Frozen Shoulder Symptoms and Causes

25 Jun 2025Royal Medical Center

 

Frozen shoulder, or adhesive capsulitis, is a condition marked by stiffness, pain, and limited range of motion in the shoulder joint. It often develops gradually and worsens over time, impacting daily activities. Understanding its symptoms and causes is essential for early diagnosis and effective treatment to restore shoulder mobility.


What Is Frozen Shoulder? 


Frozen shoulder, or adhesive capsulitis, is a condition where the shoulder joint becomes stiff and painful due to inflammation and thickening of the joint capsule. It limits movement and typically develops gradually, progressing through stages of pain, stiffness, and recovery. It commonly affects adults between 40 and 60 years old.


What are the Symptoms of Frozen Shoulder?


Frozen shoulder develops in three main stages, each characterized by specific symptoms:


Freezing Stage


  • Pain: Begins gradually and often intensifies, especially at night.
  • Stiffness: Movement becomes increasingly restricted as the shoulder tightens.
  • Duration: This phase typically lasts anywhere from 6 weeks up to 9 months.


Frozen Stage


  • Pain: While pain may lessen during this stage, stiffness remains severe.
  • Limited Mobility: The shoulder becomes notably rigid, making everyday tasks difficult.
  • Duration: This stage usually spans 4 to 6 months.


Thawing Stage


  • Improvement: Shoulder movement starts to return gradually.
  • Decreasing Pain: Discomfort continues to fade as mobility improves.
  • Duration: Recovery can take between 6 months and 2 years.


It’s important to remember that the timeline and severity of symptoms can differ from person to person, with some experiencing longer or more intense phases.


What are the Causes and Risk Factors of Frozen Shoulder?


The precise cause of frozen shoulder is not fully understood, but several factors are known to increase the likelihood of developing the condition:


  • Age and Gender: It most commonly affects adults between 40 and 60 years old, with women being more frequently diagnosed than men.
  • Diabetes: Individuals with diabetes are significantly more prone to frozen shoulder, with studies indicating that up to 20% may develop it.
  • Thyroid Imbalances: Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroid conditions are linked to a higher risk.
  • Heart Conditions: Cardiovascular diseases, including heart disease, have been associated with increased susceptibility.
  • Neurological Disorders: Conditions such as stroke or Parkinson’s disease can impair shoulder movement, leading to stiffness over time.
  • Prolonged Immobilization: Extended periods of limited shoulder use, often due to injury or surgery, can contribute to the onset of frozen shoulder.


Recognizing these risk factors plays a key role in early identification and implementing preventive measures to maintain shoulder health.


Diagnosis


Diagnosing frozen shoulder involves a thorough physical examination by a healthcare professional. The doctor will assess the range of motion by moving the shoulder in various directions and may compare both shoulders to identify limitations. Imaging tests such as X-rays or MRI scans are not typically required, but may be used to rule out other conditions that could mimic the symptoms of frozen shoulder.


Treatment Options


The goal of treating frozen shoulder is to reduce pain and gradually restore range of motion. At Royal Medical Center, we provide personalized care plans based on each patient’s condition and recovery goals.


Non-Surgical Approaches


For most individuals, non-invasive therapies are highly effective:


  • Physical Therapy: Customized exercise routines focusing on gentle stretching and strengthening to gradually increase shoulder flexibility.
  • Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help relieve pain and reduce inflammation.
  • Corticosteroid Injections: These injections target the joint directly to minimize inflammation and provide pain relief, especially in the early stages.
  • Heat and Cold Applications: Alternating hot and cold therapy can help soothe soreness and loosen the joint for better movement.


Surgical Options


If conservative treatments don’t provide sufficient improvement, surgical procedures may be recommended:


  • Shoulder Manipulation Under Anesthesia: The shoulder is carefully moved while the patient is sedated, helping to break down adhesions that limit mobility.
  • Arthroscopic Release: A minimally invasive procedure where small instruments are used to cut and release the tightened joint capsule and remove scar tissue.


These surgical methods are generally reserved for more severe or persistent cases and are followed by a structured rehabilitation plan to ensure optimal recovery and functional return.


At Royal Medical Center, our team is committed to guiding patients through each step of treatment with expertise and compassionate care.


Rehabilitation and Recovery


Recovering from frozen shoulder is a gradual process that demands dedication and consistency:


  • Physical Therapy: Ongoing sessions with a therapist help rebuild shoulder strength and improve flexibility.
  • At-Home Exercises: Performing prescribed stretches and movements daily supports steady progress in restoring mobility.
  • Lifestyle Modifications: Making ergonomic changes at home or work and avoiding repetitive strain can ease shoulder stress during recovery.


With proper care, most people notice substantial improvement within 12 to 18 months, often regaining full or nearly full shoulder movement.


Preventive Measures


While not all cases of frozen shoulder are preventable, certain strategies can help reduce the risk:


  • Early Mobilization: After a shoulder injury or surgery, begin gentle range-of-motion exercises as recommended by your healthcare provider to prevent stiffness.
  • Regular Exercise: Maintain an active lifestyle with exercises that promote shoulder flexibility and strength, such as stretching and low-impact aerobic activity.
  • Manage Underlying Health Conditions: Keep chronic conditions like diabetes, thyroid disorders, and cardiovascular issues well-controlled to lower the risk of developing joint problems.


Taking these steps can help maintain shoulder health and reduce the likelihood of frozen shoulder.


When to Seek Medical Attention for Frozen Shoulder?


If you experience any of the following, it’s important to consult a healthcare professional:


  • Persistent shoulder pain lasting more than a few weeks
  • Difficulty moving your shoulder or arm
  • Pain that worsens at night and affects sleep
  • Stiffness that limits daily activities like dressing or lifting objects
  • History of shoulder injury or surgery followed by limited motion
  • Signs of inflammation, such as swelling, redness, or warmth around the joint
  • Inability to perform physical therapy exercises without increased pain
  • Shoulder symptoms accompanied by fever or unexplained weight loss


FAQs


Q: Is Frozen Shoulder the Same as a Rotator Cuff Injury?


A: No. While both can cause shoulder pain and reduced mobility, frozen shoulder involves thickening of the joint capsule, whereas rotator cuff injuries involve the tendons and muscles.


Q: How Long Does Frozen Shoulder Last?


A: Without treatment, it may last from 1 to 3 years. However, early intervention can significantly shorten recovery time.


Q: Can Frozen Shoulder Come Back?


A: It usually doesn’t recur in the same shoulder, but the opposite shoulder can be affected in up to 20-30% of cases.


Q: Does Frozen Shoulder Require Surgery?


A: Surgery is rarely needed. Most patients recover with physical therapy, medications, and injections.


Q: Is Frozen Shoulder Linked to Weather Changes?


A: Some people report increased stiffness and pain during cold or damp weather, but this varies by individual.
