You might be experiencing difficulty rotating your shoulder due to a condition called adhesive capsulitis, more commonly known as frozen shoulder.
Understanding Frozen Shoulder
Frozen shoulder develops when the tissues surrounding your shoulder joint become inflamed and stiff. This restricts the normal range of motion, making it difficult to rotate your arm. The reference provided explains that:
- Inflammation and Adhesions: Intermittent use of the shoulder can cause inflammation. This inflammation can lead to the growth of adhesions—scar-like tissue—between the surfaces of the shoulder joint, restricting movement.
- Lack of Synovial Fluid: The shoulder joint relies on synovial fluid to lubricate the space between the arm bone and the socket, facilitating smooth movement. In frozen shoulder, there is often a lack of this fluid, further hindering rotation.
Key Factors Contributing to Limited Shoulder Rotation
The table below summarizes the factors that reduce your shoulder's ability to rotate:
| Factor | Explanation |
|---|---|
| Inflammation | Swelling within the joint capsule restricts space for movement. |
| Adhesions | Scar-like tissue that forms between joint surfaces, physically limiting rotation. |
| Reduced Synovial Fluid | Less lubrication makes it harder for the bones to slide smoothly during rotation, leading to stiffness. |
How This Impacts Rotation
When you attempt to rotate your shoulder, the combination of inflammation, adhesions, and lack of lubrication creates resistance. This can lead to:
- Pain: Attempting to force movement can be painful.
- Stiffness: The shoulder feels tight and difficult to move.
- Limited Range of Motion: You'll find it difficult to move your arm in a full circle or even reach behind your back.
What To Do
If you suspect you have frozen shoulder, it's important to:
- Consult a doctor for a diagnosis and to rule out any other causes.
- Follow recommended treatment plans which might include physical therapy, medication, or in some cases, surgery.
- Engage in recommended exercises to gradually improve range of motion.
