please advise

I communicate with my doctor
through e mails now, which to me
is interesting, but to her, amusing.
or worse, annoying.
the phlegm is yellow, I write.
wet ribbons of yellow, the dull
sunset yellow of late winter.
they arise from deep within
the cave of my chest. forced out
with a wearying strength.
I feel warm, not a love heat or
even the warmth of infatuation,
but the low burn of a furnace
inside of me,
the coal of ill health being
shoveled into the wide
mouth of my life. my nose
is stuffed up too. please advise.
