What Is Sciatica?
Sciatica is pain that radiates along the path of the sciatic nerve — the longest and thickest nerve in the body. It runs from the lower back through the hips and buttocks and down each leg. When something compresses or irritates this nerve, it produces pain, numbness, or tingling that can travel from your lower back all the way to your foot.
Sciatica is not a diagnosis itself — it's a symptom of an underlying problem, most commonly a herniated disc, bone spur, or spinal stenosis in the lumbar spine. Identifying the root cause is essential for effective treatment.
At DFW Accident & Injury Centers, we see sciatica patients in Arlington who've been suffering for weeks, months, or even years — often after being told their only option is surgery or long-term medication. Chiropractic care offers a proven, non-invasive alternative.
Sciatica Symptoms
Common Causes of Sciatica
Herniated or Bulging Disc
The most common cause. A damaged lumbar disc presses against the sciatic nerve root, producing radiating pain and neurological symptoms.
Spinal Stenosis
Narrowing of the spinal canal compresses the nerve roots that form the sciatic nerve, especially common in patients over 50.
Auto Accident Trauma
The impact forces of a collision can herniate discs, shift vertebrae, and inflame tissues surrounding the sciatic nerve.
Piriformis Syndrome
The piriformis muscle deep in the buttock can spasm and compress the sciatic nerve, mimicking disc-related sciatica.
Degenerative Disc Disease
Age-related disc degeneration reduces disc height and can cause bone spurs that impinge on nerve roots.
How We Treat Sciatica
Lumbar Adjustments
Targeted adjustments to the lower spine to reduce disc pressure on the sciatic nerve and restore proper vertebral alignment.
Flexion-Distraction Therapy
A gentle, pumping motion that increases disc space, moves the herniation away from the nerve, and improves circulation to the area.
Spinal Decompression
Controlled traction that creates negative pressure within the disc, encouraging retraction of herniated material.
Piriformis Release
Targeted soft tissue work to release the piriformis muscle when it's the source of sciatic nerve compression.
Core Stabilization
Progressive strengthening exercises to support the lumbar spine and prevent recurrence of nerve compression.
When to Seek Immediate Medical Attention
- ⚠ Sudden loss of bladder or bowel control (cauda equina syndrome — emergency)
- ⚠ Rapidly progressive weakness in one or both legs
- ⚠ Numbness in the groin or inner thighs
- ⚠ Sciatica following a severe trauma or high-speed accident
Frequently Asked Questions
Can a chiropractor fix sciatica?
Chiropractic care is one of the most effective non-surgical treatments for sciatica. Most patients experience significant relief within weeks.
How long does sciatica treatment take?
Mild cases may resolve in 4–6 weeks. More severe or chronic sciatica may require 8–12 weeks of consistent care.
Is sciatica caused by car accidents?
Yes. The impact forces can herniate discs or shift vertebrae, directly compressing the sciatic nerve.
Do I need surgery for sciatica?
Most sciatica resolves with conservative care. Surgery is typically only recommended when there's progressive neurological loss or failed conservative treatment.
What's the best sleeping position for sciatica?
Sleeping on your side with a pillow between your knees, or on your back with a pillow under your knees, typically reduces pressure on the sciatic nerve.
