How Long Does Frozen Shoulder Last? The Evidence

How long does frozen shoulder last, stage by stage?

Each stage has its own rough length, and adding them up is how most people arrive at a figure of one to two years. OrthoInfo gives the painful freezing stage 6 weeks to 9 months, the stiff frozen stage 4 to 6 months, and the thawing stage 6 months to 2 years for a complete return to normal or close to normal strength and movement. The same page says full recovery may take up to 3 years.

Those ranges are wide for a reason. The freezing stage can be six weeks or it can be most of a year, and nobody can tell you in advance which you have. The three stages explains how to work out where you are, which is more useful than a total, because what you should be doing depends on the stage and not on the month.

Does frozen shoulder always get better on its own?

This is where the usual reassurance goes further than the evidence. The claim that frozen shoulder is self-limiting and resolves completely without treatment was proposed in the 1940s, and Wong and colleagues went looking for the studies behind it. Seven met their criteria. The evidence was low quality, untreated shoulders regained some but not complete range of movement over 1 to 4 years, and most of the improvement they did get came early rather than late (Wong and colleagues, 2017).

Hand and colleagues give the longest view. They assessed 269 shoulders in 223 people with primary frozen shoulder, an average of 4.4 years after symptoms began. Of those people, 59 percent had normal or near normal shoulders and 41 percent reported some ongoing symptoms. Of the symptoms that remained, 94 percent were mild, with pain the commonest complaint, and 6 percent were severe, with pain and loss of function (Hand and colleagues, 2008).

In the same group, 20 percent had symptoms in both shoulders.

Read together, those two studies support a different sentence from the one people are usually given. Most frozen shoulders end up as working shoulders. Not all of them end up as unremarkable ones, and being told two years and then still having a sore shoulder at month 30 is its own kind of setback.

What makes frozen shoulder last longer?

Diabetes is the clearest factor. OrthoInfo says frozen shoulder is far commoner in people with diabetes, and that their shoulders tend to be stiffer and to hold on to the stiffness for longer before any thaw starts. Frozen shoulder and diabetes goes through what that means in practice.

A severe start matters too. In the Hand study, the people with the worst symptoms at the beginning had the worst long-term outcome (Hand and colleagues, 2008). That is an association rather than proof, but it is one reason not to spend the painful months doing nothing and hoping.

The stage of life a shoulder arrives in gets blamed more often than the evidence supports. Frozen shoulder and the menopause goes through what the ages actually show and what they do not.

How hard you stretch can work against you. In a Dutch study of 77 people, those whose treatment was held inside their pain limits came out ahead at two years of those put through intensive passive stretching and manual mobilization (Diercks and Stevens, 2004). It was not a randomized trial, so it cannot settle the matter alone, and the JOSPT guideline separately warns that stretching beyond painful limits may lead to poorer outcomes (Kelley and colleagues, 2013).

Can anything speed it up?

Pain relief can arrive much sooner than movement does, and that is worth having on its own. A meta-analysis pulling together 65 randomized studies with 4,097 participants found that of all the options compared, only a corticosteroid injection into the joint was both statistically and clinically better than the alternatives in the short term for pain and function. Its authors concluded that using it early, in shoulders of less than a year's duration, went with better outcomes, and that it should be given alongside a home exercise program (Challoumas and colleagues, 2020). The JOSPT guideline reaches the same practical place: injection plus mobility and stretching exercises beat exercises alone over the first 4 to 6 weeks (Kelley and colleagues, 2013).

For a shoulder that stays very stiff after months of good care, the UK FROST trial compared early structured physiotherapy with a steroid injection against manipulation under anesthesia and against keyhole surgery to release the capsule, in over 500 adults. None of the three was clearly better than the others at 12 months, and the keyhole release carried more risk. Injections and other treatments sets out what each one involves.

Exercise is not a shortcut, and it is still the thing you do most of. What it buys you is a shoulder that stays as useful as possible through a long wait, and range that comes back a little at a time rather than all at the end. Frozen shoulder exercises by stage sets out the dose, and the frozen shoulder program has the videos.

When to see a physio or doctor

Early is better than late, and most people wait too long. A physio (physical therapist) can confirm it is a capsule problem rather than a tendon, arthritis or referred neck pain, and can set the stretch intensity to the state your shoulder is actually in.

Go back if nothing has changed over two or three months, if sleep is still being wrecked, or if the shoulder starts getting stiffer again after a period of improvement. Shoulder pain at night covers the sleep side. Anything on the list below needs attention sooner, at the timing each line gives.

Warning signs

Get emergency help now

Chest pain or tightness, which may spread to your arm, neck or jaw, or shoulder or arm pain that comes with shortness of breath, sweating or feeling sick. This can be a heart attack. Call emergency services straight away.
The shoulder feels as if it has slipped out of place, looks a different shape or suddenly locks so you cannot move the arm, or the pain is severe after a fall or an injury. Go to an emergency department straight away, without driving yourself, and do not try to put the shoulder back in yourself.
Your arm, hand or fingers turn cold, pale, blue or gray compared with the other side. Call emergency services or go to an emergency department straight away, and do not drive yourself. The blood supply to the arm may be blocked.
You have a fever or feel unwell, or the shoulder is hot, red and swollen. This can be a joint infection. Go to an emergency department straight away.

Get help today

Sudden, very bad shoulder pain, or you suddenly cannot lift or move your arm at all. Get medical help the same day.
The pain started after a fall, a pull or another injury, especially if the arm has been weak since, for example you cannot lift it out to the side or hold it up. This can be a broken bone or a torn tendon. Get medical advice the same day, and say how it happened and that the arm has been weak since, because UK shoulder surgeons advise urgent referral for a rotator cuff tear caused by an injury.
Severe pain in both shoulders that has come on recently. Get medical advice the same day.
You are over 50 and have aching and stiffness in both shoulders, often in the neck or hips too, that is worst in the morning and lasts more than 45 minutes after you get up. This can be an inflammatory condition (polymyalgia rheumatica) rather than frozen shoulder. If you also get a new headache, pain or tenderness at your temples or on your scalp, or jaw pain when you eat or talk, get medical advice the same day, and if your vision changes, call emergency services. Even without those extra signs, see your doctor within a few days about the aching and stiffness.
Pins and needles or numbness in the arm that does not go away, no feeling in part of the arm, or weakness that is getting worse. Get medical advice the same day. For pain spreading down the arm from your neck, ask for an urgent appointment with your doctor. If one side of your face or body suddenly goes numb or weak, or your speech becomes slurred or muddled, call emergency services, even if it goes away.
Pain at night or at rest that is constant, that no rest or change of position eases at all, and that keeps getting worse. If you are being treated for cancer now, contact your cancer team the same day.

Book an appointment

Pain at night or at rest that is constant, that no rest or change of position eases at all, and that keeps getting worse. If you have had cancer, now or in the past, or are losing weight without trying, see your doctor sooner, within a day or two, and mention it. This applies even if the pain is not getting worse.
Night pain is common with this condition, but get checked within a few days if the pain is constant, no rest or change of position eases it at all, and it keeps getting worse.
New shoulder pain and you have had cancer, now or in the past, or you are losing weight without trying. See your doctor within a day or two and mention it.

Common questions

Does frozen shoulder always go away in two years?

Not always, and the two year line is older than the evidence behind it. Wong and colleagues searched for the studies supporting the idea that frozen shoulder runs its course and resolves completely without treatment. They found seven, rated the evidence low quality, and reported that untreated shoulders regained some but not complete range of movement over 1 to 4 years (Wong and colleagues, 2017). Hand and colleagues, following 269 shoulders in 223 people for an average of 4.4 years, found 41 percent of those people with some remaining symptoms, 94 percent of those symptoms mild and 6 percent of them severe enough to affect function (Hand and colleagues, 2008). Most people do end up with a usable shoulder. Completely normal is less certain than the old line suggests.

Will my frozen shoulder ever feel completely normal again?

For most people it gets close. In the Hand study, 59 percent of the people had normal or near normal shoulders at an average of 4.4 years, and the symptoms that remained in the rest were usually mild pain rather than disability (Hand and colleagues, 2008). The movement most often left slightly short is turning the arm outward with the elbow at your side, and plenty of people never notice that in daily life. One finding is worth knowing: the people with the most severe symptoms at the start had the worst long-term outlook, which is an argument for getting the painful phase managed properly rather than waiting it out alone.

Does treatment make frozen shoulder go away faster?

Some of it helps the pain sooner, and that is not the same as shortening the condition. The JOSPT guideline gives its strongest grade to a steroid injection into the joint combined with mobility and stretching exercises, which gave better pain relief and function over the first 4 to 6 weeks than exercises alone (Kelley and colleagues, 2013). A meta-analysis of 65 randomized studies found that a corticosteroid injection into the joint was the only treatment clearly better than the others in the short term for pain and function, and that it worked best used early, within the first year, alongside a home exercise program (Challoumas and colleagues, 2020). Over 6 to 12 months the gap between treatments narrows.

Why is my frozen shoulder taking so long?

Usually because this is how long it takes, not because something has gone wrong. The capsule tightened over months and it loosens over months. Two things do go with a slower course: diabetes, which OrthoInfo links to a stiffer shoulder that takes longer to thaw, and a very painful start. If the shoulder has not changed at all over two or three months of steady work, that is a reason to be reassessed rather than to push harder, because a shoulder that is stiff for another reason will not respond to a frozen shoulder program.
