@marciefincher Hi, I coughed up blood before. It was liquid blood mixed with pieces. It came on very suddenly and I had no other symptoms except coughing and excess mucus due to allergies. I went to the ER because the quantity of blood was substantial. They kept me there overnight (I went in the evening) and the blood kept coming out throughout the night, soaking up a number of paper towels. It subsided by early next morning and completely stopped by midday. It sure was terrifying to see huge amount of blood coming out every time I coughed. I was subsequently diagnosed with bronchiectasis and MAC. That was 5+ years ago and it has not returned since. That was the only time it's happened to me so far.
