Back pain and leg pain are among the most common reasons patients seek help from a neurosurgeon in Los Angeles. Two conditions frequently responsible for these symptoms are sciatica and spinal stenosis. Although they may feel similar at first, these conditions have different causes, different imaging findings, and different treatment approaches.
At my practice, Dr. Luke Macyszyn Neurosurgery, serving Marina Del Rey, Tarzana, and greater Los Angeles, I often see patients who have spent months—or even years—living with discomfort without a clear diagnosis. Understanding the difference between sciatica and spinal stenosis is important because an accurate diagnosis plays a critical role in recovery and long-term outcomes.
Sciatica refers to irritation or compression of the sciatic nerve, the largest nerve in the body. The sciatic nerve originates in the lower spine and travels through the hips and down each leg. Sciatica is not technically a diagnosis itself—it is a symptom caused by an underlying spine condition.
The most common causes include:
A herniated disc is particularly common in younger and middle-aged adults.
Patients with sciatica often experience:
Sciatica symptoms usually affect one side of the body and can range from mild discomfort to debilitating nerve pain.
Spinal stenosis occurs when the spaces within the spinal canal narrow, placing pressure on the spinal cord or nerves.
Lumbar spinal stenosis is especially common in adults over age 60 and is frequently related to age-related degeneration.
Common causes include:
Unlike sciatica, spinal stenosis is typically progressive and develops slowly over time.
Patients with spinal stenosis may notice:
One hallmark sign of lumbar stenosis is that symptoms improve when bending forward or sitting.
Although both conditions involve nerve compression, there are important differences.
Pain Pattern
Sciatica often causes sharp, shooting pain down one leg.
Spinal stenosis typically causes aching, heaviness, or cramping in both legs.
Age Group
Sciatica is more common in younger adults with disc herniations.
Spinal stenosis is more common in older adults with degenerative spine disease.
Activity Triggers
Sciatica pain often worsens with sitting.
Spinal stenosis pain usually worsens with standing or walking.
Walking Tolerance
Patients with spinal stenosis frequently report needing to stop walking after short distances because of leg weakness or pain.
A precise diagnosis begins with a detailed neurological examination and advanced imaging.
A diagnosis often includes:
MRI is especially important because it allows visualization of nerve compression, disc abnormalities, and spinal canal narrowing.
Patients are encouraged to bring prior imaging studies or submit MRI scans for review before their consultation.
Many cases of sciatica improve without surgery.
Initial treatment may include:
When symptoms persist or neurological weakness develops, minimally invasive spine surgery may be recommended.
Common procedures include:
Minimally invasive techniques help reduce muscle disruption, shorten recovery, and allow faster return to daily life.
Treatment for spinal stenosis depends on severity.
Mild spinal stenosis may improve with:
Severe spinal stenosis often requires decompression surgery to relieve pressure on spinal nerves.
Procedures may include:
As a fellowship-trained spine surgeon, I specialize in minimally invasive approaches designed to preserve mobility whenever possible.
You should seek evaluation if you experience:
Early diagnosis can help prevent permanent nerve damage.
Sciatica and spinal stenosis are often confused because both involve nerve-related symptoms. However, treating the wrong condition can delay recovery and prolong pain.
An experienced neurosurgeon near you can identify subtle differences in symptoms and imaging findings that guide the correct treatment plan.
