Introduction
Lower back pain is the single most common reason people walk into a physiotherapy clinic — and the most common reason they wait too long to do it. About 80% of adults experience it at some point, and for many Mississauga residents, it’s the dull ache that comes after a long commute, the sharp twinge when bending to tie a shoe, or the chronic stiffness that’s just become part of daily life.
The good news: most lower back pain is treatable, often without medication or surgery, when it’s addressed properly. The bad news: ignoring it almost always makes it worse. This guide breaks down what actually causes lower back pain, the evidence-based treatments that work, and when it’s time to stop pushing through and book an appointment at ReGen Physio & Wellness.
What Actually Causes Lower Back Pain?
Lower back pain isn’t a diagnosis — it’s a symptom. The cause can range from a one-time strain to a long-standing movement pattern that’s been quietly grinding down your spine for years. The most common culprits we see in clinic include:
Muscle and ligament strain
Lifting something awkwardly, twisting at the wrong angle, or sleeping in a bad position can strain the muscles and ligaments that support the spine. This is the classic “I just bent over to pick up a sock and now I can’t move” injury.
Disc-related issues
Bulging or herniated discs can press on nearby nerves, often causing pain that radiates down one leg — what most people call sciatica. Discs can also degenerate gradually with age, especially in people who sit for long hours.
Postural and movement dysfunction
Hours of sitting at a desk, driving, or hunching over a phone tightens the hip flexors, weakens the glutes, and forces the lower back to compensate. Over months and years, that compensation becomes pain.
Weak core and glute muscles
The lumbar spine isn’t designed to do all the work on its own. When the core and glutes aren’t pulling their weight, the low back picks up the slack — and eventually breaks down.
Other causes
Less commonly, lower back pain can stem from arthritis, spinal stenosis, sacroiliac joint dysfunction, or referred pain from the hips or pelvis. A proper assessment is what tells you which one is yours.

Acute vs. Chronic Back Pain: Why the Distinction Matters
Acute back pain comes on suddenly and lasts less than six weeks. It usually has a clear trigger — a lift, a fall, a long flight — and responds well to short-term treatment.
Chronic back pain lasts longer than three months and usually has a more complex picture: postural issues, muscle imbalances, nervous system sensitization, or a structural change that’s been ignored for too long.
The treatment plan looks different for each. Acute pain often needs hands-on care, gentle mobility work, and a quick return to movement. Chronic pain typically needs a longer-term program focused on strength, motor control, and rebuilding tolerance to load. Both respond to physiotherapy — but treating chronic pain like an acute strain is one of the biggest reasons people stay stuck for years.
When to See a Physiotherapist
Some lower back pain settles on its own within a few days. Most doesn’t. You should book an appointment if:
- The pain has lasted more than a week without clear improvement
- It’s interfering with sleep, work, or daily activities
- You feel pain, numbness, or tingling that radiates down a leg
- You’ve had repeated flare-ups of “the same” back pain
- You’re avoiding movement because you’re afraid of making it worse
- You’ve been told to “just rest” but the rest isn’t helping
- You’re considering imaging or injections and want a conservative option first
Seek immediate medical attention if you experience loss of bladder or bowel control, severe leg weakness, numbness in the groin or inner thighs, or back pain following a serious fall or accident. These are red flags that require emergency assessment.
For everything else, physiotherapy is the first-line, evidence-based treatment.
How Physiotherapy Treats Lower Back Pain
There’s no single technique that fixes every back. A good physiotherapy plan combines several approaches based on what your assessment reveals.
1. Manual therapy
Hands-on techniques like joint mobilizations, soft tissue release, and trigger point work can reduce pain and improve mobility in the short term. These create the window of opportunity to do the longer-term rehab work.
2. Targeted exercise
This is the part that actually changes things. Exercise programs for low back pain focus on:
- Core stability — not crunches, but deep core control through movements like dead bugs, bird dogs, and Pallof presses
- Glute strength — bridges, hip thrusts, and single-leg work to take load off the lumbar spine
- Hip mobility — opening up tight hip flexors and improving rotation
- Movement re-education — learning to hinge, squat, and lift with proper mechanics
3. Education and load management
Knowing what to do (and not do) outside the clinic matters as much as the treatment itself. You’ll learn how to sit, sleep, lift, and move in ways that stop reinjuring the area.
4. Adjunct therapies
Depending on your case, your plan might include:
- Massage therapy to release chronically tight muscles and improve circulation
- Chiropractic care for joint-specific mobility issues, often coordinated alongside physiotherapy
- Modalities like ultrasound, TENS, or heat for short-term symptom relief
At ReGen Physio, all of these services are available under one roof, which makes coordinated care simple.
What to Avoid When You Have Back Pain
A few common habits make most back pain worse:
- Prolonged bed rest — research is clear that staying active (within tolerance) recovers faster than resting
- Heavy lifting without preparing the body — especially deadlifts, awkward overhead lifts, or one-sided loads
- Sitting for hours without breaks — set a timer and stand every 30 to 45 minutes
- Sleeping on your stomach — it forces the low back into extension all night
- Pushing through sharp pain in the gym — there’s a difference between productive discomfort and a flare-up
How Long Does Recovery Take?
It depends on what’s going on. Rough estimates from our experience treating lower back pain in Mississauga:
- Acute muscular strain: 2–4 weeks with active treatment
- Disc-related pain (no surgery): 6–12 weeks
- Chronic mechanical back pain: 8–16 weeks with a consistent program
- Post-surgical rehab: 3–6 months depending on the procedure
Consistency matters more than session frequency. Patients who do their home exercises four or five days a week recover faster than those who rely only on what happens in clinic.
Frequently Asked Questions
Can physiotherapy fix a herniated disc?
Physiotherapy can’t physically push a disc back into place, but it can effectively treat the pain and dysfunction caused by a herniation. Most disc-related pain resolves with conservative treatment over 6–12 weeks, and surgery is rarely the first option.
Should I use heat or ice on lower back pain?
For new, acute injuries with inflammation, ice can help in the first 24–48 hours. For chronic stiffness and muscle tension, heat is usually more useful. When in doubt, choose whichever feels better — both are safe in moderation.
Can I keep working out with lower back pain?
Often yes, with modifications. Avoiding all activity usually slows recovery. A physiotherapist can help you adjust your training — swapping a deadlift for a hip hinge variation, reducing load, or changing tempo — so you can keep moving while the back heals.
Is chiropractic care or physiotherapy better for back pain?
They’re complementary, not competing. Chiropractic care often focuses on joint-specific adjustments; physiotherapy combines manual therapy with rehab exercise and movement re-education. Many patients benefit from both, which is why our Mississauga clinic offers them together.
