Hello @susankeel316 Perplexing statement you used to join our group. Seven years. I think many of us have had some issues for years but an open wound and swallowing issues at this point for a tonsil tumor seems extreme to me. It might be time to have a cancer clinic or doctors to have a look.
Swallowing is more complex than most of us imagine. It only takes one or two out of roughly fifty small muscles to malfunction to cause difficulty. Radiation commonly used in cancer treatment often damages these muscles, particularly in your case aimed at the swallowing center, the tonsil pillar.
As for taste loss this long, I think that is not common as well. I had similar cancer and while not a fun couple of years, most functions returned to normal.
We cannot of course diagnose you as most of us a patients as well. We talk of our experience and collectively can point others in a direction they may not have considered to live better in this fight.
Did you have radiation and chemo or just one? Is there a nearby treatment center you could find to investigate this further?
