Frankie, with cranial nerve XI irritated, it may take a while to get the muscles going on the top of the shoulder and scapula on the side it was moved around. I hope the PT explained even if it hurts, you need to keep it stretched and iced as often as possible along with some exercise to keep the blood moving. That's the biggest challenge in preventing permanent atrophy. It may hurt for a while but you should get decent range of motion and reduced pain with time.
