Key Takeaways
- Frozen shoulder moves through three stages – freezing, frozen and thawing – and can take one to three years to fully resolve.
- Most cases improve with physiotherapy and pain management. Surgery is only considered if these don't work.
- Women over 40, and people with diabetes or thyroid conditions, face a higher risk. Keeping the shoulder moving after any injury helps prevent it.
You reach for something on a high shelf, and the pain stops you halfway. Or you try to fasten your bra behind your back, and your arm simply won't go there anymore. You don’t remember any specific injury. Nothing obvious happened. Your shoulder has just quietly stopped working the way it used to.
That combination — pain with no clear cause, and movement that keeps getting worse — is what sends most people searching for answers. Frozen shoulder is one of the more common explanations, and one of the more misunderstood, because it doesn't behave like a typical injury.
What is a frozen shoulder?
Frozen shoulder (adhesive capsulitis) is a condition that causes pain, stiffness, and reduced movement in your shoulder joint.
Your shoulder is surrounded by a joint capsule made of connective tissue that helps keep the joint stable. In frozen shoulder, this capsule becomes inflamed, thickened, and tight. Scar tissue may also develop, making it difficult and painful to move your shoulder.
Unlike a shoulder injury that happens suddenly, frozen shoulder usually develops gradually over weeks or months. It typically affects one shoulder, although it can occasionally occur in both.
Symptoms of frozen shoulder
The two hallmark symptoms are shoulder pain and a shrinking range of motion. You may struggle to reach across the table, put on a shirt, or comb your hair. Everyday movements that once took no thought now need planning around.
The adhesive capsulitis usually moves through three stages. Each one feels different, and each can last for months.
Freezing stage (painful stage)
This is where the pain is worst. Any shoulder movement can trigger it, and it often disturbs your sleep at night. Your range of motion narrows as this stage progresses. It typically lasts six weeks to nine months.
Frozen stage (adhesive stage)
The pain usually eases here, but the stiffness remains, and sometimes worsens. You may find your shoulder simply won't go where you're asking it to. This stage generally lasts four to six months.
Thawing stage (Recovery stage)
Movement gradually returns, often very slowly. Pain is usually mild by this point, though it can still flare occasionally. Thawing can take anywhere from six months to two years, which is why patience becomes part of the treatment.
When should you see a doctor for frozen shoulder?
It is normal to have occasional shoulder pain after strenuous activity, but you should see a doctor if your pain or stiffness does not improve or begins to affect your daily life.
Seek medical attention if you:
- Have shoulder pain that lasts for more than a few weeks
- Notice increasing stiffness that makes it difficult to lift or move your arm
- Find it hard to perform everyday tasks, such as dressing, reaching overhead, or fastening your seatbelt
- Have shoulder pain that regularly wakes you up at night
- Develop shoulder stiffness after an injury or surgery
- Experience severe pain, swelling, redness, or fever, as these may indicate another condition that requires prompt medical attention
Early diagnosis can help rule out other shoulder conditions and allow treatment to begin before stiffness becomes more severe.
Causes of frozen shoulder
In many cases, you won’t have an obvious trigger for your symptoms. This is called primary frozen shoulder, and it’s the more common form. Inflammation causes the shoulder capsule to thicken and scar, shrinking the space your joint has to move in. Why this inflammation starts isn’t fully understood.
The secondary frozen shoulder has a clearer trigger. It often develops after a period where your shoulder was kept still – for example after a fracture, surgery, or an injury like a rotator cuff tear that made movement too painful. Prolonged immobility, even when it’s medically necessary at first, can set the process in motion.
What are the risk factors for frozen shoulder?
Knowing the risk factors for frozen shoulder may help you seek treatment before stiffness becomes severe.
You may be more likely to develop it if you:
- Are between 40 and 60 years old
- Are female (more common in women)
- Have thyroid disorders
- Have diabetes
- Have Parkinson's disease
- Have heart disease
- Have had a stroke
- Recently had shoulder surgery or an injury
- Have kept your shoulder immobilised for a prolonged period
People with diabetes are more likely to develop it and may experience more severe symptoms.

What are the complications and related diseases of frozen shoulder?
Without treatment, frozen shoulder can significantly affect your quality of life.
Possible complications include:
- Persistent pain
- Long-term shoulder stiffness
- Difficulty performing daily activities
- Reduced shoulder strength due to limited use
- Sleep disturbance caused by pain
This may also occur alongside conditions such as:
- Diabetes
- Thyroid disease
- Rotator cuff disorders
- Shoulder impingement
- Parkinson's disease
- Heart disease
Your doctor will assess whether another shoulder condition may be contributing to your symptoms.
Frozen shoulder vs rotator cuff injury: What's the difference?
Frozen shoulder and a rotator cuff injury can both cause shoulder pain, but they affect the shoulder differently and may require different treatments.
Because the symptoms can overlap, your doctor may perform a physical examination and recommend imaging tests, such as an ultrasound or MRI, to identify the underlying cause of your shoulder pain.
Diagnosis of frozen shoulder
Your doctor will ask about your symptoms, medical history, and when your shoulder pain began.
During a physical examination, they will assess:
- How far you can move your shoulder yourself (active range of motion)
- How far your doctor can move it (passive range of motion)
- Areas of tenderness
- Muscle strength
In thiscondition, both active and passive shoulder movements are usually restricted.
Imaging tests may also be recommended to rule out other conditions.
These may include:
- X-rays
- Ultrasound
- MRI scans
Although imaging cannot always confirm frozen shoulder, it can help identify problems such as arthritis or rotator cuff tears.
What is the treatment for frozen shoulder?
Treatment focuses on relieving pain, restoring shoulder movement, and helping you return to your normal activities.
Non-Surgical Treatments
Most people improve without surgery.
Your doctor may recommend:
- Pain-relieving medications
- Anti-inflammatory medicines
- Physiotherapy to improve shoulder mobility
- Gentle stretching exercises
- Heat or cold therapy
- Corticosteroid injections to reduce inflammation
- Hydrodilatation (joint distension), where sterile fluid is injected into the shoulder capsule to improve movement
Following your physiotherapy programme consistently is one of the most important parts of recovery.
Surgical Treatments
Surgery may be considered if your symptoms remain severe despite several months of non-surgical treatment.
Options include:
Manipulation under anaesthesia (MUA)
While you are asleep under anaesthesia, your surgeon gently moves your shoulder to break up tight scar tissue and improve movement.
Arthroscopic capsular release
This minimally invasive procedure uses small incisions and a tiny camera. Your surgeon carefully releases the tight shoulder capsule to improve your range of motion.
Most people continue physiotherapy after surgery to maintain the improved movement.
How to prevent frozen shoulder
This cannot always be prevented, but you can reduce your risk by keeping your shoulder moving whenever it is safe to do so.
You can help protect your shoulder by:
- Performing shoulder exercises after an injury or surgery as advised by your doctor
- Attending physiotherapy appointments
- Avoiding prolonged shoulder immobilisation unless recommended
- Managing medical conditions such as diabetes
- Maintaining good shoulder strength and flexibility
If you develop shoulder pain that limits movement, seek medical advice early before significant stiffness develops.

Frequently asked questions
This is not a permanent condition. Most people regain the majority of their shoulder movement over time, whether through non-surgical treatment or, less commonly, surgery. Full recovery can take one to three years, so "cured" here means resolved, not fixed overnight.
There's no shortcut here, and any claim of a fast fix should be treated with caution. Frozen shoulder resolves in stages, typically over one to three years. What actually helps is starting treatment early — pain management alongside guided physical therapy — rather than waiting until stiffness has set in further.
Recovery timelines vary, but the full course typically runs one to three years across all three stages. The freezing stage alone can last six weeks to nine months, the frozen stage four to six months, and thawing anywhere from six months to two years.
Most people regain the large majority of their shoulder movement. Some go on to experience mild residual stiffness for up to three years, even after treatment. A structured physiotherapy programme, followed through consistently, gives you the best chance of getting close to your original range.
This depends on which stage you're in, which is exactly why a physiotherapist should tailor your programme rather than a generic list. In the earlier, painful stage, gentle range-of-motion exercises are usually prioritised over strengthening. As stiffness eases in later stages, stretching and strengthening work together to rebuild full movement.
