Hi Seth - in the last couple of months I've been having similar symptoms. I'm exactly 2 years out from my neck dissection and will be 2 years from RT at the end of May.

It began with tingling between my shoulder and neck on the left (my nd side) and in the last couple of weeks I've been getting exactly the cramping you describe. It comes out of nowhere - that is, it doesn't seem motivated by movement - lasts maybe 30 seconds and goes away.

So I can't complain. But now I'm wondering what other wonderful late side effects to look forward to!

Hang in there.
