My ENT also suggested a high power antacid (I have forgoten which one because I never took it) because I had sensations of swallowing problems and feelings of swelling (not large scale) that affected swallowing. The ENT sent me a paper that suggested many symptoms of throat problems were caused by reflux especially when sleeping. In my case the sensation went away after a few more months.

Incidentally, I had problems with pills and certain foods getting "caught" while swallowing and frequently having food or liquids "go down the wrong pipe" (causing a coughing jag). I was worried about this but the ENT was not concerned. (his manner tends to not dwell on a problem if it is not serious. Some might not like his style but to put it in to perspective: One time when I told him I was "Worried" He gently grabbed both my sholders and said "you just let me do the worrying" which I thought was pretty neat )

I am happy to say that this problem has diminished. I believe it was a radiation or lymphedema (swelling) related problem. I recall it may have been more than a year after the end of treatments. Many of the subtle side effects can remain for a long time or perhaps are permanent.

Anita, What I have heard is that the reflux issue is related to cancers lower down than tonsil or mouth. A thought for you: I spent quite a bit of time trying to find the cause of my tonsil cancer with out much success. I believe the strong desire to know is common but my suggestion is to not chase that desire too hard. You'll find a lot of things that might have caused "it" but you'll probably never know for sure. At some point I would like to poll the OCF people about lots of things they may have been exposed to (like lead and arsenic, stress etc.) but even then it would hardly be scientific and as much as it bugs me I probably will never know what caused my cancer for sure.
