Yeah... I would want to make sure the dr. is aware and looks at the area. I know that during rads your throat and tonsils are pretty sore, raw, and bloody etc... but the devil is in the details. It could be that maybe over night small amounts of blood accumulate so in the morning when you are clearing the guck it all comes out at once. During the day thanks to gravity you probably swallow most of it without realizing - it's only when sleeping that it may pool However, the dr should me made aware - they didn't remove his tonsils? That is odd - normally because it's a tonsil they will remove it then do rads and chemo. That way the tumor is essentially gone... Hugs.
