I just finished three weeks of IV antibiotics last week and Friday night..I was doing a Pulmozyme treatment and I coughed up about two table spoons of blood bright red..no sputum..so I freaked out (inside) ofcourse. The problem is that my doctor is 3 and a half hours away. So I just sat very still for the next 4 hours and eventually it slowed down and just became streaks...any advice?
