Short answer: sciatica describes pain that travels along the path of the sciatic nerve — usually into the buttock, down the back of the thigh, sometimes past the knee — rather than a diagnosis in itself. Most cases settle over weeks to months. A proper assessment establishes whether the nerve is genuinely involved, rules out the small number of presentations that need urgent medical attention, and identifies what can reasonably be done.

What it usually looks like

People describe it differently from ordinary back pain, and the difference is usually the point. It travels. It can be sharp or electric rather than achy, and it often follows a line you could trace with a finger — through the buttock, down the back of the thigh, sometimes into the calf or foot.

Sitting frequently makes it worse. So does the first movement after sitting. Some people find they cannot get comfortable in any position at night, which is often what finally prompts the call. There may be pins and needles, numbness, or a leg that feels heavy or unreliable.

It is worth saying plainly: leg symptoms are worth getting assessed rather than waiting out, because the assessment is partly about ruling things out.

What the research actually supports

Sciatica is a symptom pattern, not a cause. The underlying driver varies — nerve root irritation is common, and a range of structures can contribute. This matters because the honest answer to “what is causing mine” is often that it cannot be pinned to one structure with confidence, and treatment does not necessarily depend on doing so.

The imaging picture is the same as for back pain generally, and it surprises people. A 2015 systematic review in AJNR found disc bulges in roughly 30% of people aged 20 with no symptoms at all, rising to about 84% by 80, and disc protrusions in around 29% of asymptomatic 20-year-olds. Finding something on a scan does not establish that it is the cause of your symptoms. NICE guidance advises against routine imaging outside specialist settings, and recommends it only where the result would change management.

On treatment, NICE addresses sciatica directly and its position is worth quoting in substance: manual therapy — spinal manipulation, mobilisation or soft tissue technique — should be considered as part of a treatment package including exercise, rather than delivered alone. That is the model we work to, and it is why an assessment here produces an exercise and self-management plan rather than only hands-on treatment.

The broader evidence on spinal manipulative therapy is modest and honest: a 2019 review in the BMJ covering 47 trials and over 9,000 people concluded it produces effects broadly similar to other treatments recommended in clinical guidelines. Mild temporary soreness afterwards is common. Serious complications have been reported and are rare, though the literature cannot establish a reliable rate.

Sciatica and a long commute

Prolonged sitting is one of the few factors research has consistently associated with low back pain recurrence, and sitting is also the position most people with sciatica find hardest. In a city where around 4,500 more people live here than work here — most of them driving twenty to forty minutes each way on Highway 1 or 17 Ave SE, then sitting at a desk between those drives — that combination comes up often.

If your leg symptoms are manageable in the morning and difficult by the evening commute, that pattern is useful diagnostic information rather than just bad luck. Bring it up at the assessment.

How we assess it

About 45 to 60 minutes, most of it assessment.

  • History. Where the symptoms travel, how far down, what brings them on, what settles them, and whether anything has changed recently — that last one matters most.
  • Neurological screening. Reflexes, muscle strength and sensation, to establish whether there is genuine nerve involvement rather than referred pain, and to check nothing is progressing.
  • Orthopaedic testing and movement assessment. Including which positions and directions provoke or relieve the leg symptoms.
  • ProAdjuster scan where appropriate. A computerised instrument measuring how individual spinal segments are moving.
  • Onward referral where that is the right call. Not every presentation belongs in a chiropractic office, and you will be told straight if yours does not.

When to seek medical attention urgently

Some symptoms need same-day medical assessment rather than a chiropractic appointment. Numbness in the groin, buttocks or inner thighs; loss of bladder or bowel control; or weakness in both legs can indicate cauda equina syndrome, which is a medical emergency. Progressive or worsening weakness in a leg, unexplained weight loss alongside these symptoms, fever, or onset following significant trauma also warrant prompt medical review.

If any of these apply, contact a physician or attend an emergency department rather than booking here.

Common questions

Is sciatica the same as a slipped disc?

No. Sciatica describes the symptom pattern. Disc involvement is one possible contributor among several, and imaging findings are common in people with no symptoms at all, so the two are not interchangeable.

Will it go away on its own?

Many cases improve over weeks to months. That is not a reason to avoid assessment, particularly where there is numbness or weakness, because part of the value of an assessment is establishing what you are dealing with.

Should I keep moving or rest?

Guidelines favour staying active within the limits of your symptoms over bed rest. What that looks like in practice differs with sciatica compared to ordinary back pain, which is part of what an assessment is for.

Do I need an MRI?

Usually not initially. Guidelines recommend imaging where it would change management or where specific clinical concerns exist. If that applies to you, you will be told.

Do I need a referral to book?

No. Chiropractors are primary contact practitioners in Alberta.

Is it covered?

Not by Alberta Health Care. Many extended health plans include chiropractic coverage; we provide receipts for submission.

Booking an assessment

New patient assessment — $67. Includes health history, physical and neurological examination, ProAdjuster scan where appropriate, and a written summary of findings. Available to patients who have not previously attended a Divine Spine clinic. Imaging, if clinically indicated, is referred out and billed separately by the imaging facility.

If you are unsure whether this is the right place for your symptoms, a ten-minute call costs nothing and commits you to nothing — and if it is not, we will tell you where to go instead.
