I had it three years ago when it made a comeback. Not only did I start to think it might kill me...when I did get over it,it took more then a year afterwords to feel like I could breathe a full lungful of air. And that cough...just hurt so much. Of course at first I thought it was just another cold...then just another flu..then "What the hell is this?". Later Doctors told me I should have come in for antibiotics but,I since I thought it was just the flu,don't they always tell you "Stay home don't infect people"? I almost good citizened myself into the grave.
Get a flu shot.
