Frozen shoulder may only affect a few individuals but the pain felt can be unbearable. While it has been said that this condition only causes pain and stiffness on the shoulders it can also be a hindrance in doing the things that you love like sports and other physical activities. Having this condition can cause an individual to be injured easily. Other risks involved with frozen shoulder are:

• It can be a sign of aging and in Japan this condition is referred to as “Fifties Shoulder”.
• It can result to a bad posture.
• The individual might be at risk of injuring himself during intensive sports.
• Manual tasks can be hard to perform.
• Diabetes patients (types I and II) might experience unbearable pain.
• Trauma
• It can lead to a fractured collar bone
• Surgery might be needed for serious cases but this option might not be possible for diabetic patients.

The real causes of the frozen shoulder syndrome are not really known. It has been said that it happens with no obvious reasons. Though there are a number of theories that might explain why it happens.

1. Hormonal: It usually happens to females especially during menopause.
2. Genetic: Some studies have shown that there is a genetic factor that causes frozen shoulder syndrome to develop. There were cases where in identical twins experienced this syndrome at the same time. The syndrome can also be inherited by all the members of the family.
3. Auto-immune: It is possible that the body, for sometime, applies a rejection type reaction to the shoulder that is injured, recognizing it as a foreign object. This can also explain why the shoulder is not able to return at the same side.
4. Postural: The most possible study is standing for long hours, round shouldered that can cause the shortening of one shoulder ligaments.
