Understanding Lumbar Radiculopathy and Sciatica

Pain that begins in the lower back and travels into the buttock, thigh, calf, or foot may involve irritation of a nerve in the lumbar spine.

This condition is commonly referred to as lumbar radiculopathy. The term sciatica is also frequently used to describe pain that travels along the sciatic nerve distribution into the leg.

What Causes Lumbar Radiculopathy?

Nerves exit the spinal canal through openings between the vertebrae. When one of these nerves becomes compressed or inflamed, pain and other neurological symptoms can develop.

Common causes include a herniated disc, degenerative disc changes, spinal stenosis, arthritis, bone spurs, or narrowing around the spinal nerves.

The location of the affected nerve often determines where symptoms are felt.

What Does It Feel Like?

Lumbar radiculopathy can present differently in every patient.

Some patients experience sharp or shooting pain down the leg. Others describe burning, tingling, numbness, or weakness.

Significant leg symptoms can sometimes occur even when lower back pain itself is relatively mild.

Certain movements, prolonged sitting, standing, bending, coughing, or walking may aggravate symptoms depending on the underlying cause.

How Is It Diagnosed?

Evaluation begins with a detailed history and physical examination. Strength, sensation, reflexes, mobility, and the distribution of symptoms may help identify which nerve is involved.

MRI imaging can provide additional information about the discs, spinal canal, and areas surrounding the nerves.

In some cases, an EMG and nerve conduction study may be recommended to further evaluate nerve function.

What Are the Treatment Options?

Treatment depends on the severity of symptoms, the underlying cause, and whether neurological changes such as weakness are present.

Conservative treatment may include physical therapy, activity modification, and medications.

For persistent symptoms, an epidural steroid injection may be considered to reduce inflammation around an irritated spinal nerve.

More advanced treatment or surgical evaluation may be appropriate when significant nerve compression, progressive weakness, or other concerning findings are present.

At Ospina Medical, treatment decisions are based on how the patient feels, what the examination shows, and how imaging findings relate to the patient's actual symptoms.
