Sciatica in St. Louis: Why "Just Stretch It" Isn't a Plan

If you've got pain shooting from your low back down the back of your leg, you've probably already Googled "sciatica." Good. But here's the problem: sciatica isn't a diagnosis. It's a symptom.

It tells us a nerve is irritated. It doesn't tell us why. And the "why" decides what actually fixes it.

What sciatica actually is

Your sciatic nerve is the biggest nerve in your body. It's built from nerve roots that leave your lower spine, run through your buttock and travel down the back of each leg to your foot.

When something squeezes or irritates those roots, you feel it along the nerve's path:

• Sharp, burning or electric pain from the buttock down the leg
• Numbness or tingling in the leg or foot
• Pain that's worse when you sit, cough, sneeze or bend forward
• Usually one side, not both

The usual suspects

Here's what I most often find behind sciatica in my St. Louis patients:

• Disc herniation or bulge. The disc between two vertebrae pushes out and presses on a nerve root. Common in people 30–50, and often worse sitting.
• Stenosis. Narrowing of the space the nerves travel through — more common after 50. Often worse standing and walking, better sitting or leaning forward.
• Joint dysfunction. Stiff or irritated joints in the low back or pelvis can refer pain down the leg that feels like sciatica.
• Piriformis and soft-tissue tension. A tight muscle deep in the buttock can irritate the nerve where it passes by.

Four different problems. Four different plans. That's why "stretch it out and take some ibuprofen" works for some people and does nothing for others.

Red flags: skip the chiropractor, go to the ER

Get emergency care right away if you have:

• Loss of bladder or bowel control, or trouble starting urination
• Numbness in the groin, inner thighs or "saddle" area
• Weakness that's getting worse — tripping, foot slapping the floor, a leg that gives out
• Symptoms in both legs at once
• Back pain with fever, unexplained weight loss or a history of cancer
• Pain that started after a major fall or crash

These can signal nerve compression that needs urgent medical attention. Don't wait them out.

How we figure out what's driving yours

We don't guess, we test. A sciatica evaluation at Gateway includes:

• A detailed history — when it started, what makes it worse, what makes it better
• Orthopedic tests to separate disc, joint and muscle sources
• Neurological testing — reflexes, strength and sensation, so we know which nerve root is involved and how irritated it is
• Motion Study X-Rays when they're warranted, to see how your spine actually moves — not just how it looks standing still

If your exam points to something that needs an MRI, a specialist or a medical referral, we'll tell you straight.

What treatment looks like

Once we know the cause, the plan matches it:

• Disc-driven sciatica often responds to spinal decompression, which gently takes pressure off the disc and nerve, plus targeted adjustments and specific exercises.
• Joint-driven pain responds to precise adjustments to restore motion in the low back and pelvis.
• Soft-tissue involvement gets addressed with muscle work, therapy and mobility drills.

Most people also get a short list of things to do (and stop doing) at home — how to sit, sleep and move so you're not re-aggravating it all day.

We measure progress as we go. If you're not improving the way we expect, we change course or refer you out. No endless care plans.

The bottom line

Sciatica is a signal, not a sentence. The fastest way out is finding the actual source — and then treating that.
