Everyday I'll cough up a lump of phlegm which is greenish (I've had this for months and months) the last few days I've noticed there's lots of tiny blood-vessel-like things in there rather than streaks of blood... I have an ongoing problem with my best suspected heart failure by my GP 4 days ago I had an episode which has heart attack like in symptoms and straight away I had an extremely sore throat, struggled to breath and my tonsils blew up red and big and since I've been coughing up these blood vessel like things. I'm 19 female, with ongoing medical problems (syringomyelia and complication due to it)
