Understanding Neck Pain: Why Your Neck Hurts
If you've spent the day hunched over a laptop, or you woke up unable to turn your head without wincing, you're dealing with one of the most common complaints I see in clinic. Neck pain affects a huge number of people at any given time, and, much like low back pain, it's rarely a sign that something is seriously wrong, even when it feels intense.
What is neck pain, really?
Most neck pain that walks through a physio's door falls under the umbrella of "mechanical" or non-specific neck pain: pain related to how the joints, muscles and surrounding tissues of the neck are moving and coping with load, rather than a single structural injury.
Clinical guidelines generally group neck pain presentations into a few patterns:
neck pain with restricted movement,
neck pain with an associated headache,
neck pain that radiates down the arm (often related to a nerve root), and
neck pain following a whiplash-type injury.
Globally, neck pain is one of the most common musculoskeletal complaints and a leading cause of disability, affecting people across almost every age group, though it tends to affect women somewhat more than men.
What does it feel like?
Neck pain shows up in a few recognisable ways:
Stiffness or a dull ache through the back or side of the neck, often worse with certain positions
Sharp pain or a "catch" with turning your head
Pain spreading into the shoulder, upper back, or down the arm
Headaches starting from the base of the skull or neck
Muscle tightness or spasm, particularly after long periods at a desk or in the car
Like most musculoskeletal pain, it tends to fluctuate, better some days, flared on others, often tied to how much load or how many static hours you've put through your neck.
Why does it happen?
Neck pain usually develops from a mix of contributing factors rather than one single cause. Common contributors include:
Prolonged static postures — long stretches at a screen, driving, or reading without breaks
A sudden increase in unaccustomed activity or load
Sleep quality and sleeping position
Stress and muscle tension, which commonly settles in the neck and shoulders
Previous neck injury, including whiplash
General deconditioning of the neck and shoulder muscles
Occupational demands, particularly repetitive or sustained positions
What about phones and "text neck"?
This one comes up a lot, so let's address it directly. There's a lot of research looking at smartphone use and neck pain, and a recent systematic review and meta-analysis did find an association between heavier smartphone use and reporting neck pain.
However, it's worth being clear about what that actually means: the underlying studies were mostly cross-sectional and retrospective, meaning they can show a relationship exists but can't confirm that phone posture is the direct cause of anyone's individual pain. Plenty of people spend hours on their phones without ever developing neck pain, and plenty of long-term neck pain has little to do with phone use at all.
So, moderating extended, unbroken phone or screen time is a reasonable, low-cost thing to do, but it isn't accurate to say your phone is definitely "the cause" of your neck pain, and constantly policing your posture usually isn't the answer either.
Common misconceptions
"I must have poor posture" — posture plays a role for some people, but it's rarely the sole cause, and there's no single "correct" posture that prevents neck pain for everyone.
"Something is out of place and needs to be put back" — this isn't how the neck works structurally; joints don't typically "slip out," even though it can feel that way.
"I need a scan to know what's wrong" — imaging is usually unnecessary for straightforward mechanical neck pain and rarely changes the treatment plan.
"I should keep my neck completely still until it heals" — prolonged avoidance of movement tends to increase stiffness rather than help.
Is it serious?
The overwhelming majority of neck pain is not dangerous and improves with appropriate management.
That said, a small number of symptoms warrant prompt medical assessment, because they can (rarely) indicate something more serious:
Progressive weakness, numbness, or clumsiness in both hands, or difficulty with fine motor tasks like buttoning a shirt
Changes to your walking pattern or balance
Significant, unremitting night pain, or pain alongside unexplained weight loss
Neck pain following major trauma, such as a car accident or a fall from height
Severe headache with neck pain accompanied by visual disturbance, slurred speech, dizziness, or facial numbness
A history of cancer, or fever alongside new neck pain
These situations are uncommon, but if you notice any of them, seek prompt medical assessment rather than starting with self-management.
When should you see a physiotherapist?
You don't need to wait for things to become unbearable or chronic. It's worth getting assessed if your neck pain is limiting your work, sleep, or day-to-day activities, if it's not settling with a few days of sensible self-management, or if you're getting recurrent episodes and want to understand what's driving them.
What happens during a physiotherapy assessment?
A thorough neck assessment typically includes:
A detailed history — how symptoms started, what makes them better or worse, and how they're affecting your life
Screening questions to rule out anything requiring more urgent medical attention, including checking for any risk factors before certain hands-on techniques are used
An assessment of your neck movement, strength, and how symptoms respond to different positions and loads
A look at broader contributing factors — workstation setup, sleep, stress, activity levels
A clear explanation of what's likely going on and what a sensible plan looks like
Is imaging usually required?
For most non-specific neck pain, no. As with low back pain, imaging findings like disc degeneration are extremely common in people with no neck pain at all, particularly as we age, so a scan often doesn't add useful information unless red flag symptoms are present or your presentation isn't following an expected recovery pattern.
What can you expect from here?
Most episodes of neck pain improve meaningfully within a matter of weeks with appropriate active management, though, like low back pain, recurrence over time is common.
Understanding what's genuinely driving your symptoms (and ruling out what isn't) is usually the first step toward feeling more confident moving your neck again.
In the next article, we'll cover exactly what to do about it, including whether you need to fix your posture, what exercises actually help, and how to get back to your normal activities.

If your neck pain isn't settling, or you're not sure what's driving it, a physiotherapy assessment can help identify what's contributing to your symptoms and build a clear plan to get you moving comfortably again.
