Shoulder pain is incredibly common, but that doesn’t mean it’s always straightforward.

While many people assume it’s a simple strain or injury, the reality is often more complex.

As highlighted in a recent feature in the Daily Mail, shoulder pain can come from a range of causes, including issues that aren’t even in the shoulder itself.

At The Physio Box Clinic, one of the most common things we see is patients being treated for the wrong problem.

“I often see patients treated for months for shoulder pain, when the real issue is coming from the neck — and hasn’t been properly assessed.”
– Giuseppe Salustri, The Physio Box Clinic, featured in the Daily Mail

Why shoulder pain is often misdiagnosed

The shoulder is closely connected to the neck, upper back, and nervous system.

That means:

  • Pain can be referred from elsewhere (especially the neck)
  • Symptoms can overlap between different conditions
  • The true cause isn’t always obvious without proper assessment

This is where many people go wrong – they treat the symptom (shoulder pain), not the source.

When shoulder pain is coming from the neck

One of the most commonly missed causes of shoulder pain is referred pain from the neck.

This happens when a nerve in the neck becomes irritated or compressed.

Instead of feeling pain in the neck, you may experience:

  • Pain in the shoulder or shoulder blade
  • Tingling or numbness down the arm
  • A dull ache that doesn’t change much with shoulder movement

A simple way to spot the difference:

  • If moving your shoulder makes the pain worse → likely a shoulder issue
  • If movement doesn’t change the pain much → it may be coming from the neck

This is why we always assess the neck as part of any shoulder pain diagnosis.

The most common shoulder injury: rotator cuff problems

Once neck-related causes are ruled out, the most common issue we see is rotator cuff injury.

This involves irritation or damage to the tendons that stabilise the shoulder.

Typical signs include:

  • Pain when lifting your arm (especially overhead)
  • Weakness or reduced control
  • Pain when reaching, pushing, or pulling

These injuries are often linked to:

  • Repetitive movements (gym, sports, manual work)
  • Poor shoulder strength or control
  • Age-related changes in tendon health

Why strengthening alone isn’t enough

A common mistake is focusing purely on strength.

While strengthening is important, it’s only part of the picture.

One area that’s often overlooked is muscle activation timing—how quickly and effectively your muscles respond.

If the rotator cuff muscles don’t activate at the right time:

  • The shoulder becomes less stable
  • Other tissues take on too much load
  • Pain and injury are more likely to persist

This is why rehab needs to include:

  • Strength
  • Control
  • Coordination

—not just basic exercises.

Frozen shoulder: when movement becomes restricted

Another common cause of shoulder pain is frozen shoulder.

This condition:

  • Develops gradually
  • Causes increasing stiffness and pain
  • Can severely limit movement

Many people describe it as:

  • A “block” when trying to lift the arm
  • Difficulty with everyday tasks (e.g. dressing, reaching behind)

It’s particularly common in:

  • People aged 40–60
  • Women (especially around menopause)

Treatment often requires a broader, staged approach, rather than just exercises alone.

Why guidance matters in recovery

One of the biggest challenges with shoulder pain isn’t just the injury—it’s knowing how to manage it.

Many people are:

  • Given exercises
  • Told to “rest” or “keep moving”
  • Left unsure how to progress safely

This often leads to:

  • Doing too little (slowing recovery)
  • Doing too much too soon (making it worse)

At The Physio Box, we focus on giving clear, structured guidance so you know:

  • What to do
  • When to progress
  • How to rebuild strength safely

A smarter approach to shoulder pain

The key takeaway from the Daily Mail feature is highlighted by Giuseppe Salustri:

Not all shoulder pain comes from the shoulder—and getting the diagnosis right is everything.

With the right assessment and treatment plan, most shoulder conditions can improve significantly without invasive treatment.

Shoulder Pain FAQs

Can shoulder pain come from the neck?
Yes—nerve irritation in the neck can cause referred pain in the shoulder and arm.

What is the most common cause of shoulder pain?
Rotator cuff injuries are the most common, especially with age or repetitive movement.

How do I know if my shoulder pain is serious?
If it’s persistent, worsening, or not improving with rest, it’s worth getting assessed.

Can shoulder pain go away on its own?
Some minor injuries can improve, but many require targeted rehabilitation.
