After surgery - Head and neck, base of tongue, lymph nodes followed by radiation and chemo, you know the drill. I was told during radiation that - it is the gift that keeps on giving and that has certainly been the case for me. Problems swallowing (food and liquids) predominate along with
a tender neck, excess mucus, dental issues, etc. Similar to you....... have seen various specialists with limited results. At 6 years out improvement seems unlikely. Hopefully you will find some relief however it does seem elusive.
