Pain, numbness or tingling that shoots from your lower back down your leg is called sciatica. Here's what causes it, what you can do today, and the non-surgical treatment options we offer in Palo Alto.
What the Research Says
When sciatica comes from a herniated disc, the instinct is often to assume surgery is inevitable. The research says otherwise. A 2024 systematic review and meta-analysis found that conservative treatment for sciatica reduced leg pain more than surgery and improved both physical and mental health scores. Surgery did better for back pain specifically, but the authors concluded that conservative care should be the starting point unless there's a neurological emergency.
Chiropractic care has a place in that approach. A review in American Family Physician summarized trials showing that chiropractic adjustments for sciatica caused by disc herniation increased patients' self-perceived improvement compared with a placebo treatment, and a separate trial found spinal manipulation helped more patients than traction did. The same review stresses careful case selection, which is why a thorough exam comes before any treatment.
Perhaps the most reassuring finding concerns the herniation itself. A review of research on herniated disc recovery without surgery highlighted that herniation size didn't predict how well people recovered with non-surgical care, and that even very large herniations have been managed conservatively. A frightening MRI report doesn't automatically mean an operation.
What Sciatica Actually Is
Sciatica is a symptom rather than a diagnosis. The sciatic nerve forms from nerve roots in the lower spine and runs through the buttock and down the back of the leg. When something irritates one of those roots, you feel it along the nerve's path: a deep ache in the buttock, burning or electric pain down the leg, numbness or tingling in the foot, sometimes weakness.
The most common cause is a disc. The soft center pushes outward through a weakened area of the outer ring, and both the pressure and the chemical inflammation it releases irritate the nearby nerve root. Usually the disc has been under strain for months or years from sitting, bending, and lifting before one ordinary movement sets off symptoms. Tight muscles around the hip, joint restrictions, and narrowing of the spaces where the nerves exit can also be involved, which is why pinning down the real source matters.
Who Gets Sciatica in Palo Alto
- The desk worker — Years of sitting put steady pressure on the lower discs. Then one morning, bending to pick up a dropped pen sends pain shooting down the leg.
- The long-distance commuter — An hour or more each way on 101 or 280, sitting still with vibration through the seat. The buttock aches first, and over time the pain starts traveling.
- The lifter — Whether it's deadlifts at the gym or hauling materials on a job site, repeatedly lifting with a rounded back loads the discs in exactly the way they handle worst.
- The active adult over 50 — Discs naturally lose water and height with age. A disc that tolerated decades of activity becomes more vulnerable, and a modest strain can trigger nerve symptoms.
Why Getting Evaluated Early Matters
Here's the honest picture: many sciatica episodes improve over time, and that's good news. But the weeks you spend waiting aren't neutral. People with leg pain tend to stop moving, sleep poorly, and lean on medication, and that combination slows recovery and leaves the back deconditioned for the next episode. Early, guided care keeps you moving safely while the irritation settles.
An early exam also screens for the uncommon situations that can't wait. Seek emergency care right away if you have new trouble controlling your bladder or bowels, numbness in the groin or inner thighs, or leg weakness that's getting worse. Those signs need immediate medical attention, not a wait-and-see approach.
What You Can Do Today
Keep walking. Short, easy walks on flat ground often feel better than sitting or lying down for long periods, and staying gently active supports recovery. Stop if the leg pain clearly worsens.
Break up sitting. If sitting aggravates your symptoms, get up every 20 to 30 minutes. When you do sit, keep your lower back supported rather than slumped.
Notice what changes it. Pay attention to which positions and movements make the leg pain better or worse. That information is genuinely useful in your evaluation.
Your First Visit: What to Expect
Your initial appointment is a comprehensive 3-step process designed to move you from pain to performance. It is a paid visit, separate from the free consultation.
Medical history review, orthopedic and neurological testing, and biomechanical analysis to understand not just where it hurts, but why it hurts.
We sit down with you to explain what is causing your pain, our recommended recovery plan, and how long we expect your recovery to take.
When it is possible and safe to do so, we begin your first phase of therapy during your first visit: gentle spinal adjustments, manual soft-tissue therapy, or initial corrective exercises.
