he has coughed up blood for the first time and i am really worried.can you please tell me what
this might mean
? also there was no phlegm in the blood
,it was just blood.please help.
P.S: he is a heart patient and has had 2 heart attacks in the past 15 years..recently he had his angiography and angioplasty done and last week he had an appointment with his cardiologist who said he was fine..so i don't think its related to heart but i cant figure out what it could be..can you help..
