7 Causes of Shoulder Pain Most People Overlook

The shoulder is the most mobile joint in the body, which makes it powerful — and vulnerable. When it hurts, people often assume it’s a simple strain. But shoulder pain can stem from several structures, and pinning down the real cause is the key to fixing it.

1. Rotator cuff strains and tears

The rotator cuff is a group of muscles and tendons that stabilise the shoulder. Overuse or injury causes pain with lifting and reaching, weakness and night pain — one of the most common shoulder problems we treat.

2. Impingement

When tendons get pinched during overhead movement, you feel a sharp catch. Strengthening and movement retraining usually resolve it.

3. Frozen shoulder

Adhesive capsulitis causes progressive stiffness and pain that can severely limit movement. Guided physiotherapy helps restore range through each stage.

4. Your neck (referred pain)

Surprisingly, many ‘shoulder’ problems actually originate in the neck. Nerve irritation there can refer pain into the shoulder and arm — which is why a good assessment checks both.

5. Bursitis and tendonitis

Inflammation of the bursa or tendons causes aching and tenderness, often from repetitive activity. Shockwave therapy can help stubborn cases.

6. Poor posture

Rounded shoulders and ‘tech neck’ change how the shoulder moves, gradually leading to pain. Postural work is often part of the solution.

7. Old injuries and post-surgery stiffness

Previous injuries or surgery can leave lasting stiffness and weakness that rehab addresses — helping you regain full, pain-free movement.

The takeaway

Because shoulder pain has so many possible causes, a proper assessment matters. If your shoulder has been bothering you for more than a week, book an assessment and we’ll identify exactly what’s going on and how to fix it.
