Before you receive some advice from trained professional on the forum, I would recommend that you do some t-spine and shoulder work and find any asymmetry up there. Those shoulder mobs end up attaching to that QL so that will end up given slack.
My vote is that its a strength imbalance starting from the top. Your right side compensates for the left side.
