Frozen shoulder:
why it takes
time
It arrives without an injury, hurts most at night, and then quietly stiffens. Understanding the stages explains why patience is part of the treatment.
Frozen shoulder is not treated with one intervention. It is managed differently in each of its three stages.

Key points
- Often begins without any injury, and is more common between 40 and 60
- Diabetes and thyroid disorders increase the risk considerably
- Pain dominates the first stage; stiffness dominates the second
- Night pain and difficulty reaching behind the back are typical
- Recovery is usually measured in months, and physiotherapy timing matters
Few orthopaedic conditions frustrate patients as much as frozen shoulder, or adhesive capsulitis. There is often no injury to explain it. Reaching for a seatbelt, fastening a blouse or lifting a bag from the back seat becomes suddenly impossible, and sleep is disturbed for weeks.
What is happening is that the capsule surrounding the shoulder joint becomes inflamed and then contracts, tightening around the joint like a shrinking sleeve. It is genuinely self-limiting in most people, but the course is long, and treatment that helps in one stage can aggravate another.
The threestages.
Stage one: painful, roughly two to nine months
Pain comes first and is often worse at night and when lying on the affected side. Movement is limited mainly because it hurts. This is the stage in which aggressive stretching does more harm than good, and in which pain control is the priority.
Stage two: stiff, roughly four to twelve months
Pain settles somewhat but the shoulder is now genuinely restricted. Reaching behind the back, combing hair or taking a shirt off becomes the limitation rather than the pain. This is when structured physiotherapy and stretching earn their place.
Stage three: thawing, roughly six to twenty-four months
Movement returns gradually. Most patients recover functional range, although a small proportion are left with a mild restriction that rarely affects daily life.
Who is more at risk
- People with diabetes, in whom it is both more common and often more stubborn
- Thyroid disorders
- A period of immobilisation, such as after a fracture or surgery
- A previous frozen shoulder on the other side
Because uncontrolled blood sugar prolongs the condition, managing diabetes is part of managing the shoulder, not a separate matter.
What actuallyhelps.
First, confirm it is a frozen shoulder
Rotator cuff tears, calcific tendinitis, arthritis of the shoulder and cervical spine problems can all mimic it. Examination distinguishes most of them, because frozen shoulder restricts movement in every direction, including when someone else moves the arm for you. X-rays are used to exclude other causes; MRI is not always necessary.
Stage-appropriate treatment
- Painful stage: pain relief, activity within comfort, gentle range-of-movement work, sleep positioning with a pillow supporting the arm
- Stiff stage: structured physiotherapy with sustained stretching, home exercises several times daily
- Selected cases: an image-guided injection into the joint can shorten the painful stage and make physiotherapy possible
- Resistant cases: where months of proper treatment have not restored useful movement, capsular release or examination under anaesthesia may be considered
What tends to slow recovery
- Resting the arm completely, which accelerates stiffening
- Forceful stretching during the painful stage
- Stopping exercises as soon as the pain improves
- Uncontrolled blood sugar
Recovery times differ widely between individuals. The stages above describe a common pattern, not a fixed schedule.
Frequentquestions.
How long does a frozen shoulder take to recover?
Most cases resolve over one to two years, and treatment aims to shorten the painful phase and preserve movement. Diabetes tends to lengthen the course.
Will an injection cure it?
An injection does not cure the condition, but a well-placed one can reduce pain enough to allow effective physiotherapy, which is what restores movement.
Should I keep using the arm?
Yes, within comfort. Complete rest is one of the reliable ways to make stiffness worse. Ordinary daily use is encouraged; forced stretching during the painful stage is not.
Can it affect the other shoulder later?
It can. A proportion of patients develop it on the opposite side at a later date, which is one reason underlying conditions such as diabetes are addressed alongside the shoulder.

Early assessment identifies which stage you are in, and that decides whether stretching will help you or set you back.
