new pain, could the cancer of spread already?!

I carry all my stress in my left shoulder blade. The pain can sometimes be excruciating. The winter doesn't help either as the cold makes me scrunch up my shoulders to my ears just about.

I got the exercise physiologist to have a look at it and she watched me walk and observed I walk with my right shoulder lower than the left. So as @arpie says, pay attention to your posture. Engage your core and all that Pilates jazz. Good luck and let us know how you get on. K xox
