One of our patients put it plainly: “I haven't been able to reach my wallet in my back pocket for months. Forget the pain — my arm simply doesn't go there.” That is frozen shoulder in one sentence: on top of the pain, a wall of lost movement that has nothing to do with willpower.
At our clinic in Antalya, frozen shoulder is the most frequently misread shoulder problem we see. Most patients arrive convinced they have a tear or arthritis. The trouble is not in the muscle or the tendon — it is in the sleeve that wraps the joint.
What is frozen shoulder, and how do you recognise the symptoms?
The shoulder joint sits inside a loose envelope called the shoulder capsule. In a healthy shoulder that capsule is slack; it unfolds without resistance when you lift your arm overhead or reach behind your back.
In adhesive capsulitis the capsule first becomes inflamed, then thickens and contracts. Adhesions form on its inner surface and the lubricating fluid decreases. A joint space that normally holds 25-30 millilitres of fluid can shrink to 5-10 millilitres in advanced cases.
So the reason your arm will not rise is not muscle weakness. It is a mechanical block. The sleeve has shrunk. This is exactly why the instinct of “if I push harder it will open up” usually backfires in frozen shoulder.
These are the symptoms our patients describe:
- Shoulder pain that creeps in. Usually there is no clear history of a fall or a strain.
- Night pain and being unable to lie on that shoulder. Sleep-breaking pain is the most typical early sign.
- Progressive shoulder stiffness. Restricted shoulder movement that starts alongside the pain and later becomes independent of it.
- Clear loss of shoulder mobility in daily tasks. Combing hair, fastening a belt behind the back, reaching a high shelf, putting on a jacket.
- Neither you nor anyone else can lift the arm. This detail sits at the centre of the diagnosis; we cover it in its own section below.
Three stages: freezing, frozen, thawing
Frozen shoulder is not a fixed picture; it is a process with its own timetable. Correct treatment depends entirely on identifying which stage you are in.
1. Freezing (painful) stage — roughly 2 to 9 months.
Pain dominates. It typically worsens at night, you cannot lie on that shoulder and it wakes you from sleep. Range of motion narrows steadily during this period, although patients usually interpret it as “I can't move it because it hurts.” The capsule is inflamed at this stage.
2. Frozen (stiffness) stage — roughly 4 to 12 months.
Pain clearly recedes, and many patients therefore assume they are recovering. In fact the real restriction surfaces now. Combing your hair, fastening a bra or a belt behind your back, pulling the seat belt across, reaching into a back pocket — all become difficult. Because the pain has settled, the tissue can now tolerate stretching.
3. Thawing stage — roughly 5 to 24 months.
The capsule slowly regains its elasticity and movement returns in stages. A structured exercise programme markedly speeds up that recovery; shoulders left to themselves often keep a permanent deficit, particularly in outward rotation.
Aggressive stretching harms a shoulder in the painful stage. The very same stretch is the treatment itself in the stiff stage. Most mistakes in frozen shoulder come from doing the right exercise in the wrong stage.
The reason is simple: forcing an inflamed capsule increases the inflammation, increases the pain, and the shoulder guards itself even harder — which accelerates the contracture. In the painful stage the goal is not to gain range but to avoid losing the pain-free range you still have.
Who gets it most often?
Frozen shoulder does not strike at random. These are the risk profiles we see in the clinic:
- Ages 40 to 60. It occurs outside this band too, but the typical patient sits inside it.
- More common in women. Female patients clearly outnumber male ones in our caseload.
- Diabetes — the single most important risk factor. Frozen shoulder is several times more common in people with diabetes than in the general population. More than that, in diabetic patients the process lasts longer, is more stubborn, and is more likely to affect both shoulders. Blood sugar control is part of the treatment.
- Thyroid disease. Both underactive and overactive thyroid conditions raise the incidence.
- Prolonged immobility. An arm kept in a sling, a period in a cast after a fracture, a long spell of bed rest — the longer the shoulder stays still, the more the capsule contracts.
- After shoulder surgery, breast surgery or a fracture. Avoiding the arm because of post-operative pain is one of the most common triggers of frozen shoulder.
If you have had frozen shoulder on one side, the risk in the other shoulder is higher. The good news: it rarely returns in the same shoulder.
What separates frozen shoulder from other shoulder pain
This is the most important section of the article, because the distinction changes the treatment from the very first session.
With impingement syndrome or a rotator cuff tear, the patient cannot lift the arm themselves — but when the physiotherapist takes the arm and asks them to relax, the movement is there. Active motion is restricted, passive motion is free. The problem lies in force production and pain.
In frozen shoulder both active and passive motion are restricted. When we lift the arm for you, we still hit a firm wall at a certain point. The movement does not appear even with the patient fully relaxed, because the block is in the capsule, not in the muscle.
The direction lost earliest and most severely is external rotation: keep your elbow tucked against your body and turn your forearm outward. In frozen shoulder this movement disappears early and unmistakably — in impingement it is usually preserved. The typical pattern on examination is: external rotation lost most, then lifting the arm out to the side, with inward rotation least affected.
X-rays are usually normal in frozen shoulder; they are ordered mainly to rule out arthritis and calcific tendinitis. The diagnosis is largely a clinical one. The American Academy of Orthopaedic Surgeons patient guide describes the same three-stage course.
What we do in the clinic
In the first session we measure the shoulder's range of motion with a goniometer and record it. That measurement matters both for staging and for tracking genuine progress — “it feels a bit better” is not enough to base a treatment decision on.
In the painful stage our priority is calming the pain and restoring sleep. Supported movement kept strictly inside the pain-free range, physical therapy modalities aimed at pain control, and teaching the right sleeping position (a thin pillow under the shoulder, the arm supported in front of the body) belong to this period. There is no stretching.
In the stiff stage the real gains come from manual therapy and joint mobilisation. Techniques that glide the head of the upper arm bone within the socket open the contracted parts of the capsule step by step. For the protective tension that builds up in the surrounding muscles we add medical massage to the programme.
We usually schedule sessions 2-3 days a week. But let us be honest: in frozen shoulder the home programme does most of the work. Three sessions a week will not replace exercises done twice a day at home.
Three exercises you can do at home
The three movements below form the core programme we give patients in the stiff stage. If you are still in the painful stage, do only the first one, and do it very gently.
1. Pendulum (Codman) exercise
Stand in front of a table, lean forward and support yourself on it with your good hand. Let the stiff arm hang completely free under gravity. Now move that arm not with your muscles but by gently swaying your trunk: forwards and backwards, side to side, and in circles. 30 seconds in each direction, 3-4 times a day.
2. Wall finger walk
Stand about an arm's length from a wall. Place your fingertips on it at shoulder height and walk them upward like a spider. Hold for 10 seconds at the highest point you can reach, then walk them back down. 10 repetitions, 2-3 times a day. Do not cheat by hitching your shoulder up toward your ear.
3. Towel stretch behind the back
Hold a hand towel diagonally behind your back: the good hand grips the upper end over your shoulder, the stiff hand grips the lower end behind your waist. Pull the towel gently upward with the good hand so the lower arm is drawn up. Hold 15-30 seconds, 5 repetitions, twice a day.
How hard to stretch: the movement should give you a mild pulling sensation, never a sharp pain. Any soreness afterwards should settle within 30 minutes. If it lasts longer you have overdone it — reduce the intensity the next day. Ten to fifteen minutes of heat beforehand makes the tissue more pliable.
Recovery time: an honest expectation
We prefer to be blunt with patients about this from the start, because a false expectation is what makes people abandon treatment halfway.
Frozen shoulder is measured in months, often in years. The whole course typically runs one to three years. The great majority of patients improve substantially and return to normal daily life; some are left with a slight deficit, usually in external rotation, which rarely interferes with everyday tasks.
In patients with diabetes the course is longer and more stubborn. That is a known feature of the condition, not a sign that treatment has failed.
So what does treatment change? It does not magically compress the process into a few weeks. It does shorten the painful phase, prevent the stiffness from deepening, restore daily function far earlier, and reduce the risk of a permanent restriction at the end. After treatment itself, the second most important ingredient in frozen shoulder is patience.
When should you see a clinician?
- Your shoulder pain has lasted more than 2-3 weeks and loss of movement has joined it.
- Night pain wakes you and you cannot lie on that shoulder.
- You cannot lift your arm out to the side or in front, or reach behind your back.
- Movement disappeared suddenly after a fall or a blow — a fracture and a tendon tear must be ruled out first.
- There is redness, swelling or fever around the shoulder (this needs urgent assessment).
The common mistake is to stop using the painful arm altogether. That is not protection; it speeds up the contracture of the capsule and makes frozen shoulder worse.
When the capsule is the limiting factor, hands-on joint mobilisation is the main tool for regaining range, so how manual therapy works makes it clearer what we are aiming at in a frozen shoulder. Shoulder pain does not always come from the shoulder: numbness or tingling spreading into the arm points to the neck instead, a distinction we cover in neck pain and posture.
If your shoulder has started to lose movement, do not delay the assessment. At our centre in Muratpaşa, Antalya, we determine your stage and build the programme that fits it. You can start by booking an appointment.
