Rotator Cuff Injuries (shoulder pain)
Rotator cuff muscles are the four muscles around the shoulder joint.
Many shoulder pain conditions are caused by damage to one or more of the rotator cuff muscles, or to the soft tissues around the shoulder joint.
Symptoms of rotator cuff injuries include increased chronic pain at night causing problems with sleeping on the injured side, restricted movement of the shoulder and loss of strength.
Rotator cuff injuries are often diagnosed as frozen shoulder as the same muscles are affected in both conditions.
