Welcome,
Tjphee to this sanity-saving, info-giving, a light-in -the -dark site full of warm and understanding warriors! Such a good place for you and your boyfriend to begin to find solace and hopefully lessen your 'unknowns'.
Although I beat tongue cancer and an inflamed esophagus after radiation, I can send you my support for your esophageal journey, especially during this wacky COVID mess. It is a true vortex at times I am sure, yet people such as
Brighty have first hand experience as a caregiver to someone who traveled the journey you are on.
Phlegm? It's a tricky one.... hard to clear the throat, hard to swallow solids when the phlegm seems to clog the tubes.....I lost salivary glands, and now I am getting too much phlegm, which causes me to cough and then feel like my throat is shredding.....my cat gets quite concerned with my hacking so I give her way too many treats as a reward for her tolerance.
You are on the brave track and I sure do hope to read more about your state of mind and body as 2021 progresses !!
Drinking supplements such as Ensure or Boost, seems wise..... adding flavouring to water may make it easier for you to tolerate, too.
