Frozen shoulder typically develops slowly in three stages.  Freezing stage. Any movement of the shoulder causes pain, and the shoulder's ability to move becomes limited. This stage lasts from 2 to 9 months. Frozen stage. Pain might lessen during this stage. However, the shoulder becomes stiffer. Using it becomes more difficult. This stage lasts from 4 to 12 months. Thawing stage. The shoulder's ability to move begins to improve. This stage lasts from 5 to 24 months.  For some people, the pain worsens at night, sometimes disrupting sleep.
