How Long Does Frozen Shoulder Last?

Your shoulder has ached for months, you can’t lift your arm past a certain point, and you’re wondering when it will end. The most common question is: how long does it last? The honest answer calls for patience — but understanding how the process unfolds eases the uncertainty and helps you take the right step at the right time.

What is frozen shoulder?

Frozen shoulder is a condition in which the shoulder joint becomes progressively stiff and painful, and movement becomes markedly restricted. That is where the name comes from: the shoulder struggles to move in certain directions, as if it has “frozen”. It is most common between the ages of 40 and 65, and more frequent in women.

Why frozen shoulder develops is, in truth, not fully known; scientific studies do not give a clear answer either. That said, the most understandable trigger is the shoulder being kept still for a period — not using the arm for a long time after an injury, a fracture or surgery, for example, can set the picture off. Beyond this, certain conditions such as diabetes and thyroid disease are known to be seen more often alongside frozen shoulder; but exactly how they affect the picture is not clear.

The three stages of frozen shoulder

Frozen shoulder typically progresses through three stages, and each has a feel of its own.

The painful (freezing) stage: Pain is at the forefront and often becomes more noticeable at night — lying on that arm gets difficult. Movement slowly begins to tighten. The movement that suffers most in this stage is rotating the arm outwards — reaching behind you, or turning the arm as if opening a door handle. The reason is that the lining that wraps the shoulder joint (the capsule) thickens and tightens, and this limits the outward-turning direction in particular.

The frozen stage: Pain usually eases in this stage, but stiffness is at its most pronounced. The arm can no longer move comfortably in many directions; everyday tasks (combing your hair, reaching for something behind you, getting dressed) become difficult.

The thawing stage: Movement gradually returns. This stage progresses slowly, but it is the road towards recovery; over time the shoulder approaches its former function.

So, how long does it last?

Frozen shoulder is a condition that calls for patience. Its stages are measured in months: the painful stage usually lasts a few months, the frozen stage most often 4 to 12 months, and the thawing stage can take longer still. The total course varies from person to person and can sometimes run to a few years. The good news is that most frozen shoulders improve markedly with time — but managing the process well affects both the pain and the time it takes.

How does physiotherapy affect the process?

Physiotherapy’s most important contribution in frozen shoulder is doing the right thing at the right stage — because each stage calls for a different approach. In the early, pain-dominant stage the aim is to manage pain and preserve movement gently; forceful stretching that pushes past the limits of pain can make things worse at this point. In the stage where stiffness takes over, manual therapy techniques directed at restoring joint movement come in, together with movement and stretching work that progresses step by step. The aim is not to force the process, but to do what suits the shoulder at each stage — reducing pain and supporting the return of movement. This is why what matters in frozen shoulder is not “the same exercise for everyone”, but a plan adjusted to the stage and the person.

When should you have an assessment?

If your shoulder pain and stiffness have not eased for several weeks, are disturbing your sleep, or you are finding it increasingly hard to lift your arm, a physiotherapy assessment clarifies which stage you are in and how to proceed. The right timing makes the process easier. Physiotherapy approaches for this region are also covered on the Shoulder Problems page.
