What is Frozen Shoulder?
Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in your shoulder joint. Signs and symptoms typically begin gradually, worsen over time and then resolve, usually within one to three years. Your risk of developing frozen shoulder increases if you’re recovering from a medical condition or procedure that prevents you from moving your arm — such as a stroke or a mastectomy. Treatment for frozen shoulder involves range-of-motion exercises and, sometimes, corticosteroids and numbing medications injected into the joint capsule. In a small percentage of cases, arthroscopic surgery may be indicated to loosen the joint capsule so that it can move more freely. It’s unusual for frozen shoulder to recur in the same shoulder, but some people can develop it in the opposite shoulder.
Symptoms of Frozen Shoulder:
Frozen shoulder typically develops slowly, and in three stages. Each stage can last a number of months.
- Freezing stage. Any movement of your shoulder causes pain, and your shoulder’s range of motion starts to become limited.
- Frozen stage. Pain may begin to diminish during this stage. However, your shoulder becomes stiffer, and using it becomes more difficult.
- Thawing stage. The range of motion in your shoulder begins to improve.
For some people, the pain worsens at night, sometimes disrupting sleep.
