What is Sciatica?

Commonly known as "sciatica," this condition is not a disease in itself, but rather a nerve compression syndrome that develops when the sciatic nerve is subjected to pressure or irritation.

The sciatic nerve, the longest and thickest nerve in the body, is formed by the union of nerve roots emerging from the lumbar spine and extends through the buttocks, thigh, leg, and down to the foot. Pressure on the nerve can cause not only pain but also numbness, tingling, a burning sensation, and muscle weakness. While mild cases may not significantly impact daily life, severe symptoms that make walking difficult can develop in advanced nerve compressions.

What is Sciatic Nerve Compression?

The most prominent symptom of sciatic nerve compression is pain that originates in the lower back and radiates to the buttock and down one leg. While some individuals experience this pain as a mild ache, others describe it as a sharp, electric shock-like pain, a burning sensation, or a stabbing pain. Depending on the degree of pressure on the nerve, numbness, tingling, and reduced muscle strength in the leg may also occur.

What Causes Sciatic Nerve Compression?

Sciatic nerve compression can have many different causes. For treatment to be successful, the underlying cause must first be identified.

Lumbar Herniated Disc

A herniated disc in the lower back is the most common cause of sciatic nerve compression. When the disc between the vertebrae bulges out and presses on the nerve roots, pain radiates from the lower back down the leg.

• Sudden onset lower back pain
• Pain that worsens when bending
• Electric shock-like sensation radiating down the leg
• Pain that increases with coughing and sneezing
• Loss of strength in the foot
• Inability to sit for long periods

Spinal Stenosis

In older age, narrowing of the spinal canal can lead to nerve compression. Leg pain that worsens particularly during walking and improves with rest are typical findings.

Piriformis Syndrome

Spasm of the piriformis muscle, located in the buttock region, can put pressure on the sciatic nerve. It is more common in individuals who sit for long periods. Symptoms may include deep pain in the buttock, complaints that worsen when sitting, and pain radiating down the back of the leg.

Trauma and Injuries

Falls, heavy lifting, sports injuries, or sudden movements can cause damage to the spine and surrounding tissues, leading to sciatic nerve compression.

Pregnancy

During pregnancy, the sciatic nerve can be affected due to increased weight, changes in body balance, and pressure from the growing uterus. Back and leg pain are common, especially in the later months of pregnancy.

Postural Disorders and Inactivity

Poor sitting habits, prolonged desk work, a sedentary lifestyle, and weak core and hip muscles can gradually put strain on the spine, creating pressure on the sciatic nerve.

What Are the Symptoms of Sciatic Nerve Compression?

Symptoms can vary from person to person. The most common symptoms include:

• Pain radiating from the lower back to the hip and leg
• Unilateral hip pain
• Numbness in the leg
• Tingling sensation
• Burning or electric shock-like pain
• Muscle weakness
• Inability to stand for long periods
• Difficulty walking
• Pain that worsens with movement
• Pain that intensifies after sitting for a long time
• A pulling sensation in the leg

In some patients, the pain remains localized in the lower back, while in others, it can radiate down to the foot.

How Is Sciatic Nerve Compression Diagnosed?

In diagnosis, the patient's symptoms and physical examination are very important. The areas to which the pain radiates, when it intensifies, and any accompanying neurological findings are evaluated.

If necessary, the following methods may be used:

• Physical examination
• Reflex assessment
• Muscle strength test
• Magnetic Resonance Imaging (MRI)
• Computed Tomography (CT)
• EMG (Electromyography)
• X-ray

How is Sciatic Nerve Compression Treated?

The treatment plan is determined based on the cause of the nerve compression and the severity of the symptoms.

Medication

Painkillers, anti-inflammatory drugs, and muscle relaxants used under a doctor's supervision can help control pain in the acute phase. However, unsupervised medication use is not recommended.

Physical Therapy

Physical therapy is one of the most important treatment methods for sciatic nerve compression. The goal is to reduce pressure on the nerve, strengthen muscles, and increase mobility.

A physical therapy program may include the following treatments:

• Stretching exercises
• Manual therapy
• Electrical stimulation
• Posture training
• Muscle strengthening exercises

Exercise

Regular exercises performed under expert supervision can help reduce symptoms in many patients.

Commonly recommended exercises include:

• Knee-to-chest stretch
• Piriformis stretch exercise
• Hamstring stretches
• Pelvic tilt exercise
• Cat-cow stretch
• Lower back stretches
• Core strengthening exercises

It should be remembered that incorrectly performed exercises can increase pain.

What Helps Sciatic Nerve Compression at Home?

In mild cases, certain lifestyle changes can help alleviate symptoms.

Methods that can be applied at home:

• Taking short walks
• Performing gentle stretches
• Avoiding sitting in the same position for long periods
• Avoiding lifting heavy loads
• Avoiding sudden movements
• Adopting correct sitting and posture habits
• Using appropriate beds and chairs that support the back
• Exercising regularly

These methods can only be supportive for mild complaints. Severe pain always requires evaluation by a specialist.

When Should You See a Doctor?

Some symptoms may indicate severe nerve compression and require urgent evaluation.

In the following situations, you should seek medical attention without delay:

• Progressive loss of strength in the leg
• Loss of bladder or bowel control
• Severe numbness
• Unbearable pain
• Difficulty walking
• Development of foot drop
• Back and leg pain beginning after trauma

Can Sciatic Nerve Compression Be Prevented?

While it may not be possible to prevent every case of sciatica, lifestyle habits that protect spinal health can reduce the risk.

To protect yourself, consider the following recommendations:

• Exercising regularly
• Maintaining a healthy weight
• Lifting heavy loads with proper technique
• Avoid prolonged sitting
• Establish an ergonomic workspace at your desk
• Strengthen back and abdominal muscles
• Adopt good posture habits
