How long does frozen shoulder actually take to get better?

Almost everyone who comes to us with a frozen shoulder has been told it will take "a few months". It usually does not. Being told the real number up front is more useful than being told a comfortable one, so here it is.

The three stages

Freezing (roughly 2 to 9 months). Pain comes first and stiffness follows. This is the stage that wakes you at night and makes you dread reaching behind you for a seatbelt. Movement is being lost, but pain is the dominant problem.

Frozen (roughly 4 to 12 months). The pain settles considerably. The stiffness does not. This is the stage where people wrongly assume they are getting better because it hurts less, and stop doing anything about it.

Thawing (roughly 5 to 24 months). Movement returns slowly. Not always completely — how much you get back depends a lot on what happened during the first two stages.

Add those up and the honest range from first twinge to a shoulder that behaves normally is 18 to 30 months. Some people are quicker. A good number are slower.

What actually changes the outcome

The stage you are in decides the treatment, and getting that wrong is the most common mistake we see.

In the freezing stage, forcing range is counterproductive. The capsule is inflamed and stretching into sharp pain provokes more of the same guarding that is causing the problem. Work here is about calming things down: pain relief, gentle movement inside a comfortable range, sleeping positions that stop the shoulder being loaded all night, and often a discussion with your doctor about a corticosteroid injection.

In the frozen stage, the inflammation has quietened and the restriction is mechanical. This is when hands-on mobilisation and progressive stretching earn their keep, and when doing nothing costs you the most.

In the thawing stage the job is strength. A shoulder that has been guarded for a year has lost muscle, and returning range without returning strength is how people end up with a second problem.

The diabetes link

If you have diabetes, your risk of frozen shoulder is roughly double, and the whole course tends to run longer. It is worth knowing early, because it changes what a realistic target looks like and it makes blood sugar control part of the treatment conversation rather than a side note.

When it is not frozen shoulder

Frozen shoulder restricts movement in every direction, and it restricts it whether you move the arm yourself or someone else moves it for you. If your shoulder is weak but someone else can lift it through a full range, that points towards the rotator cuff instead. If pain radiates below the elbow, or comes with pins and needles in the hand, the neck is a candidate. These are different problems with different treatments, which is the reason an assessment comes before a treatment plan.

What to do now

If your shoulder has been stiffening for more than a few weeks and night pain is part of it, get it assessed rather than waiting to see. Not because physiotherapy makes frozen shoulder disappear — it does not — but because the stage you are in dictates what helps, the stages change, and the cost of treating the wrong stage is measured in months.
