If you’re dealing with that deep, nagging pain in your lower back or leg, the kind that shoots down and makes sitting, walking, or even relaxing a challenge, there’s a good chance it’s sciatica. And if you’ve been Googling solutions or trying to stretch it out on your own without much luck, you’re not alone. At Simply Physio, we help people in this exact spot every day. The good news: you don’t have to just “live with it.” Physical therapy for sciatica can get you out of pain and back to living your life, without needing medication, injections, or anything scary.
What exactly is sciatica?
Sciatica isn’t actually a condition itself, it’s a symptom. It happens when something puts pressure on your sciatic nerve, which runs from your lower back down through your hips, glutes, and into each leg. That pressure causes pain, tingling, numbness, or weakness in the leg, depending on how irritated the nerve is. Some people feel a dull ache; others get a sharp, burning pain that stops them in their tracks. It really depends on where the nerve is being squeezed, and by what.
What’s going on in your body
The sciatic nerve is a big one: it starts in your lower spine, travels through your pelvis, and splits into two branches going down each leg. Because it touches so many bones, discs, and muscles along the way, a lot of things can affect it, which is why sciatica pain shows up so differently from person to person. Understanding what’s actually putting pressure on the nerve is the key to fixing it, and that’s the focus of physical therapy.
Common causes of sciatica
Herniated discs are at the top of the list: when a spinal disc slips or breaks down, it can press on the nerve. Spinal stenosis, where the space around the nerve narrows and crowds it, is another common cause, along with piriformis syndrome, a tight muscle deep in the glutes that squeezes the nerve. People who sit a lot, lift heavy things with poor form, or don’t stretch regularly are more at risk, and injuries, arthritis, or general wear and tear can all play a role too. Often it’s a combination: tight hips, a weak core, poor posture, a bit of inflammation, all adding up.
Should you get it checked out?
If sciatica pain is minor and goes away after a few days, great. But if it sticks around, keeps coming back, or starts interfering with walking, sleeping, or getting comfortable, it’s time to see someone. We’ve seen people wait too long and end up compensating so much they create new problems elsewhere. If you notice tingling, weakness, or numbness in your leg, or you feel like you can’t trust your leg to hold your weight, that’s a sign your body needs help. A few red flags warrant an ER visit right away: trouble with bladder or bowel control, numbness in the groin, or sudden loss of control in your legs.
How physical therapy actually helps
Sciatica treatment isn’t just about easing pain, it’s about figuring out what’s causing the nerve irritation in the first place, and fixing that. We don’t do cookie-cutter treatment plans: we start with a real assessment to figure out whether it’s a disc issue, a muscle imbalance, or a posture problem, then build a plan that fits your body and your life. Early on, the goal is pain relief through gentle stretches, hands-on therapy, and guidance on moving in ways that don’t aggravate the nerve. As things improve, we add strengthening and mobility work, especially for the core, hips, and back, so you’re less likely to flare up again. Along the way, we teach you the “why” behind everything: how to sit, lift, and walk in ways that protect your back without giving up the things you love.
How to keep sciatica from coming back
Once the pain’s gone, prevention keeps it that way. If you sit a lot for work, set a timer to stand and stretch every 30–45 minutes. Learn to lift with your legs, not your back. Strengthen your core, glutes, and lower back to support your spine, and move more, sit less. Even things like your mattress, shoes, and work setup can make a difference: small imbalances add up to big problems over time, so we help you spot the weak spots and fix them before they flare up again.
