Hi Sylvia, sorry you have cause to join us all here.
I agree with Christine that you should definitely get this checked out with your Husbands medical team. I think the fact that he can swallow is somewhat reassuring.
The bilateral neck dissection does in itself cause a very hard and stiff neck. My husband was unable to turn his neck for 6 months postop and needed Physiotherapy for 3 months to help loosen up both the neck and shoulder muscles. This has taken a lot of work and Kris continues to work on these muscles by going to the gym a couple of times a week. Radiation makes it all worse and causes the tissues in the neck to become really hard, - like concrete.
After 3 months of intensive PT Kris was back driving, mowing lawns , using the chainsaw, hanging out the laundry etc.
Hope this helps,
Tammy
