@krisohlson Thanks for replying back . So I guess once you get radiation you radiate for life..In other words it keeps working on you. My last throat radiation was in 2022 and I noticed my inside upper gums near my teeth or the roof of my mouth gets blistered now and then. This only started less than a year ago. I have had this mucous problem since after radiation which is coming from "above" the roof of my mouth 24/7. I am constantly snorting to get it out. I also use that nasal saline spray that helps getting it to slowly ooze out..Mucous won't come out by blowing my nose because it's thick. It feels like a marble above my soft palate which is obstructing my swallowing even after I get rid of it. I can swallow little gulps of water if I turn my neck to the left. I am seeing a speech therapist for the swallow exercises.
