has David been seen by a lymph drainage specialist?...my daughter is a physical therapist and works with a lot of cancer patients...she also does lymph drainage...I had been asking her about this last nite on the phone as I'll be having my surgery soon and this has been a concern of mine...I have BOT SSC and along with removing the tumor they'll be taking lymph nodes, so I'm probably going to be dealing with the same thing that is going on with David...check with your doctors and see if they think referring you to someone that does this would help...good luck with everything...I've only just begun my journey...I can see that it is long, difficult, painful and tiring...be sure to take good care of yourself as well...we need our loved ones to be strong and healthy...Kathleen
