Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in your shoulder joint.
When the tissues in your shoulder joint become thicker and tighter, scar tissue develops over time. As a result, your shoulder joint doesn’t have enough space to rotate properly. Common symptoms include swelling, pain, and stiffness. You’re more likely to have the condition if you’re between the ages of 40 and 60.
If you have a hormonal imbalance, diabetes, or a weakened immune system, you may be prone to joint inflammation. A long period of inactivity due to an injury, illness, or surgery also makes you more vulnerable to inflammation and adhesions, which are bands of stiff tissue. In serious cases, scar tissue may form. This severely limits your range of motion. Usually, the condition takes two to nine months to develop.
You become aware of a frozen shoulder when it begins to hurt. The pain then causes you to limit your movement. Moving the shoulder less and less increases its stiffness. Before long, you find that you can’t move your shoulder as you once did. Reaching for an item on a high shelf becomes difficult, if not impossible. When it’s severe, you might not be able to do everyday tasks that involve shoulder movement such as dressing.
