The pain that radiates from the lower back down one or both legs affects thousands of people in Costa Rica and is one of the most common reasons for neurosurgery consultations. This discomfort, known as sciatica, originates from compression or irritation of the sciatic nerve, the longest and thickest nerve in the human body. Its impact can significantly limit work, recreational, and daily activities.
Our neurosurgery team has treated numerous cases of this condition, allowing us to offer a comprehensive approach ranging from accurate diagnosis to minimally invasive procedures when necessary. Understanding the causes and treatment options is essential to regain quality of life.
What is Sciatica and What Are Its Main Causes?
Sciatica is not a disease itself, but rather a group of symptoms that arise when the sciatic nerve is compressed or irritated along its path. This nerve originates in the lumbar region of the spine and runs down the back of each leg to the foot, so any disturbance along its course can cause severe pain.
The most common causes include:
- Lumbar disc herniation, when material from the intervertebral disc moves and presses on the nerve root
- Spinal stenosis, the narrowing of the spinal canal that compresses the nerves
- Spondylolisthesis, the slipping of one vertebra over another
- Piriformis syndrome, when the piriformis muscle compresses the nerve in the gluteal region
- Traumatic injuries or degeneration related to aging
Factors such as excess weight, a sedentary lifestyle, improper lifting of heavy objects, and certain jobs that require prolonged sitting increase the risk of developing this condition.
Characteristic Symptoms to Recognize Sciatica
The distinguishing sign of sciatica is pain extending from the lumbar area down the leg, usually on one side. However, the intensity and characteristics can vary widely from person to person. Some patients describe a sharp or burning sensation, while others experience numbness or tingling.
Common Manifestations
Besides radiating pain, muscle weakness in the affected leg, difficulty moving the foot or toes, and discomfort that worsens when sitting, coughing, or sneezing are frequent. In severe cases, loss of bowel or bladder control may occur, which is a medical emergency requiring immediate attention.
Clinical evaluation includes a thorough physical exam and, when necessary, imaging studies such as MRI or CT scans to identify the specific cause of nerve compression. Accurate diagnosis is crucial to determine the most appropriate therapeutic approach.
Conservative Treatment Options and When to Consider Surgery
Most sciatica episodes respond well to conservative treatment. This initial approach includes physical therapy, anti-inflammatory and pain-relief medications, as well as modifications to daily activities to avoid movements that worsen symptoms. Prolonged absolute rest is no longer recommended, as controlled mobility supports recovery.
Epidural corticosteroid injections can provide temporary relief in cases of severe pain, enabling the patient to engage in rehabilitation. However, if symptoms persist for more than six to eight weeks without improvement, progressive muscle weakness appears, or pain severely interferes with daily functioning, surgery may become the most suitable option.
Recommendations for Pain Management and Prevention
Maintaining proper posture during daily activities is a key foundation for preventing recurrent episodes. Strengthening abdominal and lumbar muscles through specific exercises provides additional support to the spine and reduces the load on the intervertebral discs.
Other preventive measures include maintaining a healthy weight to decrease pressure on the spine, taking active breaks if the job requires long hours of sitting, using proper techniques when lifting objects, engaging in regular low-impact physical activity, and avoiding prolonged use of inappropriate footwear that disrupts walking mechanics.
