Sciatica Explained: It's Not a Diagnosis, and Nobody Tells You That

If someone has told you that you have sciatica, I'm guessing you left that appointment with more questions than answers. That's what I hear from patients all the time. Someone says the word "sciatica," hands over a sheet of stretches or a prescription, and you're sitting there thinking, okay, but what is actually wrong with me?

It bugs me, honestly, because the most helpful thing you could hear in that first visit is also the simplest: sciatica isn't a diagnosis. It's a symptom.

It tells you where you feel it, not why. That pain, tingling, or burning that runs from your low back or butt down the back of your leg, sometimes all the way to your foot? That's sciatica. What's causing it is a totally different question, and it's the one that actually matters.

So What's Actually Going On?

The sciatic nerve is the biggest nerve in your body. It comes from nerve roots that exit your low spine, then runs through your butt and down your leg. When something irritates or squeezes one of those roots, or the nerve itself somewhere along that path, you feel it down the leg.

That "something" can be a few different things. Sometimes it's a disc bulge or herniation sitting near a nerve root. Sometimes there's less room around the nerve than there should be, which we call stenosis. Sometimes the irritation is further down, deep in the hip and glute area. And sometimes there's no big structural problem at all. The nerve is just irritable, and it's reacting to how it's being loaded.

Here's why that matters. Two people can both say "I have sciatica" and need completely different plans. That's exactly why a generic exercise sheet so often does nothing. If nobody figured out what's driving it for you, you're basically guessing.

Why "Just Rest" Usually Backfires

I get why people do it. You've got pain shooting down your leg, it feels awful, and everything in you says stop moving. So you take it easy. Then a week turns into three, and you're stiffer, weaker, and honestly more scared to move than when you started.

The longer you avoid movement, the more your body deconditions, and the more sensitive and protective your nervous system gets. Most people do better when they stay as active as they can tolerate, with the right adjustments, instead of shutting everything down.

Now, I'm not saying grit your teeth and push through it. That's not it either. It's about figuring out which positions and movements calm things down, which ones fire it up, and building from there. Walking, certain hip and trunk work, and slowly adding load back in are often a big part of the answer.

What This Looks Like for Active People

The people we see aren't looking to be told to rest forever. They're golfers who can't make a full turn without a zing down the leg. Lifters who got scared of deadlifting. Runners who feel it ten minutes in. Parents who can't get down on the floor to play with their kids without paying for it later.

For them, the goal isn't just getting the leg pain to stop. It's figuring out what's behind it, getting back to moving without fear, and building the body up so it doesn't keep coming back.

That starts with a real assessment. How you move, what positions bring it on, how your hips and spine are sharing the load. Then a plan built around your life, with real guidance on what to do and what to avoid in the gym, on the course, and at home.

When You Shouldn't Wait

Most sciatica gets better with the right conservative care, but a few things mean don't wait around. If you notice your leg getting weaker, numbness in your groin or saddle area, or any change in your bladder or bowel control, get seen right away. Those need immediate medical attention.

You Don't Have to Just Live With It

If you've got pain shooting down your leg, you shouldn't have to guess what it means or give up what you love while you wait it out. Sciatica has a cause. Once you find it, you've got something to work with.
