Is It Sciatica? Understanding Leg Pain That Starts in Your Spine

Leg pain is confusing because it so rarely starts in the leg. When discomfort radiates from your lower back down through the buttock and into the leg — sometimes with tingling, burning or numbness — the sciatic nerve is usually involved.

What sciatica actually is

Sciatica is not a diagnosis so much as a description: it means something is irritating or compressing the sciatic nerve, most often where it exits the lower spine. Pinning down that “something” is the whole point of a proper evaluation. Our sciatica page walks through the common causes in plain language.

Why rest alone rarely fixes it

Resting can calm a flare, but if the underlying mechanical pressure on the nerve remains, the pain returns the moment you resume normal activity. Lasting relief comes from reducing that pressure — which is exactly what corrective care is designed to do.

When to get it checked

If leg symptoms last more than a few days, keep returning, or come with weakness, it is worth a professional assessment rather than waiting it out. The sooner the cause is identified, the simpler the path back tends to be. Visit us in Arlington Heights when you are ready for answers.
