Hi,

I started weight training 2 weeks after my disection. it really helps. They usually take the carotid artery when they do the disection, but that shuld have nothing to do with your stiffness. I had PT and it really helped. You need to stretch those muscles and skin. they took a lot of tissue. My neck is still hard in spots but I am massaging, using heat and stretching as much as possible. With some work, it will come back. maybe not as it was, but better than now. At least yor posture will improve. I would begin weight trining ASAP to regain strength. Yoga and pilates help also.
