Shortness of breathe and sometimes chest pain.
21M
From past 15 days I have been feeling shortness of breathe like I have to take deep breathes from mouth in between.It started where I have to take deep breathes from mouth even at rest but now from past few days the frequency of taking deep breathes at rest has been decreased but its still there.Shortness of breathe increases little bit when I do some activity like climbing stairs.Also I have been having left sides chest pain near armpit and under armpit but its intermittent not every time.I have been dealing from health anxiety from past 6 months.I have consulted with cardiologist and he has done ecg on me which showed sinus tachycardia where my pulse was 103 bpm but rest everything was normal.But I told Doc to take me for 2D echo for clarification but I am also afraid of 2D echo results as I don’t want any heart disease at such young age.What do you guys think that whether its heart failure or something related to heart?
