Sciatica: Causes, Symptoms & Non-Surgical Treatment

That sharp, electric pain shooting down your leg has a name: sciatica. It’s a symptom of an irritated or compressed sciatic nerve, and the good news is that most cases respond well to non-surgical care.

What sciatica feels like

  • Pain radiating from the lower back into the buttock and down a leg
  • Numbness, tingling, or a “pins and needles” sensation
  • Burning or electric-like pain, often worse when sitting
  • Weakness in the affected leg

MedlinePlus notes that sciatica usually affects only one side of the body.

What causes it

The sciatic nerve gets compressed or irritated, commonly by a herniated or bulging disc, spinal stenosis, or misalignment in the lower spine. Pinpointing the source is the key to relief. Mayo Clinic notes most sciatica improves without surgery.

Non-surgical treatment

  • Spinal decompression gently opens space in the spine to take pressure off the nerve.
  • Chiropractic adjustments realign the spine to reduce irritation and restore movement.

Both are drug-free and address the cause rather than masking it.

When to seek care

If the pain lingers, keeps returning, or comes with leg weakness, get evaluated. Early care helps prevent a flare-up from becoming a chronic problem. The American Academy of Orthopaedic Surgeons also flags progressive leg weakness as a sign that deserves prompt attention.
