Sometimes my feet, but mostly, I have numbness/pain that jumps from one side of my lungs, to the other, and sometimes centers in my chest, and it feels numb, like I don't have a heartbeat. I'm coughing
heavily, and sometimes they're rough. I cough up
a lot of phlegm
that's usually green, yellowish, sometimes white with specks, and only once after having a tooth pulled have I ever coughed up blood, so I highly doubt, at least for now, that anything serious is going on.
