I am just over a month after bilateral modified radical ND. They maintained jugular, spinal accessory nerve and SMM, but most lymph nodes and other "contents" were removed.

I find that my neck is looser when I am sure to flex and rotate it every hour or so, and be sure to walk or otherwise move around. Sometimes, it will really "cinch up", like a belt tightening, but moving it around for a little bit helps.

My docs tell me to keep both my neck and jaw in motion and flexible, and my recovery will be faster and better, both from the ND and the Radiation. I also have the added problem of having had a two level cervical disk fusion in February, so have stiffness from that as well.

Good luck!
