“Why Is My Shoulder So Stiff? Understanding Frozen Shoulder.”

If you’ve ever had shoulder pain that gradually worsened until even simple movements became difficult, you may have experienced frozen shoulder, also known as adhesive capsulitis.

Frozen shoulder is a common condition that causes pain, stiffness, and reduced movement in the shoulder joint. It can be frustrating because symptoms often develop slowly and recovery can take time but understanding the condition can make the process much easier to manage.

What is Frozen Shoulder?

The shoulder is a highly mobile ball-and-socket joint. Surrounding this joint is a soft tissue capsule that helps support and stabilise movement.

In frozen shoulder, this capsule becomes inflamed, thickened, and tight, leading to pain and significant restriction in movement. Over time, scar-like tissue can develop, making the shoulder feel stiff and “stuck.”

In simple terms, the tissues around the shoulder joint tighten up and lose flexibility, making movement increasingly difficult.

Who Gets Frozen Shoulder?

Frozen shoulder commonly affects people between 40 and 60 years of age, and is more frequently seen in women.

You may also be at greater risk if you:

• Have diabetes

• Have recently had shoulder surgery and or injury

• Have had prolonged immobilisation, such as wearing a sling

• Have been less active due to pain or other health conditions

Sometimes, frozen shoulder develops without any obvious trigger.

The 3 Stages of Frozen Shoulder

Stage 1: Freezing Stage (Painful Stage)

Because movement becomes painful, people naturally start avoiding certain positions and activities, which can contribute to further stiffness. Often described as “My shoulder hurts every time I move it, and it’s getting worse.”

Stage 2: Frozen Stage (Stiff Stage)

At this stage, the shoulder capsule has become tight and less flexible, significantly limiting normal movement. often described as “The pain is a little better, but now I can barely move my shoulder.”

Stage 3: Thawing Stage (Recovery Stage) often described as “The shoulder is finally starting to loosen and move again.” Many people notice small improvements over time before regaining more normal function.

Will Frozen Shoulder Go Away?

In many cases, frozen shoulder improves over time, although recovery can be slow.

Some people regain full movement, while others may be left with mild stiffness or occasional discomfort.

The good news is that appropriate treatment can help reduce pain, improve function, and support recovery throughout each stage.

Treatment may include:

• Education and advice

• Activity modification

• Gentle rehabilitation exercises

• Manual therapy

• Pain management strategies

• Cortisone injections (in some cases)

• Referral for specialist care if needed

Importantly, treatment often depends on which stage of frozen shoulder you’re in.

The Key Takeaway

Frozen shoulder usually follows a predictable pattern:

Pain → Stiffness → Recovery

Or more simply:

• Freezing = painful

• Frozen = stiff

• Thawing = improving

Although frozen shoulder can be painful and frustrating, understanding the condition and receiving the right guidance can make a significant difference in recovery.

If you’re experiencing persistent shoulder pain or stiffness, early assessment can help determine whether frozen shoulder is the cause and what treatment approach is most appropriate.
