What Are the First Signs of a Frozen Shoulder?
The earliest signs of frozen shoulder are usually a dull ache deep in the shoulder that gradually worsens, particularly at night, followed by a noticeable stiffness that makes everyday movements like reaching overhead or behind your back increasingly difficult.
Unlike a typical strain, the pain often builds gradually over weeks with no clear injury to explain it.
Catching it in this early "freezing" stage and starting physiotherapy promptly can help manage symptoms more effectively through the following stages, which can otherwise last a year or more. (1)
What Is Frozen Shoulder?
Frozen shoulder, also known as adhesive capsulitis, occurs when the capsule of tissue surrounding the shoulder joint becomes inflamed, thickens, and tightens. This gradually restricts the space within the joint, leading to increasing pain and a significant loss of movement over time.
It typically develops without an obvious injury, which is often what makes it confusing in the early stages. People frequently describe it as coming on gradually, seemingly out of nowhere.
What Are the Earliest Signs of Frozen Shoulder?
In the initial "freezing" stage, symptoms tend to build gradually rather than appear suddenly. Early signs to watch for include:
- A dull, aching pain deep within the shoulder, rather than sharp or localised pain
- Discomfort that's often worse at night, sometimes disrupting sleep
- Pain that increases with certain movements, particularly reaching overhead or behind the back
- A gradual reduction in range of motion, which may be subtle at first
- Increasing stiffness, especially first thing in the morning
Because the onset is gradual, it's common for people to initially dismiss these symptoms as a minor strain or general shoulder tightness, only recognising the pattern once movement becomes noticeably restricted.
How Does Frozen Shoulder Progress Over Time?
Frozen shoulder typically develops through three distinct stages and recognising which stage you're in can help guide the right treatment approach.
Freezing Stage (roughly 2–9 months)
Pain gradually increases, and shoulder movement becomes progressively more limited. This stage is often the most uncomfortable, particularly at night.
Frozen Stage (roughly 4–12 months)
Pain may start to ease slightly, but stiffness becomes the dominant issue. Movement remains significantly restricted, and daily tasks like dressing or reaching can become genuinely difficult.
Thawing Stage (roughly 6 months to 2 years)
Movement gradually begins to return, and pain continues to decrease. This stage can take considerable time, and consistent rehabilitation plays an important role in how fully and how quickly function returns.
Who Is Most at Risk of Developing Frozen Shoulder?
Certain factors appear to increase the likelihood of developing frozen shoulder, including:
- Being between 40 and 60 years old
- Being female, as frozen shoulder is more common in women
- Having diabetes or a thyroid condition
- A period of shoulder immobility, such as after surgery, a fracture, or a stroke
- A previous episode of frozen shoulder in the other shoulder
If you fall into one of these higher-risk groups and start noticing early symptoms, it's worth seeking an assessment sooner rather than waiting to see if it resolves on its own.
Why Does Catching Frozen Shoulder Early Matter?
Frozen shoulder can be a lengthy condition, often lasting anywhere from several months to a couple of years if left unmanaged. While it's not usually possible to prevent it outright, early intervention with physiotherapy can help to reduce pain and regain mobility more effectively. Maintaining as much movement as possible through the freezing and frozen stages allows for a smoother, more complete recovery during the thawing stage. (2)
Delaying treatment doesn't always necessarily change the overall timeline, but it can mean living with more pain and restriction for longer than necessary.
How Is Frozen Shoulder Treated?
Treatment is tailored to which stage you're in, since the right approach in the painful freezing stage looks quite different to what's appropriate once you're moving into the thawing stage. A typical physiotherapy plan may include:
- Guided mobility exercises to maintain and gradually restore range of motion
- Manual therapy to ease stiffness and support joint movement
- Pain management strategies, particularly during the more painful early stage
- A progressive strengthening programme as movement begins to return
In some cases, corticosteroid injections may also be considered to help reduce pain and inflammation, making it easier to engage with rehabilitation exercises during all stages of recovery. (3)

Frequently Asked Questions
How do I know if my shoulder pain is frozen shoulder and not something else?
Frozen shoulder tends to develop gradually without a clear injury, with pain that's often worse at night and a progressive reduction in range of motion, particularly with overhead or behind-the-back movements. A physiotherapist can help confirm the diagnosis through assessment.
How long does frozen shoulder last?
It typically progresses through three stages over a period of 6 months to 2 years or more: a painful freezing stage, a stiff frozen stage, and a gradually improving thawing stage.
Can frozen shoulder go away without treatment?
It can eventually resolve on its own, but this process is often slow and can leave lasting stiffness. Physiotherapy throughout each stage tends to lead to better pain management and a more complete recovery.
Who is most likely to develop frozen shoulder?
It's more common in people aged 40–60, women, and those with diabetes, thyroid conditions, or a recent period of shoulder immobility, such as after surgery or injury.
Is frozen shoulder the same as a rotator cuff injury?
No. Frozen shoulder involves tightening of the joint capsule itself, causing widespread stiffness, whereas a rotator cuff injury affects specific tendons and tends to cause more localised pain and weakness rather than a global loss of movement.
