A frozen shoulder (sometimes referred to as shoulder capsulitis) describes a condition in which the soft tissue which encapsulates the joint (joint capsule) becomes painful and inflamed. The process leads to a thickening of the local tissue, which causes the movements of the shoulder to become increasingly stiff (frozen). Fortunately, in most cases, frozen shoulder resolves over 2-3 years.
Frozen shoulder can occur after trauma to the shoulder, but more commonly occurs gradually with no injury or reason. Some people are at greater risk of developing a frozen shoulder:
- Female gender
- Age range 40-60
- Diabetic individuals
