You’re more likely to have a frozen shoulder if your shoulder pain developed gradually, is associated with increasing stiffness, and you cannot move your shoulder fully even when someone else tries to move it. Pain is often constant and may worsen at night.
A shoulder injury is more likely if the pain started suddenly after an injury or activity and movement is painful but still possible, especially when assisted.
If symptoms persist or worsen, a clinician can assess your shoulder and recommend the right treatment plan.
What Is a Frozen Shoulder?
Frozen shoulder is a condition medically known as adhesive capsulitis. It affects the shoulder joint when the surrounding joint capsule becomes inflamed, thickened, and tight.
Over time, this leads to:
- Increasing stiffness
- A gradual loss of movement
- Ongoing pain that may last for months
Frozen shoulder often develops slowly and can significantly affect quality of life, making simple arm movements difficult.
What Is a Shoulder Injury?
A shoulder injury usually occurs suddenly or after a specific event such as:
- A fall
- Heavy lifting
- Sports activity
- Injury or surgery
Common shoulder injuries include:
- Rotator cuff tear
- Tendon strains
- Shoulder impingement
- Ligament sprains
Unlike frozen shoulder, many injuries initially allow some movement, even if painful.
Key Differences Between Frozen Shoulder and a Shoulder Injury
1. How the Pain Starts
Frozen shoulder
- Gradual onset with no clear injury
- Dull or aching pain that worsens over time
- Pain often spreads to the upper arm
Shoulder injury
- Sudden pain after trauma or activity
- Pain linked to specific movements
- Symptoms often appear immediately
2. Movement Restriction
This is one of the most important differences.
Frozen shoulder
- You struggle to move your shoulder yourself
- A clinician also cannot move your arm fully for you
- Loss of movement affects all directions
Shoulder injury
- You may find it painful to move your arm
- However, a clinician can usually move the shoulder further when assisting
- Movement loss is often direction-specific
This loss of both active and passive range of motion is a key sign of frozen shoulder.
3. Pain Pattern
Frozen shoulder
- Persistent pain, often worse at night
- Stiffness is present even at rest
- Pain may continue even without movement
Shoulder injury
- Pain is usually triggered by certain activities
- Pain may improve with rest
- Stiffness is less constant
4. Progression Over Time
Frozen shoulder
- Symptoms worsen gradually
- Shoulder becomes progressively stiffer
- Condition develops over months
Shoulder injury
- Symptoms often improve with time
- Pain may settle as healing occurs
- Recovery may take weeks rather than months
Symptoms of Frozen Shoulder to Look Out For
Common symptoms of frozen shoulder include:
- Persistent shoulder pain with no obvious cause
- Increasing stiffness over time
- Difficulty lifting the arm or rotating it
- Pain extending into the upper arm
- Difficulty dressing, driving, or sleeping
If these symptoms are present for several weeks or months, frozen shoulder may be the cause.
Can You Have Both?
Yes. In some cases, a shoulder injury can trigger frozen shoulder, particularly after:
- Prolonged immobilisation
- Surgery
- A period of reduced movement
This is why early assessment is important if recovery from an injury stalls or stiffness worsens.
When Should You See a Clinician?
You should seek assessment if:
- Shoulder pain lasts longer than a few weeks
- Movement continues to worsen
- Pain affects sleep or daily activities
- You cannot lift or rotate your arm properly
Early diagnosis allows the correct treatment plan to begin sooner and helps prevent long-term stiffness.

Key Takeaway
If your shoulder pain developed gradually, worsens over time, and severely limits movement even when assisted, frozen shoulder is more likely than a simple injury. Early assessment by a clinician can make recovery easier and faster.
Frequently Asked Questions
How do I know if I have a frozen shoulder?
Frozen shoulder causes gradual pain and increasing stiffness, with loss of movement even when a clinician tries to move the arm.

Does frozen shoulder get worse over time?
Yes, symptoms typically worsen gradually before improving, unlike most injuries which improve with rest.
When should I see a clinician?
If shoulder pain or stiffness lasts more than a few weeks or affects daily activities, assessment is recommended.
