The True Cause of Pain & Injury: A Physio's Guide to Finding Root Causes
Key insights: 60-second read
- Pain has a trigger and a cause – What triggered your pain (e.g., bending over) is often not the cause. The cause is hidden dysfunction that set you up for injury.
- Normal processes don't cause pain – Aging, movement, and repetition expose pre-existing dysfunction, they don't create it from scratch.
- Look above and below the pain – The site of pain is often compensating for dysfunction elsewhere (e.g., knee pain may come from hips or ankles).
- Five principles to find the root cause – 1) Nothing hurts until it hurts, 2) Look above & below, 3) Identify weak links, 4) Find hidden restrictions, 5) Assess movement patterns.
Once injured, it's obviously important to work hard on your rehabilitation and recovery. But have you ever stopped to wonder WHY you became injured in the first place?
Understanding the difference between what triggered your pain and what actually caused it could be the key to lasting recovery.
Why did your back become sore doing something mundane? Why is it your right knee and not your left? Why did you wake up with a stiff neck when you didn't have one before bed?
By asking these simple questions, you can uncover the hidden dysfunction that sets your tissue up to fail. More importantly, this understanding provides the context needed for genuine, long-term resolution.

1. What Is "Normal" When It Comes to Pain and Injury?
Before identifying dysfunction, we need to understand what normal human function looks like. Many things we blame for pain are actually natural processes:
- Aging - a natural process that shouldn't automatically cause pain
- Movement and use - essential for health, not inherently harmful
- Repetitive activities - necessary for skill development and strength
- Growing - a normal biological process
- Being barefoot - our feet are designed for this
- Being pain-free - this should be our default state
The Key Insight
These natural processes don't cause pain - they expose pre-existing dysfunction. When your body is functioning optimally, these normal activities shouldn't lead to injury.
Aging: Time Exposing Dysfunction
While peak function naturally declines with age, pain shouldn't be an inevitable consequence. Consider this: if you develop one-sided hip, knee, or shoulder pain labelled "age-related," why isn't the other side (the same age) equally affected?
Time doesn't create pain - it reveals the weaknesses in your system.
Movement: The Scapegoat for Hidden Issues
We often hear about injuries from "moving the wrong way" or "overuse." But movement is vital for human function - there are no inherently "bad" movements, only movements that expose underlying dysfunction.
In a well-functioning body, repetition should lead to adaptation and strength, not injury.
2. Principle 1: Nothing Hurts Until It Hurts
The moment of injury isn't necessarily the start of the problem - it's when hidden dysfunction finally manifests as pain. What you were doing at that moment may have been the trigger, not the cause.
This principle works both ways: just because your pain has subsided doesn't mean full function has returned. Many people re-injure themselves because they addressed the pain but not the underlying cause.
3. Principle 2: Look Above & Below Your Pain
Your body is a kinetic chain - everything is connected. The site of pain is often compensating for dysfunction elsewhere:
- Knee pain? Check your ankles and hips
- Back pain? Assess your thoracic spine and hips
- Shoulder pain? Evaluate your neck, upper back, and shoulder blades
Your L5/S1 disc might have bulged not because of how you moved, but because of how you were moving in a body with significant hip dysfunction directly below the area.
4. Principle 3: Identify Weak Links
Muscle weakness creates vulnerability throughout the kinetic chain:
- Weak hips alter leg mechanics, leaving knees vulnerable
- Unstable shoulder blades affect all shoulder function
- A weak core forces other muscles to compensate during movement
Recurring hamstring injuries during sprinting might not be about sprinting itself, but about hamstrings compensating for core dysfunction.
5. Principle 4: Find Hidden Restrictions
Joint and tissue restrictions force compensatory movements that overload other areas:
- Restricted hips force your back to move differently
- A stiff ankle alters knee and hip mechanics
- A tight upper back increases strain on the neck and shoulders
Restrictions can be subtle - your body will naturally move around them, making them harder to detect without specific assessment.
6. Principle 5: Assess Movement Patterns & Positioning
Sometimes the issue isn't weakness or restriction, but how you're using your body:
The anatomical position represents our body's ideal alignment. Consider:
- How close is your sitting posture to this ideal position?
- Are you consistently putting tissues in suboptimal positions throughout your day?
- Do you understand proper movement mechanics for your activities?
You might have full mobility and strength, but without proper movement patterns, you could be loading tissues in unsustainable ways.
Putting It All Together: Your Path to Lasting Recovery
Pain and injury are complex, with multiple potential contributing factors beyond the musculoskeletal system. Sleep quality, nutrition, hydration, and stress levels all play crucial roles in tissue health and pain perception.
However, when a specific body part becomes painful at a specific time, there's always a reason. Your body doesn't betray you randomly - there are identifiable mechanical reasons why one area fails when others don't.
Remember: Being pain-free is normal. If you're experiencing pain, something has disrupted your body's natural state of comfort and function. The goal isn't just to eliminate pain, but to restore the conditions that allow your body to thrive naturally.

Frequently Asked Questions
What's the difference between a pain trigger and the root cause?
The trigger is what happened at the moment pain started (e.g., bending over). The root cause is the hidden dysfunction that made you vulnerable - like hip restrictions or weak glutes - that set you up for injury. Treating the trigger alone leads to recurrence.
Why do I have pain on only one side of my body?
This is a key clue that pain isn't simply "age-related." If aging were the cause, both sides (the same age) would be equally affected. One-sided pain suggests asymmetrical dysfunction - like a weak hip, restricted joint, or movement pattern imbalance on that side.
How do I find the root cause of my pain?
Use the five principles: 1) Nothing hurts until it hurts (the trigger isn't the cause), 2) Look above and below the pain site, 3) Identify weak links, 4) Find hidden joint restrictions, and 5) Assess your movement patterns and daily postures. A physio can help with specific assessment.
Can movement really be bad for me?
No. There are no inherently "bad" movements. In a well-functioning body, movement and repetition should lead to adaptation and strength, not injury. Pain during movement usually exposes pre-existing dysfunction that needs to be addressed.
One profound insight from this post
"Nothing hurts until it hurts. The moment of injury isn't the start of the problem - it's when hidden dysfunction finally takes its toll. Treat the cause, not just the trigger."
Living With Persistent Pain?
If your pain has lasted longer than expected, feels disproportionate to injury, or hasn't responded to standard treatment, you may benefit from a broader approach. Learn more about our physiotherapy services in Port Macquarie.
