Welcome and welcome to the
"turkey neck" club

I'm a year out from my neck dissection (hard to believe!) and my lymphedema varies in severity day to day. I have the compression bandages and do some massage but basically I just deal with it. My team and everyone else says it will eventually go away as my body finds alternative drainage routes. There are certain things I equate to it being worse but again, it is what it is and part of the "new normal" for now.
