Frozen Shoulder: The Three Phases and What Helps in Each One
Written by Nicolas Marchant, Registered Physiotherapist. In nearly two decades of practice, frozen shoulder is the condition I most often see people endure for months before anyone explains to them what is actually happening.
Frozen shoulder is unusual among shoulder problems: it typically arrives without an injury, it gets worse before it gets better, and it follows a pattern predictable enough that clinicians describe it in phases. Understanding which phase you are in changes what treatment should look like, and it is the single most useful thing to know about the condition.
The medical term is adhesive capsulitis. The capsule surrounding the shoulder joint becomes inflamed and then thickened and tight, which restricts movement in a characteristic way. It affects both what you can do and what someone else can do with your arm, which is one of the ways it is distinguished from other shoulder conditions.
The three phases, and why they matter
Frozen shoulder moves through three overlapping stages. Timelines vary considerably between people, so treat these as a shape rather than a schedule.
Freezing (the painful phase). Diffuse shoulder pain that is often worse at night, with stiffness building steadily. This phase commonly runs somewhere in the range of 2 to 9 months. The pain is usually the dominant complaint here, and it can be significant enough to disturb sleep.
Frozen (the stiff phase). Pain typically eases, and stiffness becomes the main problem. Reaching behind your back, fastening a seatbelt, or getting a jacket on becomes difficult. This phase often lasts several months to around a year.
Thawing (the recovery phase). Range of motion gradually returns and pain continues to settle. This phase is the longest, often running a year or more.
Left entirely alone, the whole course commonly takes two to three years. That is the fact that surprises people most, and it is why "wait and see" is a poor plan on its own.
The reason phase matters clinically: the same treatment applied in the wrong phase can make things worse. Aggressive stretching during the painful freezing phase tends to increase irritation and pain without buying range. The same techniques applied during the frozen and thawing phases are far more productive. A physiotherapist's first job is working out where you are.
How frozen shoulder is distinguished from other shoulder problems
Shoulder pain has many causes, and they are managed differently. The pattern that points toward frozen shoulder is loss of passive range of motion, meaning your shoulder is restricted even when someone else moves your arm for you. External rotation, turning the forearm outward with the elbow at your side, is usually affected early and noticeably.
By contrast, a rotator cuff problem more typically limits what you can lift yourself while leaving passive movement relatively preserved. This distinction is straightforward for a clinician to assess and is worth getting right, because the treatment paths diverge from there.
Frozen shoulder is also more common in people with diabetes and in those with thyroid conditions, and it can follow a period of shoulder immobilisation after an injury or surgery. If you have recently had your arm in a sling and stiffness is setting in, that is worth mentioning early.
If your shoulder problem followed surgery, our guide to shoulder surgery recovery at home covers that pathway, which is a different situation from primary frozen shoulder.
What treatment involves in each phase
During the freezing phase, the aims are settling pain and preserving the range you still have. That means gentle movement within a comfortable range, positioning and sleep strategies (this phase wrecks sleep, and addressing it is genuinely part of treatment), and education about what is happening. Pushing hard here is counterproductive.
During the frozen phase, the emphasis shifts to regaining movement. Hands-on mobilisation and a progressive stretching program become the core of treatment. Evidence supports higher-grade mobilisation techniques for improving range of motion at this stage. This is also where consistency between sessions matters most.
During the thawing phase, the work is restoring full range and rebuilding strength, since months of restricted use leave the shoulder and shoulder blade muscles deconditioned. Finishing this phase properly is what determines whether you get back to full overhead function or settle for "mostly better."
The prognosis with appropriate management is generally good. Most people regain near-normal or normal shoulder function, and early, phase-appropriate treatment is associated with better outcomes than waiting it out.
Why treating this at home works well
Sleep is part of the problem, so the bedroom is part of the assessment. Frozen shoulder pain is famously worse at night. Working out pillow positions and sleeping postures in your actual bed is more useful than describing it from a treatment table.
The functional tests are your real tasks. Reaching a high cupboard, doing up a bra strap, getting a coat on, reaching the seatbelt. These are the movements that matter, and they are easiest to assess and practise where you actually do them.
This is a long condition, and consistency decides the outcome. A course of treatment spanning months succeeds or fails on whether you keep going. Removing the commute removes the most common reason people stop.
Driving may be uncomfortable. Reaching for the wheel or checking a blind spot can be painful, which makes travelling to a clinic for shoulder treatment a slightly absurd requirement. We come to you across Vancouver, North and West Vancouver, Burnaby, New Westminster, the Tri-Cities, Surrey, and Richmond.
For persistent pain that has been present a long time, our chronic pain management approach may also be relevant alongside shoulder-specific work.
When to see a doctor first
Most frozen shoulder is managed conservatively, but some presentations need medical assessment before starting physiotherapy. See your doctor or seek urgent care if you have:
- Shoulder pain following significant trauma, where a fracture or dislocation needs excluding
- A shoulder that is hot, red, and swollen, particularly with fever
- Sudden inability to move the arm at all after an injury
- Numbness, tingling, or weakness spreading down the arm
- Shoulder pain with chest pain, shortness of breath, or jaw pain, which can indicate a cardiac problem and needs emergency assessment
- Unexplained weight loss or night sweats alongside the shoulder pain
Physiotherapy does not replace medical assessment. Your physiotherapist screens for these and refers you on where needed.
Costs and billing
Home visits across Greater Vancouver are $180 for a 45 minute assessment and $210 for 60 minutes, with kinesiology and rehabilitation assistant sessions from $130. We bill private pay, ICBC, and WorkSafeBC separately, so tell us at booking which applies. See our fees page for details.
Frequently Asked Questions
How long does frozen shoulder take to resolve?
Without treatment, the full course from first pain to resolution commonly runs two to three years. Phase-appropriate physiotherapy is aimed at improving pain and function along the way and supporting a better end result, rather than skipping the process entirely.
Should I stretch through the pain?
Not during the early painful phase. Aggressive stretching while the shoulder is highly irritable tends to increase pain without gaining range. Stretching and mobilisation become genuinely productive in the frozen and thawing phases, which is why identifying your phase comes first.
How do I know if it is frozen shoulder or a rotator cuff problem?
The distinguishing feature is passive range of motion. In frozen shoulder the shoulder is stiff even when someone else moves your arm, and external rotation is usually restricted early. Rotator cuff problems more typically limit active lifting while passive movement stays relatively free. A physiotherapist can assess this directly.
Can frozen shoulder come back or affect the other side?
It is uncommon for the same shoulder to be affected twice, but some people go on to develop it in the opposite shoulder. Mention any previous episode at your assessment, since it is useful context.
Does having diabetes change anything?
Frozen shoulder is more common in people with diabetes and can be more stubborn. It does not change the overall approach, but it is worth telling your physiotherapist so expectations and pacing are set realistically.
Book an assessment
If your shoulder has been stiffening for weeks and nobody has explained where you are in the process, an assessment is the place to start.
