Few things get a patient into our office faster than sciatica. The pain is hard to ignore — a sharp, burning, or electric sensation that shoots from the lower back through the buttock and down one leg, sometimes all the way to the foot. It can make sitting unbearable, disrupt sleep, and turn simple tasks like putting on shoes into an ordeal.

What makes sciatica particularly frustrating is that many patients are told to rest, take anti-inflammatories, and wait it out. For some, that works. For many others, the pain returns — or never fully goes away — because the underlying cause was never addressed.

What Sciatica Actually Is

Sciatica is not a diagnosis in itself. It is a symptom — specifically, pain that follows the path of the sciatic nerve, which is the longest and widest nerve in the human body. The sciatic nerve originates from nerve roots at the L4, L5, and S1 levels of the lumbar spine, passes through the buttock, and travels down the back of the leg to the foot.

When any of those nerve roots are compressed, irritated, or inflamed, the result is the characteristic radiating pain, numbness, tingling, or weakness that patients describe as sciatica.

The Most Common Causes

Disc herniation: The most frequent cause of true sciatica. When the soft inner material of a lumbar disc pushes through its outer wall, it can press directly on a nerve root. Even a small herniation can produce significant pain if it contacts the nerve.

Spinal stenosis: A narrowing of the spinal canal or the openings through which nerve roots exit the spine. More common in patients over 50, stenosis can compress the sciatic nerve roots and cause pain that worsens with standing and walking.

Piriformis syndrome: The piriformis muscle in the buttock sits directly over the sciatic nerve. When this muscle becomes tight or spasms — from prolonged sitting, overuse, or trauma — it can compress the nerve and produce sciatic-like symptoms. This is sometimes called "pseudo-sciatica."

Degenerative disc disease: As discs lose height and hydration over time, the space available for nerve roots decreases. This can lead to chronic nerve irritation and intermittent sciatic symptoms.

Sacroiliac joint dysfunction: The SI joint connects the sacrum to the pelvis. When it becomes inflamed or moves abnormally, it can irritate the nerve roots nearby and produce pain that mimics sciatica.

Why Rest and Medication Are Often Not Enough

Anti-inflammatory medications can reduce the inflammation around an irritated nerve root and provide temporary relief. Rest can prevent further aggravation. But neither addresses the mechanical problem — the disc herniation, the joint restriction, the muscle tightness — that is compressing the nerve in the first place.

Without addressing the cause, sciatica has a high recurrence rate. Many patients cycle through flare-ups for years, each one potentially more severe than the last.

How Chiropractic Care Addresses Sciatica

Chiropractic care is one of the most effective conservative treatments for sciatica, with multiple clinical trials supporting its use for lumbar disc herniation and nerve root compression.

At Evergreen Spinal Health Center, treatment for sciatica begins with a thorough evaluation to identify the specific cause and level of nerve involvement. Treatment typically includes:

Spinal adjustments: Targeted adjustments to the lumbar spine and pelvis reduce joint restriction, improve spinal mechanics, and decrease the mechanical pressure on the affected nerve root. Many patients experience significant relief within the first few treatments.

Flexion-distraction technique: A gentle, non-force technique that creates negative pressure within the disc, helping to draw herniated material back toward the center and reduce nerve compression.

Soft tissue therapy: Releasing the piriformis and other hip muscles reduces muscular compression on the sciatic nerve and improves the overall mechanics of the lower back and pelvis.

Therapeutic exercises: Core stabilization exercises and specific stretches reduce the load on the lumbar discs and help prevent recurrence.

When to Seek Care Immediately

Most sciatica can be managed conservatively with chiropractic care. However, certain symptoms require immediate medical attention:

• Loss of bladder or bowel control
• Numbness in the groin or inner thighs (saddle anesthesia)
• Progressive weakness in both legs
• Sciatica following a significant trauma

These symptoms may indicate cauda equina syndrome, a rare but serious condition that requires emergency care.

If your sciatica is interfering with your daily life, do not wait for it to resolve on its own. Call Evergreen Spinal Health Center at (253) 683-4277 to schedule an evaluation with Dr. Tim Joy.

Frequently Asked Questions About Sciatica

How long does sciatica last without treatment?

Mild sciatica from a small disc herniation sometimes resolves on its own within 4 to 6 weeks. However, moderate to severe sciatica — especially when caused by significant disc herniation or stenosis — rarely resolves without treatment and has a high recurrence rate. Early intervention with chiropractic care typically leads to faster recovery and lower recurrence rates than watchful waiting.

Can chiropractic adjustments make sciatica worse?

In the hands of a qualified chiropractor, adjustments for sciatica are safe and effective. Dr. Joy performs a thorough evaluation — including orthopedic and neurological testing — before any treatment to confirm that chiropractic care is appropriate and to identify the safest approach for your specific situation. Some patients experience mild soreness after their first few adjustments, which typically resolves within 24 hours.

Is sciatica the same as a pinched nerve?

Sciatica is a specific type of pinched nerve — one that involves the sciatic nerve or the lumbar nerve roots that form it. "Pinched nerve" is a general term that can refer to nerve compression anywhere in the spine. The treatment principles are similar: identify and address the mechanical cause of the compression to relieve pressure on the nerve.
