The rotator cuff tendons can be injured or torn by trying to lift a very heavy object with an extended arm. It can also happen from falling, or by trying to catch a heavy falling object. Symptoms of a torn rotator cuff include tenderness and soreness in the shoulder when using the shoulder. If the tendon has ruptured, you may not be able to raise the arm at all. It may be hard to sleep lying on that side. You may feel pain when pressure is put on the shoulder.
