I am currently recovering from 3 level ACDF surgery on levels c3-7. I am doing well, and healing. However, today I feel as if I have sprained something in my shoulder. I know that it is caused from wearing the neck collar for so long as my neck, shoulder, arms, wrists are so tight! Does Physical Therapy help this? I can't start PT until at least September 9th. What are your experiences so far. I have been walking every day since surgery, and it does help the tightness a little.
