in the leg or foot. Muscle weakness can make walking, lifting the foot, or maintaining balance more difficult. Severe weakness, loss of coordination, or changes in bladder or bowel control require urgent medical evaluation.
Treatment Options for Lumbar Radiculopathy
Orthopedic spine specialists and neurosurgeons treat lumbar radiculopathy by relieving nerve pressure, reducing pain, and restoring normal function. Clinicians usually start with conservative care.
Non-surgical treatments may include:
- Anti-inflammatory medications to reduce nerve irritation and pain
- Physical therapy to improve flexibility, strengthen core muscles, and support the spine
- Activity modification to avoid movements that worsen nerve compression
- Low-impact exercise such as walking or swimming to maintain mobility and circulation
- Stretching routines to reduce stiffness and improve spinal movement
- Hot or cold therapy to ease inflammation and muscle tension
If conservative care fails, clinicians may use corticosteroid injections to reduce inflammation around the affected nerve root. In more severe cases, surgeons may perform procedures such as a discectomy or laminectomy to remove pressure from the nerve and restore function.
When to Seek Professional Care for Lumbar Radiculopathy
Seek professional care for lumbar radiculopathy when lower back pain persists beyond a few weeks, worsens, or interferes with daily activities. Pain that limits walking, standing, or normal movement despite rest requires prompt evaluation. Immediate care is needed when severe leg weakness, loss of coordination, or changes in bladder or bowel control occur. These symptoms often signal significant nerve compression that requires urgent treatment.
