I have to keep ,my tongue brushed to keep thrush at bay. It gets a nasty dark color and looks dark grey until I do brush, then everything that comes out while I do is a nasty color like dried blood.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
