I've had something similar.
For the past 6 days I've had either a v.heavy cold or the flu. Incredible amounts of green and bloody mucuous from my nose. Got through 3 rolls of toilet paper. My nostrils have been caked in dried snot/blood. On th e 5th night, I woke up choking on a crusty and bloodied flake of snot. Similar thing happened twice the next day and couldn't work out if it was from nose or throat but the Adenoids make sense. Mucous from chest was like a knot of wet cheese. Has now thinned out and moved to to the chest and become a cough.
