Hello, I am just under 2 years for treatment of hypopharyngeal stage 4. I am all well pretty much but cough up phlegm after coffee or food. Its not a horrible cough, but just a gentle wet cough with phlegm. It doesn't seem to be getting worse nor better after 8 months. I hate googling stuff as it depresses me. Just checking if anyone else had this symptom post treatment long term and whatever comes of it. (my doctor just nods & doesn't seem worried but as the advocate, I would like to know.) Thank you.
