Donnajean, it has been one year since my modified radical neck dissection, and I have residual numbness that I expect to have forever more. There has been a great improvement in feeling in the past year, and I even think some continuation of improvement now. For example, now when my neck itches and I scratch it, I can feel it. Not as acutely as on the undamaged side, but still a lot better than before. I think patience is the virtue necessary here. As far as the remaining numbness, I look on that as a small price to pay for what I gained from the surgery. Tell your husband to hang in there. I am sorry about the continued swelling and have no suggestions. I do know that my neck still feels tight in the evenings, but that is not visible.

Edited to add that I wouldn't advise use of an electric massager without an okay from the doc.
