Frozen Shoulder Stages: How Long Each One Lasts

Frozen shoulder (adhesive capsulitis) usually moves through three stages. The freezing stage, when pain builds and movement starts to go, often lasts 2 to 9 months. The frozen stage, when pain eases but stiffness peaks, often lasts 4 to 12 months. The thawing stage, when movement slowly returns, often lasts 6 months to 2 years or more. The stages overlap, and the whole course commonly runs one to three years.

The ranges are wide because people vary a great deal. Which stage you are in today matters more, because it decides what kind of exercise and treatment makes sense this month. Some clinicians describe four stages, splitting off the early painful weeks; the ideas below fit either model.

Key takeaways

Three stages: freezing (pain rising, movement going), frozen (pain easing, stiffness at its worst), thawing (movement returning).
Typical lengths: freezing often 2 to 9 months, frozen often 4 to 12 months, thawing often 6 months to 2 years or more.
Overlap: the stages blend into each other. There is rarely a clear day when one ends.
Main signal of change: the balance between pain and stiffness. When night pain eases while stiffness stays, the shoulder has usually moved from freezing to frozen.
Treatment changes by stage: calming pain and keeping gentle movement early, firmer and longer stretching once pain settles, strengthening as range returns.

Where are you right now?

Pain is building and the arm is getting harder to move: read the freezing stage section below. Several shoulder problems look alike early on.
Months in, less pain, still very stiff: you are likely in the frozen stage. See that section and “If it isn’t going to plan”.
After a steroid injection or hydrodilatation: these are usually aimed at the painful stage, or at stiffness that has stalled. Your doctor’s plan for the following weeks comes first; the stage sections explain what the exercise side usually looks like.
Movement is coming back and you want to return to work or sport: see the thawing stage and the “When can I…” table.

Month by month, stage by stage

Freezing stage: often lasts 2 to 9 months

The shoulder aches deep in the joint, often down toward the outer upper arm. Night pain is common and lying on that side becomes hard. Turning the arm outward and reaching behind your back are usually the first movements to shrink.

What treatment tends to focus on: pain relief, sleep, and keeping the movement you have with gentle, frequent, comfortable movement. A steroid injection is most often considered in this stage, when pain is the main problem.
What usually does not help: forcing hard stretches into pain. The inflamed joint lining (capsule) tends to answer with a worse night.

Signs you are moving from freezing to frozen

Night pain eases: you wake less often, or can lie on that side for short spells.
Pain at rest settles: the shoulder is comfortable when you are not using it.
Stiffness stays the same or feels worse: this is expected and does not mean the shoulder is going backward.

Frozen stage: often lasts 4 to 12 months

Pain is lower, stiffness is at its peak. Dressing, reaching a back pocket, doing up a bra, and reaching a high shelf are the daily struggles.

What treatment tends to focus on: firmer stretching held for longer, because the capsule is now less irritable and can tolerate more. Some people are offered hydrodilatation (stretching the capsule with fluid) if movement has stalled.
What to expect: progress can feel flat for weeks. Measuring movement every few weeks shows change better than day-to-day feel.

Signs you are moving from frozen to thawing

Small gains that stay: a few more centimeters reaching behind your back that do not disappear by the next morning.
Everyday tasks get easier: washing your hair or putting on a jacket takes less effort.

Thawing stage: often lasts 6 months to 2 years or more

Movement returns gradually. Overhead reaching and turning outward usually come back last.

What treatment tends to focus on: continued stretching, plus strengthening of the shoulder and shoulder blade muscles so the arm can use the range it regains.
What to expect: many people get most of their movement back over two to three years. Some keep a small amount of stiffness that rarely limits daily life.

The stage you are in matters more than how many months it has been.

Where else this could be coming from

Rotator cuff problems: lifting the arm yourself hurts or feels weak, but someone else can often lift it further. In frozen shoulder, it is stiff whoever moves it.
Shoulder arthritis: stiffness with grinding, usually in older adults, with joint changes on an X-ray. Frozen shoulder X-rays are usually normal.
The neck: pain across the top of the shoulder or shoulder blade that changes with neck movement, sometimes with tingling into the arm. Shoulder movement itself is often near full.

Is this normal?

“I can’t tell which stage I am in.” Very common. The stages overlap, and many people sit between two for weeks. The pain-to-stiffness balance is a better guide than the calendar.
“The pain went down but I’m stiffer.” This is the usual shift from freezing to frozen.
“I had a good month, then a bad week.” Ups and downs are common in every stage and do not usually mean you have slipped back.
“My stages don’t match the numbers.” The ranges are averages. People with diabetes often take longer.

If it isn’t going to plan

It is month eight. The night pain finally let you sleep, but your arm still stops short of the seatbelt, and you have started to wonder whether the frozen stage will ever end. The thought is that the stiffness is now permanent.

The belief that it will loosen if you just wait is partly true. Most frozen shoulders do thaw, but the capsule responds to how it is loaded. Once pain settles, longer-held stretching gives the tissue a steady signal to lengthen.

If movement has not changed over two to three months in the frozen stage, or night pain is still waking you most nights after six months, get assessed by a physical therapist or doctor. Useful questions:

Stage: which stage do you think I am in, and what should change in my exercises because of it?
Measurement: which movements will we measure, and how often?
Options: would hydrodilatation or another procedure, such as a frozen shoulder release, suit me if progress stays flat?
Health checks: should my blood sugar or thyroid be tested?

When can I…

Activity	Typical range
Sleep on that side	Often not until late in the frozen stage or into thawing
Drive	Usually possible throughout if you can steer and reach the seatbelt safely
Reach overhead	Usually limited until the thawing stage, often returning last
Lift	Light loads close to the body are usually manageable; overhead lifting often waits for thawing
Desk work	Usually possible throughout with the keyboard and mouse close to you
Manual work or sport	Overhead and throwing tasks often limited until well into thawing

If you have had surgery, your surgeon’s protocol comes first.

Call your local emergency number or go to the emergency department if

Chest symptoms: shoulder pain comes with chest pain or pressure, breathlessness, sweating, or pain spreading to the jaw.
Injury: the shoulder looks out of shape after a fall, or you cannot move it at all after an injury.

See a doctor today if

Hot, swollen joint: the shoulder is red, hot or swollen, or you have a fever.
Arm changes: the arm becomes swollen, cold, pale or blue.

Get it checked soon if

No diagnosis: a painful, stiff shoulder has not been assessed and is not easing after 2 to 4 weeks.
Stalled stage: movement has not changed at all over several months.
Feeling unwell: unexplained weight loss, night sweats, or a history of cancer.
