The pain associated with a rotator cuff injury may include but is not limited to:

• A dull ache deep in the shoulder
• Disturbed sleep, particularly if you lie on the affected shoulder
• Difficulty combing your hair or reaching behind your back
• Accompanied by arm weakness

There is also what is called “referred pain”, where the pain related to a shoulder injury is not necessarily felt only in the shoulder area. This pain can radiate down your arm and may even cause pain in the wrist. Shoulder injuries may also cause tingling and numbness in the arm and fingers.
