How long does frozen shoulder last?

By the Calm Joints physio team · Updated October 9, 2026 · 8 min read

Frozen shoulder, also called adhesive capsulitis, usually lasts many months and often one to three years. Pain and stiffness tend to ease, but recovery is not always complete, and waiting it out is not the only option. Early pain control, a simple home exercise plan, and a physio who can pace the load often make the months easier.

How long does frozen shoulder last?

Most people are looking at a long arc, not a weekend strain. The American Academy of Orthopaedic Surgeons describes three overlapping stages. The freezing stage, when pain rises and motion drops, often lasts 6 weeks to 9 months. The frozen stage, when pain may settle but stiffness stays, often lasts 4 to 6 months. The thawing stage, when motion slowly returns, often lasts 6 months to 2 years. Full recovery, or close to it, can take up to 3 years.^[1]

The NHS puts the same idea in plainer words: a frozen shoulder is painful and stiff for months, sometimes years, and the pain and stiffness usually go away eventually.^[2]

A long Finnish follow-up found the illness itself averaged about 15 months in people who had no treatment (range 4 to 36 months) and about 20 months in people treated without surgery (range 6 to 60 months). Years later, motion had returned to the other shoulder's level in about 9 in 10 people. Not everyone was pain-free. About half of the untreated group still had some pain at rest, at night, or with effort.^[3]

So the honest answer is: plan for a year or more, expect improvement, and do not assume the shoulder will reset itself if you ignore it.

What are the stages, really?

Clinics still use the freezing, frozen, and thawing labels because they match what people feel. Night pain that wrecks sleep. Then a shoulder that will not reach a seatbelt, a coat sleeve, or the back of the head. Then a slow return of reach.

Treat the stages as a map, not a timetable. A 2017 systematic review found low-quality evidence that no treatment brought some, but not complete, improvement in motion after 1 to 4 years. It did not find evidence that people reliably march through three phases to full recovery with no care. In trials with longer follow-up, most of the improvement showed up early, not late.^[4]

That matters if someone has told you to "just wait for the thaw." Some motion often returns. Lingering stiffness and night ache are common enough that a plan is worth having.

Who tends to have a longer course?

Frozen shoulder is most common in the 40s to 60s, and more often in women. It can follow a period of not moving the arm, after an injury or surgery, or it can start with no clear cause. Diabetes raises the chance of getting it, though the reason is not settled.^[1]^[2]

In the UK FROST trial of 503 adults with primary frozen shoulder, the average age was 54, about 63 percent were women, and about 30 percent had diabetes.^[5] Diabetes does not mean you are stuck. It does mean a slower course is possible, and regular diabetes care still matters.

The other shoulder is involved later in some people. Do not assume a stiff left shoulder dooms the right one. Mention it at a visit so the plan covers both sides if needed.

What the research says

A 2020 meta-analysis of 65 studies and 4,097 people compared treatments. A steroid injection into the joint was linked with better short-term pain and function than no treatment or physiotherapy alone, and that edge seemed to last up to about 6 months. Adding a simple home exercise program, and in some comparisons physiotherapy, was linked with extra benefit into the mid-term. The authors suggest offering an injection early, in the first year, and pairing it with home exercise.^[6]

A Cochrane review is more cautious on hands-on care. A combination of manual therapy and exercise probably improved pain and function less than a steroid injection in the first seven weeks. By 6 and 12 months, the differences were not clinically important.^[7]

UK FROST compared early structured physiotherapy (with a steroid injection), manipulation under anaesthesia, and arthroscopic capsular release. At 12 months, none of the three was clinically superior on the Oxford Shoulder Score. Capsular release had more serious adverse events. Early structured physiotherapy was the accessible option. In that trial's cost analysis, manipulation under anaesthesia had the highest probability of being cost-effective.^[5]

Read those together. An injection can take the edge off earlier. Exercise and physiotherapy are the work that keeps the shoulder moving while it settles. Surgery is not the default, and it is not clearly better at a year for primary frozen shoulder in that large trial.

Virtual physio can carry a lot of this. A 2017 systematic review and meta-analysis found real-time telerehabilitation effective and comparable to usual care for pain and function across musculoskeletal conditions.^[8] A later review still supports telerehabilitation when a full in-person program is not practical, with effects that vary by condition.^[9] For frozen shoulder, the visit is mostly assessment, pacing, and a home program. That travels well on a screen.

In Canada, community physiotherapy is usually paid through extended health benefits or privately. OHIP does not cover routine community physio for most adults in Ontario. Virtual visits are available across provinces. Check your plan before you assume it is or is not covered.

These are gentle options for a shoulder that is stiff, not a freshly injured or hot, swollen joint. Stop if pain jumps, the arm feels unstable, or symptoms are worse the next morning. Sharp pain is a stop sign. A mild stretch is acceptable.

1. Pendulum hang

Stand beside a counter. Support the well arm. Lean forward and let the sore arm hang. Make small circles, about the size of a plate, for 30 to 60 seconds. Rest. Repeat 2 or 3 times, once or twice a day. The arm should feel loose, not yanked.

Stop if the shoulder catches, or if pain lasts more than a few minutes after you stand up.

2. Table slide

Sit at a table with a towel under the hand of the sore arm. Slide the hand forward, as if polishing the table, until you feel a modest stretch in the shoulder or armpit. Hold 5 slow breaths. Slide back. Do 8 to 10 slides, once a day.

Stop if you have to hike the shoulder to the ear to get the hand forward, or if pain spikes above a mild stretch.

3. Wall walk, only if the freezing pain has eased

Stand facing a wall, about a hand's length away. Walk the fingers up the wall to the first point of stiffness. Hold 5 breaths. Walk back down. Do 5 to 8 walks. Skip this on days when night pain is raging. Forcing elevation early often backfires.

Stop if the pain is sharp, or if you cannot lower the arm without help.

4. Heat before, easy movement after

The NHS suggests a heat pack or hot water bottle, wrapped in a towel, for up to 20 minutes, and says keeping the shoulder still tends to make pain worse.^[2] Use heat, then do the pendulum or table slide. Do not invent a hard gym program. Heavy overhead pressing and sudden jerks are a poor match for a frozen shoulder.

A winter coat is a useful test in Canada. If getting the arm into a sleeve takes a full minute and leaves you swearing, that is a cue to book, not a cue to force the sleeve on.

Physio tip: In the freezing stage, chase a calm shoulder tomorrow, not a bigger stretch today. Warm the joint with a wrapped heat pack, move only to a gentle stretch, and stop while it is still tolerable. If the shoulder is clearly worse that night or the next morning, the last session was too much.

When to see a physio

Book if the shoulder has been painful and stiff for more than a few weeks, if sleep is broken, or if you cannot reach a seatbelt, wash your hair, or dress without a workaround. A physio can confirm the pattern, set a dose you can keep, and tell you when an injection or a family doctor visit is the better next step.

Get urgent in-person care, and do not wait for a routine physio visit, if you have chest pain with the shoulder pain, fever with a hot swollen shoulder, pain after a fall, sudden weakness or numbness, or unexplained weight loss with new constant night pain. Call 911 for chest pain that feels tight or squeezing, pain spreading into the neck or jaw, or severe trouble breathing.
