Disc involvement
Disc Bulge & Herniation — North Vancouver
Lifted something wrong, woke up with leg pain, or the MRI report finally landed. We figure out what the disc is actually doing and build a plan that respects it.
What it is
Understanding your disc bulge / herniation.
Discs are the load-distributing cushions between vertebrae. When one of them bulges, herniates, or starts to wear down, the surrounding structures — the joints, the nerves exiting the spine, the muscles trying to protect everything — all react. The pain you feel often does not come from the disc itself; it comes from a nerve root that the disc is now compressing, or from the joints and muscles working overtime to splint the area.
What people mean by 'disc problem' covers a wide range. A small bulge with localized back pain behaves very differently from a frank herniation pressing on the L5 nerve root and sending pain down the leg. Imaging findings also age along with you — a fair number of asymptomatic adults walk around with bulges they will never feel. Your symptoms, your movement, and your response to load matter more than what the MRI report says in isolation.
The reassuring part is that most disc-driven pain settles with conservative care. Some take weeks, some take longer. The unhelpful part is that not every protocol works for every disc — what calms one presentation can wind up another. The first assessment exists to figure out which set of movements is yours.
A related presentation worth naming: nerve root impingement. When a disc, a bone spur, or narrowing of the spinal canal (stenosis) presses on a specific nerve root, the symptoms follow that root's path — sharp pain, numbness, tingling, or weakness travelling into a defined area of the arm or leg. The treatment principles are the same as for disc-driven pain — find the position that takes pressure off the nerve, build tolerance for the positions you cannot avoid, and progress load as the nerve calms. Persistent or progressive weakness in a single muscle group is the signal to escalate care rather than continue conservative work in isolation.
What to expect
Many disc-related cases ease meaningfully within 4–8 weeks of consistent care. Full return to heavy lifting, running, or contact sport takes longer and depends on irritability, deficits at assessment, and whether radicular signs are clearing. Your physiotherapist will set the next milestone after the first visit.

Common questions
About disc bulge / herniation.
I have a herniation on MRI — do I need surgery?+
Usually not, at least not as a first step. Most disc herniations resolve or settle clinically with conservative care, even when the imaging looks dramatic. Surgical referral is reasonable when there is progressive neurological deficit, intractable pain that hasn't responded to a proper rehab trial, or red-flag findings. We'll be honest about which camp you're in.
Should I avoid bending and lifting entirely?+
No. Total avoidance keeps the spine deconditioned and the disc just as vulnerable when life eventually forces a lift. We coach a graded return to bending and lifting once the irritability is down. The goal is a back that handles loaded movement, not one that fears it.
Is McKenzie / extension the right approach for everyone?+
No. Extension-biased exercise helps a sub-group whose symptoms centralize with backward bending. Others do better with flexion or unloading positions. The directional preference test is part of why the first assessment matters.
Will the disc 'go back in'?+
Sometimes. Disc material can shrink or be reabsorbed over time, which is part of why many herniations look quieter on imaging months later. We don't bank on any specific imaging change — we measure progress by symptoms, movement, and load tolerance.
Do you direct-bill ICBC and extended health?+
Yes. Direct billing for most major extended-health insurers, plus ICBC and WorkSafeBC. We handle the paperwork.
