In frozen shoulder, you are unable to move your shoulder joint as normal. The shoulder joint becomes like this because of inflammation and thickening of the lining of the fibrous tissues, or capsule, which surrounds the joint. The cause is not clear The exact cause or trigger is not clear, but some people relate the problem to an injury, which was often quite minor. Sometimes, it seems to follow other illness, such as bronchitis, angina, or a stroke. There may also be a link to diabetes.
Frozen shoulder is rare in young people.
One of the most common tests is to get the person to try to lift their arm to the horizontal level. This is impossible in frozen shoulder, and the arm can only be lifted a small way, if at all. Treatment may help, but recovery is slow There are a variety of different treatments, which can help increase mobility, and reduce the pain. However, the bad news is that recovery is usually slow, and may take 2 or 3 years. There is also an increased risk that the problem may recur, although this is far from inevitable.
