I was in hospital Dec. of 2017. Had open heart surgery on Nov. 30 afterward of course I was in ICU. 2nd day in ICU I got a bad infection and life support. Cube was put down my throat to breathe. This was down 3 times and then my throat was damaged. Had swallowing therapy. My question! I left the hospital with cough, sneezing, blowing my nose and spitting up clear thick mucus. I have this several times every day and night. It’s over 10 mos.
