Sciatica and nerve glides

Sciatica nerve glides should be gentle sliders, not hard stretches: they should move the nerve without sending stronger leg pain farther down the leg.

Sciatica is pain that travels down the leg — often past the knee into the calf or foot — because one of the nerve roots in your low back is being irritated, usually by a disc bulge or normal age-related changes. The pain can come with numbness, tingling, or pins-and-needles in a line down the leg. A lumbar nerve root (most often L5 or S1) gets compressed or chemically irritated where it leaves the spine. The leg symptoms follow that nerve's territory, which is why they run in a line and often go below the knee. Coughing, sneezing or straining briefly raises pressure on the nerve and flares the leg pain.

LEG-DOMINANT pain radiating below the knee in a dermatomal (line-like) pattern — more leg than back — from irritation of a lumbar nerve root (most often L5 or S1), often with numbness, pins-and-needles or tingling down one leg, and worse with coughing, sneezing or straining. That pattern is the guardrail for this page: it keeps the advice tied to the condition's symptoms and loading plan rather than to a generic body-part label.

New or worsening WEAKNESS in the leg — not just pain — is the one thing to get checked promptly, and so is numbness that's spreading or getting worse. And if you ever notice numbness around the saddle, groin or inner thighs, or any new trouble controlling your bladder or bowel, treat it as an emergency — go to A&E the same day, don't wait and don't try to sleep it off. If that does not fit, stay cautious and get the pattern checked.

Most sciatica settles — the nerve is irritated, not broken: Sciatica looks scary but the outlook is good: the large majority improve over 6 to 12 weeks, and surgery is rarely needed. The nerve is irritated, not damaged, and the body reabsorbs most disc bulges over time. Leg pain and tingling can be frightening, but hurting is not the same as harming — it's safe to keep moving within comfort. Use centralization to steer your exercises: Watch where your leg pain goes when you move. Movements that pull the pain back UP toward your spine (centralization — usually gentle backward bends) are GOOD: keep doing that direction. Movements that push the pain FURTHER down the leg (peripheralization) are the signal to ease off that direction.

For sciatica, move within comfort and follow centralization: keep directions that pull leg pain upward, and ease off directions that send it farther down the leg. That is the difference between useful modification and avoiding life until everything feels perfect.

The phase order matters. Start with calm: Calm the irritated nerve and find the gentle movements that ease your leg pain — easy gliding moves and the gentle backward bends that draw the pain up out of your leg, while staying active. Most sciatica settles, and hurting doesn't mean harm. Then move toward rebuild: Now that the leg pain is easing back toward your spine, build the core and hip strength that takes pressure off the nerve and steadies your back. Keep walking daily. The later target is back to the gym, where the payoff is lifting and sport, leg pain gone.

That lets you keep momentum while respecting the tissue. Do I need a scan or surgery? Usually neither. Most sciatica settles within weeks to a few months with activity and exercise. Scans often show disc bulges in pain-free people and rarely change treatment. Surgery is reserved for severe or progressing nerve problems that don't settle. Should I rest until the leg pain goes? No — staying gently active is part of the treatment. Bed rest slows recovery. Move within comfort, use your best (centralizing) direction, and build back up. Avoid the positions that send pain further down the leg.
