HPV squamous cell throat cancer: Soft palate isn't working

I had my surgery on 12/2021 which started in the left tonsil and traveled to the back of the tongue , some of the soft palate, and retro molar trigon. Neck dissection with the removal of 33 lymph nodes, 2 were encapsulated and tested positive. I still need a stomach tube (3/2025) for Glucerna for nourishment. I am 72 years old. My upper(inside) gums get swollen now and then (since 1 year ago) and my soft palate feels like it's touching the back of my tongue. I produce alot of mucous above the palate that prevents me from swallowing food and hard time swallowing water. I constantly have to hack up to clear my palate from the (sometimes yellow) mucous into tissues. I had barium swallow tests done and they claim my soft palate isn't working properly and and swallowing make things (50%) go upward above my palate and could cause me to silently aspirate. I am seeing a speech therapist now to strengthen the throat muscles..Anybody hear or going through these same problems?
