Bobbie,
Hello and welcome to this wonderful club that none of wanted to join, but we're so glad it's here.
As far as the swallowing goes that too is different for everybody. I am 18 months out from radiation and still got some vitamins caught in my throat last week. Some days are better than others. Really you aren't that far out from radiation. We all heal differently and it's been said that it takes a month for every week of radiation. So maybe it's just too soon for you. Don't push it, do what you can and take the rest easy.
There are some on this board (digtexas) that had help due to swallowing problems, but that was further out from radiation when they knew it was a problem not a normal side effect.
There is a Support For People With Head & Neck Cancer Group on the internet. I believe they have a support group inb Dallas. If I find more information I'll let you know.
Take care,
Dinah
