Frozen Shoulder: The Three Stages and How Physiotherapy Helps

A frozen shoulder is one of the most frustrating shoulder conditions because it affects sleep, dressing, driving and work — often for months. The name sounds dramatic, but it describes a real process: the capsule around the shoulder joint becomes inflamed and then contracts, limiting movement in several directions.

It is not simply a “tight muscle.” That is why stretching harder is not always the answer.

What does frozen shoulder feel like?

Common signs include:

• Pain that builds gradually, often worse at night
• Difficulty reaching behind the back or overhead
• Loss of movement in several directions, especially rotating the arm outward
• Pain with sudden movements or when lying on the affected side
• Stiffness that persists even when the pain settles

The condition usually affects one shoulder, although the other side can be involved later. It is more common in people with diabetes and thyroid conditions, and it can occur after a period of shoulder immobilisation.

The three stages

1. The painful or freezing stage

Pain is the main feature. Movement starts to tighten, and sleep can be disrupted. In this phase, aggressive stretching can increase irritation. The priorities are pain management, gentle movement, education and practical strategies for daily tasks.

2. The frozen stage

Pain may ease, but stiffness becomes more prominent. Reaching, fastening clothing and lifting become difficult. This is often when people become frustrated because the pain is better but the movement is still limited. Graded mobility and strength work become more important.

3. The thawing stage

Movement gradually returns. The shoulder may still feel weak or unfamiliar, especially in overhead positions. Rehabilitation focuses on strength, endurance and returning to the activities you had stopped.

The stages are not perfectly neat. You may have a painful day in the frozen stage or feel progress one week and not the next. Treatment should follow what your shoulder is doing now, not a rigid calendar.

How physiotherapy helps

Physiotherapy cannot always shorten the natural history of frozen shoulder, but it can help you cope better and function more comfortably.

In the painful phase, we focus on settling irritation, maintaining comfortable movement and finding sleep positions that reduce pain. Hands-on treatment may provide short-term relief. We also review whether a medical appointment for pain relief is appropriate.

In the frozen phase, we use graded mobility exercises and begin strengthening the shoulder blade and rotator cuff within a comfortable range. The aim is to restore the movement you need for daily life, not to force a number.

In the thawing phase, we progress loading and functional tasks. That might include reaching overhead, carrying, pushing, pulling or returning to sport.

What you can do between sessions

• Keep moving gently rather than resting completely.
• Use positions that make sleep more comfortable.
• Avoid repeatedly testing the shoulder to see if it still hurts.
• Follow the specific exercises you have been given rather than copying random routines online.
• Manage diabetes and other health conditions with your doctor.

When to book an assessment

Book a physiotherapy assessment if shoulder pain has lasted more than a few weeks, is waking you at night, or is limiting your daily activities. If you have had a fall, cannot lift your arm at all after an injury, or have new weakness, numbness or fever, seek medical care promptly.
