The inability to move your shoulder can stem from a variety of issues, ranging from temporary discomfort to more serious underlying conditions. The most common culprit is a condition called "frozen shoulder," but other possibilities exist.
Potential Reasons for Shoulder Immobility:
-
Frozen Shoulder (Adhesive Capsulitis): This condition causes stiffness and pain in the shoulder joint. The exact cause is often unknown, but it involves a thickening and tightening of the tissue surrounding the shoulder joint, restricting movement. It can develop after a period of immobility or injury.
-
Rotator Cuff Problems: The rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within your shoulder socket.
- Impingement: This occurs when tendons are compressed, leading to pain and limited movement.
- Tears: Rotator cuff tears can happen from sudden injury or gradual overuse. They can cause significant pain and weakness, making it difficult to move your shoulder.
-
Arthritis: Osteoarthritis or rheumatoid arthritis can affect the shoulder joint, causing pain, stiffness, and reduced range of motion.
-
Bursitis: Inflammation of the bursae (fluid-filled sacs that cushion the shoulder joint) can cause pain and restrict movement.
-
Injury: Direct trauma to the shoulder, such as a fracture or dislocation, can severely limit movement.
-
Other Conditions: In rare cases, shoulder immobility can be related to nerve damage, tumors, or infections.
What to Do Next:
If you are experiencing significant shoulder pain or difficulty moving your shoulder, it's important to consult a doctor for a proper diagnosis and treatment plan. They will likely perform a physical exam, and may order imaging tests such as X-rays or an MRI. Treatment options vary depending on the cause, but may include:
- Pain relievers: Over-the-counter or prescription medications.
- Physical therapy: Exercises to improve range of motion and strength.
- Corticosteroid injections: To reduce inflammation.
- Surgery: May be necessary for severe cases, such as rotator cuff tears or severe arthritis.
It's crucial not to ignore persistent shoulder pain or stiffness, as early intervention can often prevent the condition from worsening. Avoiding movement due to pain can sometimes exacerbate the problem, as seen in the development of frozen shoulder following a rotator cuff issue.
