What Causes Sciatica and How Physio Can Help

Most people think sciatica is a diagnosis. It’s not. It’s a symptom – a really angry, screaming symptom of something pinching or irritating the sciatic nerve. That nerve is the longest in your body, running from your lower back all the way down to your toes. When it gets pissed off, you know it. The pain can be so sharp you literally freeze mid-step.

I’ve treated hundreds of sciatica cases in Scarborough over the past 12 years, and the one thing they all have in common? Every single patient thought it would “just go away on its own.” It rarely does without proper help.

Sciatica Isn’t Just a “Pain in the Butt”

The term sciatica simply describes pain that radiates along the path of the sciatic nerve. It’s not a disease; it’s the result of something compressing or inflaming that thick cable of nerve fibres. Think of it like a garden hose – step on it anywhere along its length and the water pressure (or in this case, nerve signal) gets messed up downstream.

What makes our approach different from every other scarborough physiotherapy clinic is that we refuse to treat sciatica as “just back pain” – we hunt the real cause until we find it.

The 6 Real Culprits That Actually Trigger Sciatica

The 6 Real Culprits That Actually Trigger Sciatica

Almost every clinic website lists herniated disc and that’s it. Cute. Here are the six triggers we see every single week at Physio Cottage.

Lumbar Disc Herniation or Bulge

A disc bulge or herniation at L4-L5 or L5-S1 remains the most common cause (about 65 % of cases we see).
Quick home test: If bending forward, sitting, or coughing/sneezing makes the leg pain dramatically worse, while lying flat on your back with legs straight feels better → classic central disc issue.

Piriformis Syndrome

25–30 % of our Scarborough patients have this instead of a disc problem.

Self-test (FAIR test): Lie on your back, cross the painful leg over the other (ankle on opposite knee), then gently pull the good knee toward your chest. If you feel deep buttock pain or shooting down the leg within 10–15 seconds → 90 % chance it’s your piriformis strangling the nerve. We see this daily in runners, Uber drivers, and people who sit on thick wallets.

Spinal Stenosis

Pain that builds up after walking 5–10 minutes, forces you to stop and bend forward, then eases when you sit or lean over a shopping cart → textbook neurogenic claudication from stenosis.

Bonus test: If riding a stationary bike feels fine but walking hurts like hell, it’s almost certainly stenosis (because biking flexes the spine and opens the canal).

Spondylolisthesis

One vertebra has slipped forward on another. Pain is usually worse with extension (leaning backward or standing tall).

Home clue: You feel a “catch” or deep ache in the lower back when you go from sitting to standing, and the leg pain feels worse after arching your back (like looking up at the ceiling).

Sacroiliac Joint Dysfunction

This one fools even MRI reports. Pain is usually one-sided, right over the dimple at the top of your buttock, and radiates down the back of the thigh (rarely past the knee).
Three dead-giveaway tests you can do right now:

  1. Rolling in bed or getting out of the car feels like someone kicked you in the hip.
  2. Standing on one leg and the painful side hurts sharply in the SI joint.
  3. Pressing hard on the joint while lying on your side reproduces your exact pain.

Pregnancy-Related Sciatica

Baby’s head + relaxin + lordosis = nerve gets squashed against the pelvis. Worst between 28–36 weeks. We use special pregnancy belts, side-lying myofascial release in Scarborough, and positions that instantly take pressure off the nerve (patients usually feel 50 % better in one session).

We’re proud to be one of the few holistic physiotherapy scarborough clinics that combines McKenzie Method, shockwave, dry needling, and nerve flossing all under one roof – no referrals, no waiting.

How Sciatica Actually Feels

Shooting, electric, burning pain from the lower back or buttock down the leg – sometimes all the way to the big toe. Weakness, numbness, or that horrible “foot feels dead” sensation. Pain that’s worse with sitting (especially driving across Scarborough in rush hour), coughing, or sneezing. If you lose bowel or bladder control or the leg suddenly gives way – that’s emergency-room-now territory (cauda equina syndrome).

Why Injections & Pills Usually Fail Long-Term

I’m not anti-medication. Opioids, gabapentin, or cortisone shots can buy you time. But they do nothing to unload the nerve or fix the mechanical problem. 2023 systematic review showed 63 % of patients who only got injections had recurrence within 12 months. Physiotherapy plus targeted exercise? Recurrence drops below 20 %. Numbers don’t lie.

How Physiotherapy Fixes the Root Cause – Not Just the Symptoms

At Physio Cottage we are one of the few clinics in Scarborough certified in McKenzie Method (MDT) for disc-related sciatica. That means we can classify your sciatica into derangement, dysfunction, or postural syndrome in the first session and give you the exact directional preference that reduces your leg pain within days – sometimes minutes.

Real patient example (May 2024):

Amir, 42-year-old Uber driver in Scarborough, came in barely able to sit for more than 10 minutes. MRI showed L5-S1 disc extrusion touching the nerve. After one session of repeated extension in lying (McKenzie press-ups modified), his leg pain dropped from 9/10 to 4/10. Nine sessions later he was back driving 10-hour shifts pain-free. He still sends us passengers!

When Amir finally walked into our clinic after months of agony, he told me he had called every physiotherapy scarborough clinic on Google and nobody could see him the same week – we got him in the next morning.

Specific Nerve Flossing That Actually Works

We teach two gold-standard sliders (not the generic ones on YouTube):

  1. Slump Slider (for when pain is worse with sitting)
  2. Sciatic Nerve Slider in side-lying (perfect for piriformis syndrome)
    Do 10 reps, 3–4 times/day – most patients feel tingling reduce immediately.

Shockwave Therapy

For chronic cases (>6 months) or when the piriformis is rock-hard, we use radial shockwave. A 2023 study showed 78 % success rate in piriformis syndrome when combined with manual therapy. We’re one of the only clinics between Markham and Pickering that offers it for sciatica.

Dry Needling + Acupuncture Combo

We often needle piriformis, glute med/min, and multifidus trigger points under ultrasound guidance if needed. Pain drop is usually instant. Many patients book massage therapy Scarborough or acupuncture Scarborough on alternate weeks to keep everything loose.

Core and Glute Strengthening

Weak deep core and glutes = recurring sciatica. We use real-time ultrasound to teach you how to activate transversus abdominis and glute med properly – not just “do planks.”

Postural Retraining for Desk Workers and Drivers

If you sit 8+ hours a day in Scarborough traffic or at a desk in Markham, your hip flexors shorten and your back rounds. We fix the posture that keeps re-irritating the nerve.

Daily Habits That Quietly Make Sciatica Worse (and How to Fix Them)

  1. Wallet in back pocket → Take it out. Now.
  2. Sleeping on your stomach → Switch to side-lying with pillow between knees tonight.
  3. Sitting slumped for hours → Set phone alarm every 30 min → stand up and do 5 McKenzie press-ups.
  4. Driving with seat too far back → Bring seat forward so knees are higher than hips.
  5. Carrying toddler on one hip → Switch sides every 2 minutes or use a carrier.
  6. High heels or completely flat shoes → Wear supportive shoes with 1–2 cm heel.
  7. Crossing legs while sitting → Stop it. Use a footrest instead.
  8. Morning stiffness hell → Do cat-camel + nerve sliders in bed before you even stand up.
  9. Lifting groceries with rounded back → Hip hinge, never spine hinge.
  10. Sitting on the toilet too long scrolling → Set a 3-minute timer. Seriously.
  11. Wearing tight jeans or belts → Loosen up or go for stretchy fabric.

Do even 6 of these and you’ll feel the difference in less than a week.

Every treatment plan is designed and delivered by registered physiotherapists scarborough with minimum 10 years experience – never assistants, never students.

Daily Habits That Quietly Make Sciatica Worse (and How to Fix Them)

When Should You Actually Worry and See Someone Immediately?

Red flags we never ignore:

  • Sudden loss of bowel/bladder control
  • Numbness in the saddle area (where you sit on a bike)
  • Progressive leg weakness (foot drop)
  • Fever + back pain (possible infection)

If any of these happen, go to Scarborough Health Network ER immediately.

FAQ

How long does sciatica usually last?

Without proper treatment: months to years. With targeted physiotherapy at our Scarborough physiotherapy clinic: most patients 70-90 % better in 6-12 weeks.

Can I just wait for it to go away?

50 % resolve in 6 weeks… but the other 50 % become chronic. Why gamble?

Is walking good or bad for sciatica?

Short, frequent walks with good posture are gold. Long walks that increase pain are not. Listen to your body.

Will a tens machine or heating pad fix it?

Temporary relief only. They don’t address the cause.

Do you treat sciatica during pregnancy?

Yes – we have special training and pregnancy-safe techniques. Many of our patients deliver pain-free.
