If your lower back keeps flaring up, you’re definitely not alone. It’s one of the most common things we see in the clinic. Often it seems to come out of nowhere—after a bit of gardening, carrying the groceries, a long drive, or even just waking up feeling a bit tight.
The frustrating part is that it settles down, you start feeling good again, and then a few weeks or months later it’s back.
The good news? Recurring back pain is rarely a sign that your back is damaged, worn out, or falling apart. Modern pain science has shown that ongoing back pain is usually influenced by a mix of physical, lifestyle, and psychological factors—not just what’s happening in the tissues themselves.
Why does it keep coming back?
One of the biggest myths about back pain is that every flare-up means you’ve injured something again.
For most people, recurring back pain is more about a sensitive back and a sensitive nervous system than ongoing damage.
Think about getting a bit too much sun at the beach. Once your skin is sunburnt, even a light touch can feel uncomfortable. The tissues aren’t necessarily being damaged further, but the area is more sensitive.
Your back can behave in a similar way. When the system becomes sensitised, movements that are normally safe can start to feel painful.
Pain is always real, but it doesn’t always mean harm.
Common reasons your back keeps flaring up
1. Protecting and guarding the back too much
After a painful episode, it’s completely normal to start moving differently.
Many people brace their core constantly, avoid bending, or move like they’re trying not to spill a cup of coffee balanced on their head.
While this can feel protective in the short term, over time it can actually increase sensitivity and make normal movement feel more threatening.
Learning to move more naturally and confidently is often a really important part of recovery.
2. A sensitive nervous system
Pain isn’t just about muscles, joints, discs, or bones.
Your brain and nervous system play a huge role in how pain is experienced.
Things like:
- Poor sleep
- Stress
- Work pressure
- Anxiety
Previous experiences with pain can all turn the body’s alarm system up a notch. When that alarm system becomes overprotective, everyday movements can trigger pain even when the back itself is healthy and strong.
3. Fear of movement
After a flare-up, it’s common to become cautious around bending, lifting, twisting, or exercise.
The problem is that avoiding movement often leads to reduced confidence, reduced fitness, and increased sensitivity.
The back becomes less adaptable because it’s no longer being exposed to the normal loads and movements it was designed to handle.
4. Lifestyle stress and load
Physical load matters, but life load matters too.
A busy week at work, poor sleep, family stress, illness, reduced exercise, or simply feeling run down can all contribute to a flare-up.
Often it’s not one thing that causes the pain to return—it’s a combination of factors stacking up at the same time.
Why resting it usually doesn’t fix it
Taking things easy for a day or two can help settle an acute flare-up.
But prolonged rest often leads to:
- More stiffness
- Reduced fitness and strength
- Increased sensitivity
- Lower confidence in movement
- Greater fear of re-injury
Before long, the back can start to feel fragile—even though it isn’t.
What actually helps
Most people do best with a combination of:
1. Understanding that the back is strong
One of the most powerful shifts people make is realising that the spine is a robust structure.
It’s designed to bend, lift, twist, carry, paddle, surf, run, and move.
Pain does not automatically mean damage.
2. Returning to normal movement
Rather than avoiding bending or lifting forever, the goal is to gradually rebuild confidence in those movements.
The body adapts best when it’s exposed to movement in a safe, progressive way.
A little bit, often, tends to work better than doing nothing and then trying to do everything at once.
3. Building physical capacity
Strong bodies tend to be more resilient bodies.
Walking, swimming, surfing, strength training, Pilates, gym work, and general activity can all help improve your ability to tolerate load.
The best exercise is usually the one you actually enjoy enough to keep doing.
4. Looking at the bigger picture
Sleep, stress, recovery, work demands, general health, and lifestyle habits all influence pain.
Sometimes the biggest improvements happen when we stop focusing solely on the back and start looking at the whole person.
When to get it checked
It’s worth seeing a physio if:
- It keeps coming back every few weeks or months
- You’re starting to avoid activities you used to enjoy
- You’re worried about damaging your back
- Flare-ups are becoming more frequent
- You’re losing confidence in movement
The bottom line
Recurring lower back pain is rarely a sign that your back is damaged or fragile.
Modern evidence suggests that recovery is often about reducing fear, improving confidence, building capacity, and understanding that pain is influenced by much more than tissue injury alone.
With the right guidance, most people can get back to surfing, gardening, working, exercising, chasing the kids around, and enjoying life without constantly worrying about their back.
And ideally, spend more time checking the surf report than thinking about pain.
