Frozen shoulder, known clinically as adhesive capsulitis, is a condition that causes shoulder pain and a progressive loss of range of motion. It can be frustrating and slow to resolve, but understanding how it behaves makes it far easier to manage. This guide explains the three stages of frozen shoulder, how long recovery typically takes, what causes it, and how physiotherapy helps you regain range of motion and ease the shoulder pain along the way.
What Is Frozen Shoulder?
Frozen shoulder, or adhesive capsulitis, is a condition where the capsule surrounding the shoulder joint becomes inflamed, thickened and tight. This restricts movement and causes shoulder pain, often significantly reducing your range of motion. It affects roughly 2 to 5 percent of people, most commonly between the ages of 40 and 60, and is more common in women.
It can develop on its own with no clear cause, known as primary or idiopathic frozen shoulder, or after a period of shoulder immobility such as following an injury or surgery, known as secondary frozen shoulder.
The 3 Stages of Frozen Shoulder
Frozen shoulder is traditionally described as progressing through three stages. The timeframes vary considerably from person to person, so treat them as a typical guide rather than a fixed schedule.
Stage 1: Freezing (0 to 3 Months)
The freezing stage is dominated by pain. Shoulder pain gradually increases and is often worse at night, and you begin to lose range of motion as movement becomes more uncomfortable. This is usually the most painful stage, and the frozen shoulder symptoms can come on gradually enough that it is easy to dismiss early on.
Stage 2: Frozen (3 to 9 Months)
In the frozen stage, the pain often begins to ease, but stiffness takes over. Your range of motion is at its most restricted here, and everyday tasks like reaching overhead, dressing or reaching behind your back become difficult. The shoulder is genuinely stiff rather than simply sore.
Stage 3: Thawing (9 to 18 Months)
In the thawing stage, range of motion gradually returns and the frozen shoulder symptoms steadily improve. Recovery can be slow, but movement and function progressively come back. This is where consistent, guided rehabilitation makes a real difference to how fully and how quickly you recover.
What Causes Frozen Shoulder?
The exact cause of primary frozen shoulder is not fully understood, but several factors increase the risk. Diabetes is the strongest, with people who have diabetes considerably more likely to develop adhesive capsulitis, often with more severe or prolonged symptoms. Thyroid conditions, particularly hypothyroidism, also raise the risk.
Secondary frozen shoulder can follow a period of reduced shoulder movement, such as after an injury, surgery or prolonged immobilisation. In these cases, keeping the shoulder moving where appropriate is part of prevention.
How Is Frozen Shoulder Treated?
Most cases of frozen shoulder are managed without surgery. Treatment aims to control shoulder pain, maintain and then restore range of motion, and support you through what can be a long recovery.
Physiotherapy
Physiotherapy is central to frozen shoulder management. A tailored program of appropriate stretching, range of motion work and progressive strengthening, matched to the stage you are in, helps manage symptoms and restore function. What is appropriate in the painful freezing stage differs from what helps in the thawing stage, which is why guided, stage-specific rehabilitation matters.
Pain Management
In the painful stages, managing shoulder pain allows you to keep the shoulder moving. Options such as anti-inflammatory medication or a corticosteroid injection are sometimes used alongside physiotherapy, particularly early on. These decisions are made with your doctor.
When Surgery Is Considered
Surgery is reserved for the minority of cases that do not respond to a good course of conservative treatment. Even then, physiotherapy afterwards is essential to a good outcome.
How BeFit Can Help
Frozen shoulder is far easier to manage with guidance than on your own, particularly because the right approach changes as you move through the stages. Our general physiotherapy team can assess your shoulder, confirm the diagnosis and build a stage-appropriate plan, and our sports physiotherapy team can help you rebuild strength and range of motion as you recover. No referral is required.
Frequently Asked Questions
How long does frozen shoulder last?
Frozen shoulder typically progresses through three stages over roughly one to two years, though this varies considerably. Some people recover faster, while others have symptoms that linger, particularly where diabetes is involved. Guided rehabilitation can support a smoother recovery.
What are the first symptoms of frozen shoulder?
The earliest frozen shoulder symptoms are usually gradually increasing shoulder pain, often worse at night, along with a developing loss of range of motion. Because it comes on slowly, it is easy to miss in the early freezing stage.
Can frozen shoulder be treated without surgery?
Yes. Most cases are managed with physiotherapy and pain management rather than surgery. Stage-appropriate rehabilitation helps control shoulder pain and restore range of motion. Surgery is reserved for cases that do not respond to conservative care.
Is frozen shoulder linked to diabetes?
Yes. Diabetes is the strongest known risk factor for frozen shoulder, and people with diabetes are significantly more likely to develop it, sometimes with more severe or prolonged symptoms. Thyroid conditions also increase the risk.
