Frozen Shoulder: Causes, Symptoms, Treatment, and Prevention

Frozen shoulder, also known as adhesive capsulitis, is a condition that leads to stiffness and pain in the shoulder joint, limiting its movement and function. While it can affect anyone, it is more common in people aged 40-60 and is seen more frequently in women than men. This article provides a comprehensive guide to understanding frozen shoulder, its causes, symptoms, treatment options, and preventive measures.

🧠 What Is Frozen Shoulder?

Frozen shoulder occurs when the capsule of the shoulder joint, which is a connective tissue that surrounds the shoulder joint, becomes thickened, tight, and inflamed. This causes the shoulder's range of motion to become severely limited and painful. Over time, the shoulder may become so stiff that it is almost impossible to move the arm freely.

Frozen shoulder typically progresses through three stages:

1. Freezing Stage (Painful Stage)

The shoulder starts to hurt, and its range of motion begins to decrease. Pain is often worse at night and can interfere with sleep.

2. Frozen Stage (Stiff Stage)

The pain may lessen, but stiffness increases. The shoulder becomes difficult to move, and daily activities may become challenging.

3. Thawing Stage (Recovery Stage)

Gradually, the range of motion starts to improve, and the shoulder becomes less stiff. This stage can last anywhere from a few months to several years.

🧠 Causes of Frozen Shoulder

The exact cause of frozen shoulder is still not fully understood, but several factors are believed to contribute to its development. Some common causes and risk factors include:

1. Injury or Surgery

A shoulder injury or surgery (especially for conditions like rotator cuff injuries or shoulder fractures) can lead to limited movement of the shoulder. When the shoulder is immobilized for an extended period, the tissues in the joint may stiffen, resulting in frozen shoulder.

2. Chronic Inflammation

Chronic inflammation in the shoulder joint can cause tissue thickening and scarring, which ultimately leads to stiffness. Conditions like arthritis, diabetes, and autoimmune diseases can contribute to this.

3. Immobilization

After an injury or surgery, if the shoulder is not moved for a long time, it can cause the joint capsule to contract and stiffen, increasing the risk of frozen shoulder.

4. Underlying Health Conditions

Certain health conditions have been linked to an increased risk of frozen shoulder:

  • Diabetes: People with diabetes are more likely to develop frozen shoulder.

  • Thyroid disorders: Hypothyroidism (underactive thyroid) can increase the likelihood of frozen shoulder.

  • Heart disease: Individuals with heart disease, especially those with a history of heart surgery, may be at a higher risk.

  • Parkinson's disease: Neurological disorders like Parkinson’s can also increase the risk.

5. Age and Gender

Frozen shoulder typically affects individuals between the ages of 40 and 60. Women, especially those between 40 and 60, are more likely to develop frozen shoulder than men.

⚠️ Symptoms of Frozen Shoulder

The primary symptom of frozen shoulder is pain and stiffness in the shoulder joint, which progressively worsens over time. Other symptoms may include:

  • Pain in the shoulder: Often felt in the outer shoulder and upper arm. It can also radiate down the arm and be aggravated by movement.

  • Stiffness: Difficulty moving the shoulder, especially when reaching overhead, behind the back, or out to the side.

  • Limited range of motion: Simple tasks like reaching for an object or dressing may become difficult.

  • Night pain: Pain may worsen at night, making it challenging to sleep.

  • Gradual onset: Symptoms develop slowly, often over a period of weeks or months.

🩺 How Is Frozen Shoulder Diagnosed?

To diagnose frozen shoulder, a healthcare provider will conduct a physical examination to assess pain levels and the range of motion in the shoulder. They may also ask about your medical history, including previous injuries or surgeries.

Diagnostic Imaging:

  • X-rays: While X-rays won’t show soft tissue changes, they can rule out other possible causes of shoulder pain, like arthritis or fractures.

  • MRI (Magnetic Resonance Imaging): An MRI can provide more detailed images of the shoulder joint and soft tissues, confirming the diagnosis of frozen shoulder and ruling out other conditions.

In some cases, an MRI or an ultrasound may be used to check for other underlying conditions like rotator cuff tears that might be contributing to the symptoms.

💊 Treatment for Frozen Shoulder

The treatment goal for frozen shoulder is to reduce pain, improve mobility, and restore function to the shoulder. Depending on the severity of the condition, treatment options may include:

1. Physical Therapy

Physical therapy is often the primary treatment for frozen shoulder. A physical therapist will guide you through exercises to improve your shoulder’s range of motion and strengthen the muscles surrounding the joint. The treatment often includes:

  • Stretching exercises to improve flexibility and reduce stiffness.

  • Strengthening exercises to restore muscle function and support the shoulder.

  • Joint mobilization techniques to gently manipulate the shoulder joint and increase mobility.

2. Medications

Over-the-counter NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen or naproxen can help reduce pain and inflammation associated with frozen shoulder.

In more severe cases, your doctor may prescribe stronger medications, such as oral corticosteroids or corticosteroid injections directly into the shoulder joint, to reduce inflammation and improve movement.

3. Heat and Cold Therapy

Heat packs or ice packs can be used to reduce pain and inflammation. Applying ice to the affected shoulder for 15-20 minutes at a time can help reduce inflammation, while heat may improve blood flow and ease muscle stiffness.

4. Shoulder Manipulation

In some cases, your doctor may recommend shoulder manipulation under anesthesia. During this procedure, the doctor will carefully move the shoulder joint to break up the adhesions (scar tissue) that cause stiffness. This is often followed by physical therapy to maintain range of motion.

5. Surgery

If other treatments fail to relieve symptoms, surgery may be considered. Surgery for frozen shoulder typically involves either removing scar tissue or releasing the shoulder capsule to improve movement. Surgery is usually a last resort, as most people recover well with non-surgical treatments.

🛡️ Preventing Frozen Shoulder

While frozen shoulder cannot always be prevented, certain practices can reduce your risk:

1. Stay Active

Regular shoulder exercises and stretching can help maintain flexibility and strength in the shoulder joint. This is particularly important after an injury or surgery.

2. Avoid Prolonged Immobilization

If you are recovering from an injury or surgery, avoid keeping the shoulder immobilized for an extended period. Gradually move the shoulder as recommended by your healthcare provider to prevent stiffness.

3. Seek Early Treatment

If you begin experiencing shoulder pain or stiffness, seek treatment early to prevent the condition from worsening. Early intervention can reduce the severity and duration of frozen shoulder.

📝 Conclusion

Frozen shoulder can be a frustrating and painful condition that limits mobility and interferes with daily activities. The key to successful treatment lies in early diagnosis and consistent physical therapy. With proper care, most people experience a full recovery, although the process can take time. If you suspect you have frozen shoulder, consult with a healthcare provider to determine the best course of treatment for your condition.
