The inability to move your right shoulder, especially if accompanied by pain and stiffness, could be due to a condition known as frozen shoulder, technically called adhesive capsulitis.
Understanding Frozen Shoulder (Adhesive Capsulitis)
Frozen shoulder is a condition where the connective tissue surrounding the shoulder joint, known as the capsule, thickens and becomes stiff, restricting movement and causing pain. Think of it like glue forming inside your shoulder, making it hard to rotate or lift your arm.
What Happens in a Frozen Shoulder?
- Thickening of the Capsule: The normally flexible tissue around the shoulder joint becomes thick and tight.
- Scar Tissue Formation: Bands of scar tissue (adhesions) develop within the capsule.
- Decreased Synovial Fluid: The fluid that lubricates the joint decreases, further hindering movement.
Possible Causes of Frozen Shoulder
While the exact cause isn't always known (idiopathic frozen shoulder), some factors increase your risk:
- Injury or Surgery: Shoulder injuries or surgeries can sometimes trigger frozen shoulder.
- Immobility: Periods of inactivity due to a broken arm, stroke, or other medical conditions can contribute.
- Systemic Diseases: Certain medical conditions are associated with a higher risk:
- Diabetes
- Thyroid disorders (hypothyroidism or hyperthyroidism)
- Cardiovascular disease
- Parkinson's disease
Symptoms of Frozen Shoulder
Frozen shoulder typically progresses through three stages:
- Freezing Stage: Gradual onset of pain with increasing stiffness. This stage can last from 2 to 9 months.
- Frozen Stage: Pain may lessen, but stiffness remains significant, severely limiting range of motion. This stage typically lasts 4 to 12 months.
- Thawing Stage: Gradual return of motion. This stage can last from 5 to 24 months.
What to Do if You Suspect Frozen Shoulder
- Consult a Doctor: It's crucial to see a doctor for proper diagnosis. They will perform a physical exam to assess your range of motion and may order imaging tests (like X-rays or MRI) to rule out other conditions.
- Pain Management: Over-the-counter pain relievers like ibuprofen or naproxen can help manage pain and inflammation.
- Physical Therapy: A physical therapist can guide you through exercises to improve range of motion and reduce stiffness.
- Injections: In some cases, corticosteroid injections into the shoulder joint can help reduce inflammation and pain.
- Surgery (Rare): Surgery, such as manipulation under anesthesia or arthroscopic capsule release, is rarely needed but may be considered if other treatments are ineffective.
In summary, your inability to move your right shoulder is most likely caused by frozen shoulder, but it's essential to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.
