Another common cause for rotator cuff injuries is exerting overhead activity. Perhaps you threw the neighbor’s frisbee back over the fence a little too hard, or you discovered that your son was too heavy for the superman game. Lifting your arms over your head, with your shoulder resisting force, could cause your rotator cuff to tear. It could also be caused by something you’ve done several times before. Maybe you throw that frisbee over the fence every single day because your neighbor’s dog loves it so much, but today it hurt. Too much force could cause it to tear, as well as repeated force (even if the force isn’t that intense).Next
