Frozen Shoulder

Overview

Frozen shoulder is a painful condition in which your shoulder movement becomes limited. Another name for frozen shoulder is adhesive capsulitis.

Frozen shoulder occurs when the strong connective tissue surrounding your shoulder joint (called the shoulder joint capsule) becomes thick, stiff and inflamed. The joint capsule contains the ligaments that attach the top of your upper arm bone (humeral head) to your shoulder socket (glenoid), firmly holding the joint in place. This is more commonly known as a ball-and-socket joint.

The condition is called “frozen” shoulder because the more pain you feel, the less likely you’ll use your shoulder. Lack of use causes your shoulder capsule to thicken and become tight, making your shoulder even more difficult to move — it’s “frozen” in its position.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.

The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:

High blood pressure.
Diabetes.
Heart failure.
Some types of heart valve disease.

Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:

Control high blood pressure, high cholesterol and diabetes.
Don't smoke or use tobacco.
Eat a diet that's low in salt and saturated fat.
Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
Get good sleep. Adults should aim for 7 to 9 hours daily.
Maintain a healthy weight.
Reduce and manage stress.
