Back Pain Physiotherapy Sydney | SWITCH Physiotherapy

Why does my back hurt when I move a certain way?

Most people describe back pain by how bad it is. A physiotherapist is usually more interested in when it happens. The pattern – the specific movement, time of day or position that brings it on – often says more about what is going on than the intensity does.

This guide walks through the most common patterns we see in clinic and what each one tends to point toward. It is not a diagnosis. It is a way of paying better attention to your own back, so that when you do speak to a clinician you can describe it usefully.

Back pain first thing in the morning

Stiffness on waking that eases within about half an hour of moving around is extremely common and usually not sinister. Discs absorb fluid overnight and are slightly taller and stiffer in the morning, which is why bending forward to pull on socks can feel worst before breakfast.

What is worth noting is how long it takes to ease. Morning stiffness that loosens quickly behaves differently from stiffness that lingers for hours, or that wakes you in the second half of the night. If it is the second kind, mention it specifically.

Back pain when you cough, sneeze or strain

A sharp catch when you cough or sneeze happens because those actions spike the pressure inside your abdomen and spine. It is a mechanical provocation, and on its own it is common with ordinary disc irritation.

The detail that matters is where the pain goes. Pain that stays local to the back behaves differently from pain that shoots down a leg when you cough. The second pattern suggests nerve involvement and is worth describing precisely – which leg, how far down, and whether anything is numb.

Back pain when walking or standing still

These two are often confused, and separating them is genuinely useful.

Pain that builds the longer you stand, and eases when you sit or lean forward on a trolley, is a different pattern from pain that comes on after a set distance of walking. Both are common, both are treatable, and they usually respond to quite different exercise approaches. If you can tell your physio “I am fine for about ten minutes then it builds”, that is far more useful than “it hurts when I walk”.

Back pain when sitting

Sitting loads the lumbar spine in flexion and takes the deep hip and trunk muscles offline. For a lot of desk-based workers, the issue is not the chair itself but the total time in one position without variation.

A practical test: does standing up and walking for two minutes change it? Pain that reliably eases with movement is behaving mechanically, which is generally a good sign and usually responds well to a graded loading program.

Does core strength actually help lower back pain?

Partly, and not in the way it is usually sold.

The evidence does not support the idea that back pain is caused by a weak core that needs bracing. Plenty of people with very strong trunk muscles have back pain, and plenty of people with unremarkable core strength have none. What does hold up is that graded, progressive exercise helps – and that the specific exercise matters less than doing it consistently and building it up over time.

So the honest answer is that core work can be a useful part of a program, but “strengthen your core” on its own is not a treatment plan. What tends to help more is identifying which movements provoke your pain, restoring confidence in those movements, and loading them progressively.

When the pattern matters more than the pain

Two people can both report their back pain as seven out of ten. One has pain that eases with walking and worsens with sitting. The other has pain that worsens with walking and eases when they sit. Same number, different problem, different plan.

This is why a good assessment spends time on questions that can feel tangential. What you were doing when it started, what makes it better, what makes it worse, and what has changed since – those answers shape the treatment far more than the score out of ten.

Patterns that are not just mechanical

Most back pain is mechanical and settles. A small number of presentations need prompt medical assessment rather than a physiotherapy appointment. These include numbness around the saddle region, loss of bladder or bowel control, progressive weakness in a leg, unexplained weight loss, fever, or significant pain following a fall or accident.

We have covered these in more detail in when back pain is serious. If any of those apply to you, contact a doctor or emergency department rather than waiting for a physio appointment.

Frequently asked questions

Is it better to rest or keep moving with back pain?
For most mechanical back pain, staying gently active is better than bed rest. Prolonged rest tends to make deconditioning and fear of movement worse. That does not mean pushing through sharp pain – it means keeping up light, tolerable activity while the irritable phase settles.

Should I use heat or ice for back pain?
Either is reasonable, and the evidence does not strongly favour one. Most people find heat more comfortable for muscular back pain and stiffness. Use whichever genuinely helps you move more comfortably, and treat it as a comfort measure rather than a treatment in itself.

Does my mattress cause back pain?
Rarely the sole cause, though it can influence comfort. A mattress that lets you sleep reasonably well is more important than any particular firmness rating. If your pain is clearly worse in the morning and eases quickly once you are up, sleeping position and surface are worth a conversation, but they are seldom the whole story.

Do I need a scan for back pain?
Usually not. Imaging often shows age-related changes that are present in people without any pain at all, which can be misleading. We have written about when a scan does and does not change the plan in do I need a scan for back pain.

How long should I wait before seeing someone?
If your pain is settling week to week and you are getting back to normal activity, you may not need to. If it has plateaued, is recurring, or is stopping you doing things that matter to you, that is a reasonable point to get it assessed.

If you want it assessed

If the pattern you recognise here has been hanging around, an assessment can tell you which of these it is and what to do about it. You can read more about how we approach it on our back pain physiotherapy page, or book at your nearest SWITCH clinic. No referral needed.
