Causes of Lower Back Pain in Mississauga — And Why It Keeps Coming Back
Lower back pain is one of the most common reasons people seek back pain treatment in Mississauga, yet many patients are told “nothing is wrong” after imaging or standard care. At Redux Movement, we see this every day.
Lower back pain isn’t just about tissues — it’s about how your body moves, loads, and compensates over time. When the root cause isn’t identified, pain returns even after rest, ultrasound, or MRI scans.
This is why our approach is assessment first, followed by precision treatment designed to deliver meaningful results from day one.
Mechanical & Movement-Based Causes of Lower Back Pain
One of the most overlooked contributors to lower back pain is mechanical stress. This means the pain comes from how the spine and surrounding structures are being used — not necessarily damaged.
Common mechanical causes we see in Mississauga include:
Prolonged sitting at work
Poor lifting mechanics at the gym or job
Repetitive bending and twisting
Weak core and glute muscles
These issues often explain lower back pain hurting when sitting, especially during long desk hours or driving. When the spine is repeatedly loaded in the same positions, tissues become irritated even without structural injury.
This is why many patients with lower back pain hurting when standing or walking feel stiff or sharp pain despite “normal” imaging.
Muscle & Myofascial Pain (Pain Imaging Often Misses)
A large percentage of patients with persistent pain have muscle-based or fascial pain, which does not show up on ultrasound or MRI.
This is especially common in people searching for:
unexplained lower back pain that the doctor says nothing is wrong
back pain hurting even after getting ultrasound and MRI
Muscles such as the quadratus lumborum, erector spinae, and deep stabilizers can develop trigger points and tension patterns that refer pain into the lower back, hips, or legs.
At Redux Movement, this is where manual therapy and back pain acupuncture in Mississauga play a powerful role by:
Reducing muscle guarding
Improving blood flow
Resetting pain signals
Restoring normal movement patterns
Disc & Nerve-Related Lower Back Pain
Disc irritation and nerve sensitivity don’t always present as extreme pain — sometimes they appear as stiffness, aching, or intermittent sharp discomfort.
This can explain:
lower back pain hurting when sleeping
pain that worsens when rolling in bed
morning stiffness that improves with movement
Nerve-related lower back pain may also cause symptoms such as:
Numbness or tingling
Pain that changes with posture
Our assessments focus on distinguishing disc irritation vs muscle-driven pain, which is essential for effective treatment.
Lower Back Pain After a Fall or Impact
Back pain from falling down is another common reason people seek care — even weeks or months after the incident.
Falls can cause:
Joint irritation
Movement avoidance patterns
Even if X-rays or scans show no fracture, the nervous system can remain sensitized. Without addressing this properly, pain becomes chronic and movement confidence declines.
Lifestyle Factors That Make Lower Back Pain Persistent
Lower back pain rarely exists in isolation. It’s often influenced by:
Sleep positions and mattress quality
Stress and nervous system overload
Lack of recovery between workouts
Poor breathing and bracing strategies
Patients commonly report lower back pain hurting when sleeping, especially when tissues remain irritated overnight or when spinal stability is compromised.
Why Imaging Alone Doesn’t Explain Back Pain
Many patients are frustrated after being told:
“Your MRI looks normal.”
Pain is not always caused by visible damage. Instead, it often comes from:
Movement inefficiency
Tissue overload
Poor neuromuscular coordination
This is why back pain treatment in Mississauga must go beyond passive modalities and focus on how your body actually functions.
Our Approach at Redux Movement
At Redux Movement, we take a root-cause approach to lower back pain treatment. Every session begins with a detailed assessment that looks at:
Movement patterns
Load tolerance
Muscular balance
Nervous system sensitivity
Based on findings, treatment may include:
Back pain acupuncture in Mississauga
Corrective movement strategies
Education to prevent recurrence
Many patients notice improvement from their first visit, not because pain is masked — but because the right structures are treated.

Frequently Asked Questions About Lower Back Pain
What causes lower back pain even when scans are normal?
Lower back pain can be caused by muscle tension, joint irritation, movement dysfunction, or nervous system sensitivity. These issues often do not appear on MRI or ultrasound but can still create significant pain.
Why does my lower back hurt when sitting for long periods?
Lower back pain hurting when sitting is commonly linked to prolonged spinal loading, weak core support, and reduced hip mobility. Over time, this creates tissue irritation rather than structural injury.
Why does my lower back hurt when standing or walking?
Lower back pain hurting when standing is often related to poor load distribution through the spine, weak glutes, or joint stiffness. A detailed movement assessment helps identify the exact cause.
Why does my lower back hurt when sleeping?
Lower back pain hurting when sleeping may be caused by sustained muscle tension, disc irritation, or poor sleep posture. Night pain often signals unresolved mechanical stress rather than damage.
Can acupuncture help lower back pain?
Yes. Back pain acupuncture in Mississauga can reduce muscle guarding, improve circulation, and calm irritated nerves. When combined with movement-based treatment, it supports long-term recovery.
What if my back pain started after a fall?
Back pain from falling down may involve protective muscle tightness or joint irritation even if scans show no fracture. Early assessment helps prevent the pain from becoming chronic.
When should I seek professional treatment for lower back pain?
You should seek care if pain persists longer than a few weeks, interferes with sleep, worsens with sitting or standing, or continues despite imaging showing “nothing wrong.”
