shoulder pain

My husband fell on his shoulder He has had previous surgery for a dislocated shoulder. the exray showed nothing but he is in extreme pain.  Cannot move his arm at all   Can there be that much pain from a strain

Certainly a bad contusion about the shoulder can be a sinicant cause of pain. However, not all injuries to the shoulder are visible on x-rays.  For example, a torn rotator cuff, or a torn labrum can both cause significant pain. Along with his inability to raise his arm, I would be concerned about a torn rotator cuff. If his symptoms persist, an MRI would be helpful.
