Frozen shoulder can creep up slowly. It can start as a nagging ache first, then a shoulder that won’t reach overhead, behind your back or into a jacket sleeve without a fight. It’s frustrating, it can wreck your sleep, and it’s often a slow condition to settle on its own. Frozen shoulder is estimated to affect around 2–5% of the general population, most commonly people in their 40s to 60s. There is a 6–17% risk of frozen shoulder developing in the other shoulder within 5 years, and recurrence in the same shoulder is rare.
Frozen shoulder, medically known as adhesive capsulitis, is a condition where the capsule surrounding the shoulder joint becomes inflamed, thickened and tight. As the capsule tightens, the joint has less room to move, so pain and stiffness build over time. A key feature is that movement is limited both when you lift your arm yourself and when someone else tries to move it for you, especially when rotating the arm outwards.
Timeframes vary a lot from person to person. Overall, most people recover over 1 to 3 years, and many see meaningful improvement sooner with good management.
In many people there’s no clear cause, but some factors are linked with a higher risk:
Our approach at Bend + Mend
Most people recover within 1 to 3 years. It typically moves through a painful stage, a stiff stage and a recovery stage. With the right treatment, pain can often be eased and function improved along the way.
For most people it does improve over time, but recovery can be slow and some stiffness may linger. Physiotherapy helps manage pain, protect your movement and support a smoother recovery.
Complete rest can allow more stiffness, while aggressive stretching can flare your pain. Gentle, regular movement within a comfortable range is the usual guide, and we’ll show you what’s right for your stage.
In frozen shoulder, movement is limited even when someone else moves your arm, especially rotating outwards. In rotator cuff problems, the joint usually still moves passively but certain actions are painful or weak. A physio assessment can tell the difference.
