Lumbar Radiculopathy and Sciatica in San Antonio, TX

Lumbar radiculopathy refers to a condition in which one or more of the nerve roots in the lower back are compressed or irritated, often resulting in pain, weakness, numbness, or tingling that radiates from the lower spine into the leg. This nerve compression disrupts normal nerve function and can significantly affect mobility and daily activities. The term “radiculopathy” describes nerve root dysfunction, and when it occurs in the lumbar region, it typically involves the sciatic nerve, leading to a condition commonly referred to as sciatica.

In fact, sciatica is one of the most common forms of lumbar radiculopathy. It occurs when the sciatic nerve—the largest nerve in the body—is affected by this nerve root compression. The resulting pain often travels from the lower back through the buttock and down the leg, following the path of the sciatic nerve.

Lumbar radiculopathy is most often caused by structural issues in the spine that press on nerve roots. This can develop gradually over time due to age-related changes or suddenly from trauma. Contributing factors include:

• Herniated or slipped discs

• Degenerative disc disease

• Spinal stenosis (narrowing of the spinal canal)

• Bone spurs (osteophytes)

• Traumatic injury or repetitive motion stress

These structural issues can lead to inflammation, compression, or irritation of the nerve roots, resulting in pain and neurological symptoms that may affect daily movement and quality of life. In some cases, poor posture, obesity, or prolonged sitting can contribute to or worsen existing spinal problems. Addressing the root cause early through lifestyle adjustments and medical guidance can help prevent symptoms from progressing and reduce the need for invasive treatment.

Symptoms of lumbar radiculopathy vary depending on the specific nerve root involved, but they typically follow a pattern based on the nerve’s pathway. When the sciatic nerve is affected, symptoms extend down the leg, known as sciatica. Common signs include:

• Radiating pain from the lower back to the buttocks and down the leg

• Numbness or tingling in the leg or foot

• Muscle weakness in the affected limb

• Burning or sharp shooting pain, often worsened by sitting or movement

Diagnosis begins with a thorough medical history and physical exam, focusing on symptoms and neurological function. To confirm the diagnosis and pinpoint the source of nerve irritation, healthcare providers may use imaging and nerve tests:

• MRI or CT scan to visualize discs, nerves, and soft tissue

• X-rays to check for bone alignment or degeneration

• Electromyography (EMG) and nerve conduction studies to assess nerve damage and muscle response

Treatment typically starts with conservative, non-surgical approaches aimed at relieving pressure on the nerve and reducing inflammation. The goal is to manage pain and restore function. Treatment options include:

• Physical therapy and core-strengthening exercises

• Heat or cold application

• Activity modification to avoid aggravating movements

• Epidural steroid injections for inflammation relief

• Surgery (e.g., discectomy or laminectomy) may be considered if symptoms persist or worsen despite conservative care
