Sciatica

Understanding Sciatica

Also known as: Sciatic Nerve Pain, Lumbar Radiculopathy (when nerve root-based), Sciatic Neuralgia "Sciatica" is one of those words that patients use as a diagnosis, but clinicians use as a symptom. It's pain traveling along the sciatic nerve — the longest nerve in the body, running from the lower back through the buttock and down the leg — and it's caused by something irritating that nerve upstream, most commonly a lumbar disc herniation, foraminal stenosis (narrowing of the nerve's exit tunnel), or muscular compression in the buttock (piriformis syndrome). Up to 40% of adults experience sciatica at some point in their life, and the majority improve with conservative chiropractic care. The classic description is a sharp, burning, or electric pain starting in the lower back or buttock and shooting down the back or side of the leg, sometimes reaching the calf or foot.

Numbness and pins-and-needles follow specific dermatomal patterns depending on which nerve root is involved — L4, L5, or S1. Sitting, coughing, sneezing, and bending forward typically worsen symptoms; walking or lying down may ease them. A positive straight leg raise test — where lifting the straight leg while lying flat reproduces the leg pain — is a classic clinical finding. The most common source is a lumbar disc bulge or herniation pinching the nerve root.

Spinal stenosis, spondylolisthesis, and piriformis muscle tightness are other frequent culprits. Prolonged sitting, heavy lifting with poor form, pregnancy, obesity, and weak core muscles all increase risk. Our protocol is comprehensive. Flexion-distraction (Cox Technique) gently decompresses the disc and opens the foraminal space.

Motorized spinal decompression provides deeper sustained traction for stubborn cases. Neural mobilization — "nerve flossing" — helps the irritated nerve slide more freely through its pathway rather than being stuck and reactive. Piriformis release with ART and trigger point therapy treats the muscular compression component when it's present. Class IV laser and PEMF calm nerve-root inflammation.

Core stabilization and McKenzie directional exercises rebuild the foundation. Most sciatica cases improve meaningfully within four to eight weeks. We refer for imaging and possible injection or surgical consultation for progressive weakness or failed conservative care — but that's a minority of patients. We may recommend: flexion-distraction/Cox, spinal decompression, ART, McKenzie directional exercises, Class IV laser, trigger point therapy, corrective exercise Seek immediate care if: You develop loss of bowel or bladder control, saddle-area numbness, bilateral leg weakness, or rapidly progressive foot drop — these may indicate cauda equina syndrome, a surgical emergency.
