Over the past 3 days when I work the lacrosse ball around my scapula (Episode 18) I feel like I’m hitting a nerve at the top (where he places the lacrosse ball initially in the video).  It sends a shooting pain up my shoulder to to the back of my neck.  My thoughts are:  stop using the lacrosse ball and focus on stretching for a bit.  Correct or incorrect?  Any additional thoughts?
