Hi, I had a cold that moved to my chest, I have been coughing up opaque mucus, yesterday I took some Tylenol without drinking water and fell back to sleep. When I woke up I cleared my throat and coughed up blood, then the coughing returned to regularl opaque mucus. Tonight I felt the need to cough up again this time it was a clot of blood followed by more mucousy bright red blood.
