Blood in stools, very sudden since this morning, very bad chills when outside, in last hour when getting home on subway/bus, trembling chills, even though I have 4 layers on and heavy coat, normally not a problem; painful back (ache) but I did a lot of shoveling and snow blowing yesterday, body aches, but hard to relax; somewhat nauseous but feel a bit better after tea and toast. Fatigue. Hot right now but my wife is "blasting the heat."

I work at one of the Boston hospit.als and my primary is good.

Thanks
