Sciatica treatment in Montreal starts by naming the cause
Sciatica describes pain running from the buttock down the leg along the sciatic nerve. It is a pattern, not a diagnosis, and several tissues imitate it convincingly. The examination works out which one is producing your line of pain, because a disc, a joint and a tight muscle each need something different.
A disc pressing on a nerve root is the classic cause, and it usually behaves predictably: worse sitting, worse with coughing or sneezing, and reproduced when the straight leg is raised to a particular angle. The angle itself gets written down, because it is the number the retest is measured against.
The hip joint, the sacroiliac joint and the gluteal muscles all refer pain into the thigh and none of them is a nerve problem. The piriformis sits directly over the nerve and can irritate it without any disc involvement, which is why soft tissue work helps some people and does nothing for others.
Reflexes, strength and sensation decide between them. Where the testing points at the disc, decompression is one option considered. Where it points at the joint or the muscle, it is not, and the disc page explains why that distinction changes everything.

The examination
How sciatica is examined in Montreal
Map the line
Where the pain starts, how far down it travels, and whether it stops above or below the knee.
Straight-leg test
The angle at which symptoms appear, compared with the other side, which separates nerve from muscle.
Reflex and strength
Ankle and knee reflexes with a strength check, to establish whether a nerve root is genuinely involved.
Plan and retest
What is proposed, and the retest that decides whether it continues rather than a booked course.
Honest limits
What improvement in sciatica actually looks like
Progress usually shows as the pain retreating up the leg rather than fading evenly. Calf symptoms quiet first, the thigh next, and the buttock last. That direction matters more than the daily score and it is what gets asked about between visits, even in a week that felt no better overall.
Sitting loads the lower discs more than standing does, so a long drive can undo a good morning. Practical instructions about seat position and breaks are part of the plan, not an afterthought, and they sit alongside what to do at home.
A foot dragging more as the hours pass, numbness around the saddle area, or loss of bladder control is an emergency, not an appointment. So is a calf that is swollen, warm and tender. The red flags page lists them, and the re-assessment point is fixed in advance.

What sciatica overlaps with
The conditions that imitate this one and the reading that goes with it.
Anything specific to you belongs in the examination rather than on a page.
It is a description of a pattern rather than a cause. The useful question is which structure is irritating the nerve, because a disc, a joint and a tight muscle all produce that line and all respond differently.
Sitting raises the pressure inside the lower discs and shortens the muscles at the back of the hip. If a disc is part of your picture, a long drive is one of the harder things you can ask of it.
Be careful. If the nerve itself is irritated, aggressive hamstring stretching pulls on the structure that already hurts. Which stretches apply depends on what the examination finds, so ask before adding them.
It may reduce pain and improve walking for some disc-related cases. It does not guarantee the irritation will disappear, and it is only considered when the testing actually points at a disc.
Some people feel a difference within a couple of sessions and others take weeks. The retest decides, which is why the straight-leg angle is measured again rather than relying on how the week felt.
Usually yes, within what does not increase the leg symptoms. Walking is generally tolerated well. What to avoid for now depends on which direction reproduced your pain during the examination.
Not usually at the start. Imaging changes the plan only in specific situations, and it often shows disc findings that are present in people with no leg pain at all. The exam decides whether it would alter anything.
Severe pain arriving in both legs at once needs assessment the same day rather than an appointment, particularly alongside any change in bladder control or numbness around the saddle area.
