Pain and stiffness of the shoulder can always be felt throughout the course of this injruy. Sometimes, in acute stages, pain can also refer down the arm but rarely goes past the elbow.
During the initial freezing stage, any movement of your shoulder causes pain, and your shoulder’s range of motion slowly starts to become limited.
Once in the frozen stage, pain may begin to diminish, however your shoulder becomes stiffer, and using it becomes more difficult. In a typical frozen shoulder, flexion is limited to 90º.
