Frozen Shoulder: Exercises, Stages, and When Physiotherapy (or Injection Therapy) Is Needed

If you are struggling to reach into a high cupboard, put on a coat, or sleep on your side because of a deep, aching shoulder pain, you are not alone. Frozen shoulder is a remarkably common condition, particularly for individuals in their 40s to 60s, and it often appears without any prior injury.

While many people assume they just need to stretch more or wait it out, managing a frozen shoulder requires the right clinical treatment at the right time. Doing the wrong exercises too early can actually make the pain worse.

Here is a clinical look at what is happening inside your joint, the distinct stages of recovery, and when to consider physiotherapy or injection therapy at our Preston clinic.

What is a Frozen Shoulder?

Clinically known as adhesive capsulitis, a frozen shoulder occurs when the strong connective tissue surrounding your shoulder joint (the capsule) becomes inflamed, thickens, and tightens. This tightening reduces the space needed for smooth movement, resulting in severe stiffness and a sensation that the joint is physically "locked".

The Three Stages of a Frozen Shoulder

A frozen shoulder does not happen overnight. It is a progressive condition that follows three distinct phases. Knowing which stage you are currently in is crucial for determining the safest and most effective treatment.

1. The Freezing (Painful) Stage

• Duration: Typically lasts between 2 to 9 months.

• Symptoms: This stage is characterised by a gradual onset of diffuse, severe pain that often worsens at night and severely disrupts sleep.

• What is happening: The shoulder capsule is actively inflamed and highly reactive.

2. The Frozen (Stiffening) Stage

• Duration: Often lasts for 4 to 12 months.

• Symptoms: The severe pain begins to subside, but the shoulder becomes incredibly stiff. You will notice a significant loss of movement, particularly when trying to lift your arm or rotate it outwards.

• What is happening: The active inflammation settles, but the capsule has now formed fibrotic tissue and has physically stuck to the bone.

3. The Thawing Stage

• Duration: Takes about 5 to 26 months to complete.

• Symptoms: The stiffness gradually lifts, and range of motion slowly returns.

• What is happening: The tightened capsule begins to loosen, allowing the shoulder to function normally again.

Physiotherapy and Exercises: Getting It Right

The most common mistake patients make is aggressively forcing stretches during the "Freezing" stage. When the joint lining is highly reactive, forceful manipulation, heavy stretching, or generic massage will provoke the tissue and increase your pain.

Instead, treatment must be clinically tailored to your current stage:

• During the Freezing Stage: The focus is entirely on pain management. A physiotherapist will guide you through gentle, pain-free mobility work, such as "pendulum exercises" where you let the arm hang and swing gently. We also provide strategies for sleeping positioning and postural support to unload the joint.

• During the Frozen Stage: As pain settles, treatment shifts to maintaining your available range and introducing isometric (static) strengthening. Safe home exercises, like using a wall to gently walk your fingers upward, can prevent further muscle wasting.

• During the Thawing Stage: This is where clinical physiotherapy shines. We implement a structured rehabilitation programme with progressive stretching, strengthening, and manual therapy to help you regain full movement and rebuild muscles that have weakened over the past year.

When is Injection Therapy Needed?

If you are in the early "Freezing" stage and experiencing escalating pain, severe night pain, or symptoms that prevent you from doing basic daily tasks, physical therapy alone may not be enough.

This is where Injection Therapy is clinically indicated. ActivLiving provides advanced injection therapy for lasting pain relief from persistent shoulder pain in Preston, Lancashire.

A corticosteroid injection delivers powerful anti-inflammatory medication directly into the shoulder joint capsule. By targeting the inflammation at its source during the most painful phase, an injection can:

• Dramatically reduce severe or worsening pain.

• Improve sleep quality by alleviating night pain.

• Provide enough comfort to allow you to meaningfully participate in your physiotherapy exercises.

Injections do not replace physiotherapy; rather, they create the window of pain relief necessary for your rehabilitation exercises to actually work.

Take the Next Step

Living with a frozen shoulder can be exhausting and frustrating, but you do not have to just wait for it to pass. If you are struggling with shoulder pain, stiffness, or sleep disruption, the right clinical intervention can change your trajectory.

Whether you need a structured exercise plan for the thawing phase or a clinical assessment for injection therapy during the painful freezing stage, our physio team in Preston, Lancashire is here to help.

FAQs

1. Can physiotherapy cure a frozen shoulder? 

Physiotherapy cannot instantly cure it, but it manages pain early on and restores your full range of motion during the final thawing stage.

2. Should I push through the pain when stretching? 

No. Forcing aggressive stretches during the initial freezing stage will only provoke the tissue and worsen your inflammation.

3. What are safe freezing shoulder exercises? 

During the most painful phase, stick to gentle, pain-free movements like pendulum swings to maintain basic joint mobility.

4. When is an injection recommended? 

A corticosteroid injection is highly recommended during the early freezing stage if severe pain is disrupting your sleep or daily tasks.

5. How long does a frozen shoulder take to heal? 

The entire process, moving through the freezing, frozen, and thawing stages, typically takes between one and three years.
