My shoulder hurts when lifting weight , lifting the arm, put your hands behind your back and even sleep. And took 3 months. Could it be the rotator cuff ?
The pain at night , with activity above the head or stretching his arms behind his back , in addition to weakness, are all symptoms of rotator cuff problems . An MRI may confirm the diagnosis . Treatment depends on the severity of symptoms and the degree of damage to the rotator cuff .
