Sciatica: When Back Pain Travels Down Your Leg
Sciatica is leg pain following the path of the sciatic nerve — often sharp, burning, or electric — usually caused by a disc or bony change irritating a nerve root in the lower spine. Most cases improve substantially within weeks to a few months with conservative care.
What sciatica is (and isn’t)
True sciatica follows a nerve’s territory — commonly below the knee, sometimes to the foot — and may bring tingling, numbness, or weakness. Aching that stays in the buttock or thigh is more often referred joint or muscle pain, which behaves differently. The distinction changes both the outlook and the plan, and an exam can usually make it without imaging.
The reassuring natural history
Most disc-related sciatica improves meaningfully within six to twelve weeks; the body gradually resorbs disc material and irritation settles. Staying gently active within tolerance beats bed rest consistently in trials. The urgent exceptions: loss of bowel or bladder control, saddle numbness, or progressive leg weakness — these need immediate care, not a wait-and-see plan.
How we approach a sciatic episode
A licensed provider confirms the pattern, tests strength and reflexes, screens the red flags, and sets a paced plan: activity within tolerance, progressive loading as symptoms centralize, and honest checkpoints. Imaging enters when the exam or trajectory demands it. Where candidacy screening supports it, a personalized restorative protocol may be discussed alongside the fundamentals — never as a substitute for them.

Sciatica & Leg Pain: quick answers
Should I get an MRI for sciatica?
Not usually at the start. Most episodes improve within weeks, and disc findings are common even in pain-free adults. Imaging earns its place when red flags appear, weakness progresses, or symptoms defy the expected trajectory.
Is walking good for sciatica?
For most people, yes — short, frequent walks within tolerance are among the best early medicines. Pain that worsens the further you walk and eases when you sit deserves specific evaluation, as it suggests a different pattern.

A provider-led evaluation identifies the actual source and tells you plainly which conservative, non-surgical options fit — and whether you’re a candidate at all.
