Dysphagia

Hi everyone! Ever since being diagnosed & starting treatments, (over a year now), I get theses random days where my throat hurts so much, literally as if my throat swells up to which I can not eat, talk, swallow food, liquids & not even my own saliva. It hurts so much & after it’s gone, most times, my throat feels very sore & as if I have something stuck in my throat. I’ve never gotten this before just since the end of last year. I mainly get them very early in the mornings around 6. Never had it before that’s why I’m asking if anyone else experiences this. It’s called dysphagia
