Sciatica Relief in Calgary: What It Actually Is and How Physiotherapy Helps in 2026

If you have an electric, burning pain that travels from your low back or buttock down the back of your leg — sometimes past the knee, occasionally into the foot — and it gets worse when you sit, sneeze, or bend forward, you are probably looking up the word sciatica. You are not imagining it, you are not exaggerating it, and it is not "just" a tight muscle. Sciatica is one of the most common reasons adults in Calgary end up in our clinic, and the good news is that the evidence in 2026 is clearer than ever: most people get meaningfully better with the right physiotherapy plan, without injections, opioids, or surgery.

This article is the patient-facing guide we wish every person walked in with. It covers what sciatica actually is, what causes it, what the imaging and research really show, and what an evidence-based physiotherapy plan looks like at MSK Rehabilitation on Macleod Trail in south Calgary.

What Sciatica Actually Is (and Isn't)

"Sciatica" is not a diagnosis — it is a description. It refers to pain that follows the path of the sciatic nerve, the largest nerve in the body, which is formed by nerve roots from the lower lumbar and upper sacral spine (L4 through S3). True sciatica is radicular pain: pain caused by irritation or compression of one of those nerve roots. It usually travels below the knee, often follows a specific stripe down the leg, and can come with numbness, pins-and-needles, or weakness in the foot or ankle.

Not every leg pain that comes from the back is sciatica. Referred pain from the lumbar joints, discs, or sacroiliac joint can feel similar but tends to stay in the buttock or thigh, feel deeper and more achy, and not follow a clear nerve pattern. That distinction matters because the treatment plan is different. A good physiotherapy assessment sorts this out on the first visit.

What Causes Sciatica

The most common cause of true sciatica in adults is a lumbar disc herniation — typically at L4-L5 or L5-S1 — where displaced disc material chemically and mechanically irritates a nerve root as it exits the spine. Other common causes include:

·       Lumbar spinal stenosis — age-related narrowing of the spinal canal or nerve root openings, more common after age 60, classically causing leg pain that worsens with standing and walking and eases with sitting or leaning forward.

·       Spondylolisthesis — when one vertebra slips forward on another, narrowing the space the nerve roots travel through.

·       Foraminal stenosis or facet arthropathy — degenerative changes that crowd a specific nerve root.

·       Piriformis syndrome — when the sciatic nerve is irritated as it passes near or through the piriformis muscle in the buttock. It is real, but it is also chronically overdiagnosed; in most people with buttock-and-leg pain, the problem is coming from the spine, not the piriformis.

·       Pregnancy-related sciatica — usually a combination of postural load, pelvic mechanics, and deep gluteal muscle tension rather than a true disc compression. Almost always self-limiting and very responsive to physiotherapy.

What MRI Findings Actually Mean

If you have already had an MRI, you may have read a report mentioning a "bulging disc," "herniation," "degenerative changes," or "nerve root contact." Before you panic: in a landmark systematic review of imaging in over 3,000 pain-free adults, Brinjikji and colleagues (2015) showed that disc bulges, protrusions, annular fissures, and degenerative changes are common findings in people with no back or leg pain at all — and become more common with age. By age 50, roughly 60% of pain-free adults have disc degeneration on MRI; by age 80, that number is over 95%.

Translation: an MRI finding is a piece of the puzzle, not the whole story. What matters clinically is whether the imaging matches your symptoms, your physical exam, and your function. That is exactly what a thorough physiotherapy assessment is for.

The Natural History Is Reassuring

One of the most important conversations we have on day one is about prognosis. In a large systematic review and meta-analysis by Chiu and colleagues (2015), roughly one third of people with sciatica had clear improvement within two weeks, and about three quarters had improved by 12 weeks. Even disc herniations on imaging tend to shrink or resorb over time, particularly the larger extruded ones.

That does not mean "do nothing and wait." A meaningful minority of people — around 20-30% — still have significant symptoms at one year if their problem is not actively managed. The point of physiotherapy is to make recovery faster, more complete, and less likely to recur.

Surgery vs Conservative Care: What the Trials Show

In carefully selected patients with disc-related sciatica that has not improved with 6-12 weeks of non-surgical care, microdiscectomy can produce faster relief in the first few months. The classic Peul et al. (2007) trial in the New England Journal of Medicine and the long-term SPORT trial (Lurie et al.) both showed faster early improvement with surgery — but, importantly, by one to two years the outcomes between operated and non-operated groups converge. At 4 to 10 years out, most differences disappear entirely. Surgery is a legitimate option for the right patient at the right time — typically progressive weakness, intractable pain, or bowel/bladder involvement — but it is not the inevitable destination for most cases of sciatica.

Pills That Do Less Than People Think

A lot of patients arrive on pregabalin (Lyrica) or gabapentin (Neurontin), often prescribed specifically for their sciatica. The 2017 SCIATICA trial by Mathieson and colleagues — a high-quality randomized controlled trial published in the New England Journal of Medicine — compared pregabalin to placebo for sciatica and found no benefit on leg pain at 8 or 52 weeks, with significantly more side effects (dizziness, drowsiness) in the pregabalin group. Opioids are even less defensible — they don't fix the nerve root problem and bring real risks. The current evidence pushes us toward activity, education, and skilled physiotherapy, with medication as a short-term bridge at most.

What Evidence-Based Sciatica Physiotherapy Actually Looks Like

1. A real assessment, not a guess

We confirm whether your pain is actually radicular (nerve root), referred (joint/disc), or peripheral (piriformis, deep gluteal, hamstring). We test reflexes, strength, sensation, and nerve mobility. We screen for the small percentage of cases that need urgent imaging or referral — progressive neurological loss, saddle anesthesia, bowel or bladder changes — and we are direct with you if we find them.

2. Directional preference and graded loading

Most disc-related sciatica responds to a specific direction of movement (often extension/press-ups) that "centralizes" the pain — meaning the leg pain retreats toward the back, even before it improves overall. This is the McKenzie / Mechanical Diagnosis and Therapy approach, and the UK NICE guidelines (NG59) support tailored exercise as a first-line treatment for low back pain and sciatica.

3. Manual therapy and neural mobilization

As a Fellow of the Canadian Academy of Manipulative Physiotherapy (FCAMPT), I use targeted hands-on techniques — joint mobilization, soft tissue work, neural "sliders" and "tensioners" — to reduce guarding and improve nerve mobility, layered alongside exercise. Manual therapy is a tool, not the whole program.

4. Progressive strength and motor control

Once the acute irritation calms, the work shifts to building hip, gluteal, and trunk capacity so the lumbar spine has support when you load it. This is where most generic clinic programs stop short — and where re-injury rates climb.

5. Education that actually reduces fear

Pain neuroscience education has good evidence for reducing disability and catastrophizing in persistent back and leg pain. Understanding why your nerve hurts — and what is and isn't dangerous — changes how you move.

Frequently Asked Questions About Sciatica

How long does sciatica usually last?

About one third of cases improve significantly within two weeks, and roughly three quarters improve by 12 weeks (Chiu et al., 2015). A minority — around 20-30% — still have meaningful symptoms at one year without active treatment, which is exactly why early, targeted physiotherapy matters.

Should I get an MRI before starting physio?

Usually no. Imaging is not required to begin treatment and is more useful for cases that are not improving, that show progressive neurological loss, or where surgery is being considered. Brinjikji et al. (2015) showed that disc bulges and degenerative changes are common in pain-free adults — an MRI without context can scare patients more than it helps them.

Is walking good or bad for sciatica?

For most people, walking is helpful as long as it does not increase leg pain or neurological symptoms. Prolonged sitting and forward bending tend to be worse for disc-related sciatica. We tailor specific advice in your assessment.

Will I need surgery?

Most likely not. Trials such as Peul et al. (2007) and the SPORT trial show that operated and non-operated groups converge by one to two years, and most cases of sciatica resolve with conservative care. Surgery is reserved for progressive weakness, intractable pain, or cauda equina symptoms (bowel/bladder changes, saddle numbness).

Does pregabalin or gabapentin work for sciatica?

The high-quality SCIATICA trial (Mathieson et al., 2017, NEJM) showed no benefit of pregabalin over placebo for sciatica at either 8 or 52 weeks, with significantly more side effects. Current evidence does not support routine use of these medications for sciatica.

Is it really sciatica, or is it something else?

True sciatica follows a specific nerve-root pattern, usually travels below the knee, and may come with numbness or weakness. "Referred" pain from joints, discs, or muscles can mimic it but stays more localized in the buttock or thigh. Sorting that out is one of the first things we do in your assessment.
