Meredith,
I had a moderate neck disection on November 19th. My range of motion was not effected at all. I had 28 lymph nodes removed. My neck was very tender after surgery. I took Roxicet meds to relieve the discomfort. The discomfort does not last long. My neck still feels numb at times. Your husband should do very well with having a neck disection. I never had Radiation, but from what I here that is way more challenging.
