how many rads did you have and did you also have chemo. When you try to clear your throat do any food particles come up.I saw an ENT twice for this just recently. Hew scoped me and said everything looks good. It is a swallowing thing so I am doing those excercises wish I had done them from the beginning.Also I feel stuff splashing to the back of my nose. Orange juice burns the heck out of my nose!
