One side of shoulder blade drops lower than other when hunch forward. doc says muscle issues/soreness. how would sore muscle cause this?

More info: Does this cause you pain? You could just have some asymmetry but could also be a type of scapular winging. I would try shoulder blade strengthening focusing on exercises to squeeze blades together. Also rows and pulldowns. Would not worry much unless having pain.

Possible scoliosis: You might have a rib hump deformity typically seen with scoliosis. Consider an evaluation by your medical doctor or orthopedist.
