Chest Pain

[Guest]

im currently 19 years old, male, without recent incident, but several years ago, about when i was 14, i suffered 2 attacks of what i believe to be angina. all the symptoms match up, but the only additional one was an incredible amount of mucous produced. I couldnt spit it out fast enough. and when you're doubled over in pain the last thing you think about is where your spit is going. what a mess. anyway, everyonce in a while i feel a little pressure in my chest and im so afraid of another attack. is there something else i could have experienced other than angina? if not, is this the sign of a much larger problem in the very short future? since it was only 2 attacks, and it doesnt follow a pattern, and it was angina, wouldnt it be unstable? if so, why havent i had a problem since then? thanks in advance
