What sciatica actually is
Sciatica isn't a diagnosis, it's a symptom. The term describes pain, tingling, or numbness traveling down the back of the leg, caused by irritation of the sciatic nerve or its contributing nerve roots. The sciatic nerve is the largest nerve in the body, formed from nerve roots that exit the lower spine. When any point along that pathway gets compressed or inflamed, the whole nerve transmits pain.
What's actually causing it
The most common sources are: a herniated or bulging lumbar disc pressing on a nerve root, narrowing of the spinal canal (stenosis), arthritic changes in the spine, piriformis syndrome (where a deep glute muscle compresses the nerve), or sacroiliac joint dysfunction.
Effective treatment depends entirely on identifying which of these is the driver. A treatment plan that targets a herniated disc when the actual problem is piriformis tightness will fail, and that's why so many people bounce between providers without lasting relief.
The roadmap that works
Our typical approach has four phases:
- Calm the inflammation. Early sessions focus on reducing the acute irritation around the nerve with targeted soft tissue work, gentle traction, and electrical modalities.
- Restore mobility. Once the area calms, chiropractic adjustments restore movement to stuck joints in the lumbar spine and pelvis, taking pressure off the nerve.
- Rebuild stability. Targeted core and glute strengthening prevents the same compression from coming back. Without this phase, sciatica usually returns within a year.
- Address the trigger. Whether that's posture at work, lifting mechanics, or running form, fixing the daily pattern that caused the problem is what makes recovery durable.
When surgery actually is the right call
A small minority of sciatica cases warrant surgical evaluation, specifically, those with progressive neurological deficits, severe weakness, or loss of bowel or bladder control. These are red flags. Outside of those situations, well over 90% of patients recover fully with conservative care, often faster than with surgery and without the risks.
Realistic timeline
Most patients feel substantial relief within 4-8 weeks of consistent care. Complete recovery, including the stability work, typically takes 3-6 months. The patients who do best stick with the strengthening phase even after the pain is gone, because that's what keeps it gone.
