Hi Dan,
You describe EVERYTHING I have experienced the past few months. I also was kind of lazy about getting back into eating, it was so much easier and quicker to just use the tube. But, that will all of a sudden just go away and your appetite will come back full speed. I also have a very tender neck, more tender now then it was right after radiation. My right shoulder has been giving me some problems, wondering if I pulled a muscle but I swear it's from the way I hold my arm and hand when I am on the computer. Lots of new feelings in my neck and jaw lately.
I also had the thick, white saliva. It's better now but still have the white tongue in the morning.
Depression seems to be our new friend, and that's just how I treat my small case of it. I baby it, give it some attention, then move on with myself.
It sounds like you're doing wonderful Daniel, keep your chin up.
Minnie
